In compression-molded midsole manufacturing, HANWHA EVA 1519 is combined with a chemical blowing agent, dicumyl peroxide, and activators in an internal mixer whose rotor speed is held between 30 min⁻¹ and 40 min⁻¹; the drop temperature is limited to 105–115°C because dicumyl peroxide under these conditions begins generating cumyloxy radicals near 140°C, leaving a scorch safety window of approximately ±5°C before irreversible gel formation appears. The formulation shown in Table 1 is used for closed-cell midsoles with target density 0.18–0.25 g/cm³ and Shore Asker C hardness 45–55 under ASTM D2240; amine-based additives are excluded because they accelerate peroxide decomposition and narrow the scorch margin. Compliance is anchored to REACH EC 1907/2006 and Annex XVII restrictions for polynuclear aromatic hydrocarbons and phthalates, with finished midsoles tested for compression set under ASTM D395-18, flex fatigue under ISO 17707, and hardness under ASTM D2240; occupational footwear is additionally assessed under EN ISO 20344:2021 for energy absorption and microporous sole bonding. The production sequence uses a two-roll mill at 95–105°C for homogenization, followed by sheet pre-forming and multi-cavity compression vulcanization at 160–170°C for 6–9 min; during this step azodicarbonamide decomposes at the effective process temperature in the presence of zinc oxide, expanding the melt while the peroxide crosslinks the polyethylene segments. Terminal product types include compression-molded midsoles for running shoes, cross-training footwear, casual sandals, and safety boots.

Continuous crosslinked foam-sheet production selects EVA 1519 when sheet thickness falls between 2 mm and 30 mm and the calendered pre-foam must retain dimensional stability under low tension through a hot-air vulcanization tunnel; the resulting expanded sheet typically ranges from 0.10 g/cm³ to 0.20 g/cm³ in apparent density and from 0.2 mm to 1.2 mm in mean cell diameter depending on blowing agent particle size distribution. Compliance testing under ASTM D3575-20 addresses tensile properties, compression set, and density of flexible cellular olefin materials, while ISO 7214 governs cellular plastics and EN 71-3:2019 applies where sheet foam is converted into children’s exercise or play mats; REACH Annex XVII controls restricted phthalates and polynuclear aromatic hydrocarbons in the final article. The foaming formulation uses 100 phr EVA 1519, 2.0–3.5 phr azodicarbonamide, 0.5–0.8 phr dicumyl peroxide, 0.8–2.0 phr zinc oxide, and 5–15 phr calcium carbonate; lower peroxide dosage relative to molded midsole work prevents surface over-cure during long tunnel residence. Processing requires a two-roll mill at 95–105°C to produce a homogeneous hide, a calender to form the sheet, and a continuous vulcanization oven operating at 180–220°C with dwell times of 8–15 min depending on sheet gauge. Terminal product types include yoga mats, gym flooring, protective packaging dunnage, and helmet impact liners.
When halogen-free cable jackets are formulated with 150–180 phr precipitated aluminium trihydroxide and 5–10 phr zinc borate, EVA 1519 provides the polar matrix required to accept high filler loading without undergoing melt fracture at the crosshead die. Reported oxygen index values for similar EVA/ATH systems reach 30–34% under ISO 4589-2, though published data for this exact EVA 1519 grade in CPR-classified jackets remains limited; pilot compounding is required to confirm smoke density and acid gas correlation. Compliance is evaluated under IEC 60754-1/2 for halogen acid gas evolution, IEC 61034-2 for smoke density, EN 50575 for construction product cable classification, and ISO 6722 where automotive harness insulation is produced. The compounding formulation consists of 100 phr EVA 1519, 20 phr LDPE, 150–180 phr ATH, 5–10 phr zinc borate, 2–5 phr maleic anhydride graft coupling agent, and 0.5–1.0 phr hindered phenolic antioxidant; filler side-feeding is executed on a co-rotating twin-screw extruder with L/D 44:1, barrel set points 120–150°C, and screw torque maintained below 85% of drive rating. ATH must be pre-dried at 80°C for 2–4 h when ambient relative humidity exceeds 60% or when filler surface moisture exceeds 0.2 wt%. Finished compound is then extruded onto copper or aluminium conductors through a single-screw crosshead extruder at 180–200°C. Terminal product types include building riser cable jackets, automotive harness wall insulation, and solar array cable jackets.
EVA 1519 at 15 wt% vinyl acetate and 1.9 g/10 min melt flow rate acts as a high-shear carrier in additive masterbatch formulations where melt temperatures must remain below 180°C to protect heat-sensitive organic pigments. The polar acetate group reduces interfacial tension with titanium dioxide and iron oxide pigments, permitting dispersive mixing in a co-rotating twin-screw extruder with L/D 44:1 and screw speeds 400–600 min⁻¹. Compliance requirements are set by ISO 1133-1:2022 for melt flow rate, ISO 527-2 for tensile properties, and 21 CFR 177.1350 where the final polyolefin package contacts food; REACH registration for EVA copolymers is maintained under EC 1907/2006. A typical carrier formulation uses 20–40 wt% EVA 1519, 40–60 wt% pigment or additive, and 5–10 wt% polyethylene wax, with barrel set points from 120°C in the feed zone to 170°C at the die, followed by water-ring pelletizing and classification to reduce fines below 0.5 wt%. Terminal product types include color masterbatches for polyethylene films, flame-retardant concentrates for EVA/LDPE foam, and impact-modifier compounds for polypropylene sheet.
Conventionally, injection molded flexible closures and gaskets produced from EVA 1519 are modified with 10–20 wt% calcium carbonate to reduce sink marks and improve dimensional stability; the melt index of 1.9 g/10 min under ASTM D1238 limits thin-wall filling unless melt temperature is held at 180–200°C and gate dimensions are increased beyond those used for high-flow polypropylene. Compliance is governed by 21 CFR 177.1350 for repeated-use food-contact articles, EU RoHS Directive 2011/65/EU for lead, mercury, cadmium, hexavalent chromium, PBB and PBDE, and REACH Annex XVII for restricted plasticizers. Injection molding machines with clamp forces from 500–1,200 kN are used at 30–60°C mold temperature, with holding pressure maintained until gate freeze and screw recovery set to avoid plastication shear heating above 210°C. Terminal products include flexible bottle caps, cosmetic jar gaskets, appliance feet, and anti-skid pads.
Extruded profile gaskets produced from EVA 1519 blends with 20–30 wt% LDPE and 5–10 wt% EPDM exhibit improved notch tear resistance under ASTM D624 and lower compression set after 22 h at 70°C under ISO 815-1:2019; the EPDM phase contributes elastic recovery without requiring a separate vulcanization step. Compliance standards include ASTM D638-14 for tensile properties, ASTM D2240 for Shore A hardness, UL 94 HB for flame class in building edge trims, and REACH Annex XVII for restricted additives; dimensional tolerance is evaluated under ISO 3302-1 for extruded rubber profiles. The production line uses a single-screw extruder with L/D 30:1, a crosshead die, and a vacuum-calibration tank maintained at 15–25°C; barrel temperatures ascend from 150°C in the feed zone to 190°C at the die to avoid melt fracture while preserving profile geometry. Terminal product types include door seals, window glazing gaskets, refrigeration door profiles, and edge-protection trims.

HANWHA EVA 1519 is an ethylene-vinyl acetate copolymer grade with a nominal vinyl acetate content of 15 wt% when determined by ISO 8985:1998 and a melt mass-flow rate of 1.9 g/10 min when measured at 190°C under a 2.16 kg load according to ISO 1133-1:2022. The manufacturer-reported density is 0.938 g/cm³ when tested to ISO 1183-1:2019. These values position the grade between 13 wt% vinyl acetate types such as EVA 1315, which offer higher crystallinity and lower polar adhesion, and 15 wt% vinyl acetate grades with melt flow rates above 2.5 g/10 min, which offer easier injection molding but reduced melt strength. Tensile strength at break is approximately 18 MPa and elongation at break approximately 700% when tested to ISO 527-2:2012, with Shore D hardness of 44 measured by ISO 868:2003. These are representative technical data sheet values, not release limits.
Thermal degradation in EVA 1519 proceeds by ester pyrolysis of the vinyl acetate side groups, releasing acetic acid and forming conjugated unsaturation in the polyethylene backbone. Sustained melt temperatures above 200°C initiate measurable acetic acid evolution, and degradation accelerates sharply above 230°C. Production-scale single-screw extruders with screw diameters of 65 mm and L/D ratios of 28:1 therefore maintain die-lip melt temperatures between 175°C and 205°C to reduce gel formation and chrome-plate plate-out. The grade is incompatible with primary amines and strong alkalis, which catalyze ester hydrolysis and can produce premature crosslinking, discoloration, and low-molecular-weight volatiles. Screw designs with compression ratios from 2.5:1 to 3.0:1 and barrel zones using reverse temperature profiles limit melt residence time. After processing, a purge with low-density polyethylene is required before shutdown because EVA 1519 held at melt temperature for more than 30 min can deposit carbonaceous residue on screw flights and barrel walls.
Closed-cell crosslinked foam sheet production using EVA 1519 generally employs a counter-rotating conical twin-screw extruder with screw diameter of 92 mm and L/D ratio of 36:1, operated at a melt temperature of 115°C to 125°C to delay peroxide decomposition during mixing. Azodicarbonamide blowing agent loadings from 6 phr to 12 phr and dicumyl peroxide loadings from 0.8 phr to 1.4 phr generate foam densities of 0.08 g/cm³ to 0.20 g/cm³ in sheet form. The 1.9 g/10 min melt flow rate of EVA 1519 improves bubble retention during expansion relative to grades with melt flow rates above 3.0 g/10 min, because the higher melt strength reduces cell coalescence under biaxial stretch at the calender. Final foam mechanical properties are evaluated by ISO 1798:2008 for tensile strength and elongation, and compression set after 50% deflection is measured by ISO 1856:2018. Published grade-specific data for all formulation variants is limited; converter trials are required to fix exact density and hardness.
Extrusion lamination of aluminium foil, paper, and oriented polyester film with EVA 1519 uses the vinyl acetate functionality to promote wet-out and adhesion on polar metallic surfaces, but the low melt flow rate requires a shorter air gap and higher backpressure than low-density polyethylene. On a 90 mm single-screw laminator with L/D ratio of 30:1, melt temperatures at the die exit from 215°C to 225°C and an air gap of 100 mm to 150 mm provide consistent coating weight without excessive neck-in. Peel adhesion of a 20 µm EVA layer on aluminium foil is measured by ASTM F904-16; reported values in industrial lamination typically exceed 2.0 N/15 mm when substrate preheating above 30°C is applied. Compared with EVA grades containing 18 wt% vinyl acetate, EVA 1519 exhibits higher tensile modulus and better heat resistance but lower adhesion to high-polarity substrates and reduced low-temperature flexibility. Published data for this specific grade in thin-film extrusion lamination remains limited, so pilot-line verification under ISO 11339:2022 is necessary before full commercial qualification.
On injection molding lines with clamp force from 1,200 kN to 2,000 kN, EVA 1519 is processed with barrel temperatures from 150°C to 190°C, mold temperatures from 20°C to 40°C, and injection pressures from 60 MPa to 120 MPa. Mold shrinkage after 24 h at 23°C is typically 1.5% to 2.0% in the flow direction when measured according to ISO 294-4:2018. Ejection from polished steel cavities requires mold release systems free of amine-based active ingredients; unmodified EVA may adhere to metal surfaces and generate sticking during high-speed cycles. Cyclic compression fatigue is evaluated on a servohydraulic tester at 5 Hz to 10 Hz; published data for this exact grade under footwear-type flexing is limited. The material is not recommended for contact with aromatic or chlorinated solvents, which induce swelling and extraction of low-molecular-weight fractions.

Representative values in the comparison table are drawn from publicly available technical literature for ethylene-vinyl acetate copolymers with equivalent nominal composition and are not release limits for any single production lot. The principal differentiation of EVA 1519 is the combination of 15 wt% vinyl acetate and 1.9 g/10 min melt flow rate, which provides a processing window between low-flow film grades and high-flow injection grades.
Under EU Regulation No 10/2011, EVA 1519 may be used in food-contact layers if the finished article meets overall migration limits evaluated by EN 1186-1:2002; the converter must account for the vinyl acetate monomer specific migration limit and any adhesive or slip additives. FDA status for ethylene-vinyl acetate copolymers is defined in 21 CFR 177.1350, but compliance is not intrinsic to the polymer and requires verification of the full formulation. RoHS Directive 2011/65/EU heavy metal thresholds are assessed by IEC 62321-5:2013 for cadmium and IEC 62321-4:2013 for lead; raw-material certificates should be retained. REACH Regulation (EC) No 1907/2006 requires confirmation that no substances of very high concern exceed 0.1 wt% in the supplied pellet, based on the Candidate List current at the time of import.
Moisture uptake above 0.05 wt% by Karl Fischer titration can cause surface defects and microvoids in extruded profiles and sheet. Pre-drying in a desiccant dryer at 60°C to 70°C for 4 h to 6 h is required when storage relative humidity exceeds 60% or when pellets have been exposed to ambient air for more than 72 h. Drying temperature above 80°C is not recommended because pellet agglomeration can occur before the moisture is removed.
| Regulatory requirement | Assessment method | Relevance for EVA 1519 |
|---|---|---|
| EU Regulation No 10/2011 | EN 1186-1:2002 overall migration | Compliance must be verified on the finished article under applicable food simulant and time/temperature conditions. |
| FDA 21 CFR 177.1350 | Ethylene-vinyl acetate copolymer resin status | Grade-dependent formulation and end-use compliance required; not automatically granted by resin type alone. |
| RoHS Directive 2011/65/EU | IEC 62321-4:2013, IEC 62321-5:2013 | Supplier certificates must confirm heavy metal thresholds for each production lot. |
| REACH (EC) No 1907/2006 | Candidate List screening | SVHC content above 0.1 wt% must be excluded or declared by the importer. |
Profile extrusion of EVA 1519 on a 60 mm single-screw extruder with breaker plate and screen pack, operating at melt temperatures from 160°C to 190°C, produces gaskets, tubing, and edge-protection profiles. The low melt flow rate of 1.9 g/10 min supports dimensional stability after die swell, but line speed must be reduced relative to higher-MI grades to compensate for higher head pressure and shear heating. Draw-down characteristics are evaluated by measuring profile cross-sectional area against haul-off speed; a draw ratio of 1.1:1 to 1.5:1 is typical for this grade. Because EVA 1519 has a Vicat softening temperature of approximately 74°C when tested to ISO 306:2022, continuous service at temperatures above 60°C under load can cause dimensional recovery issues.
