Applications of Hyundai VA600 EVA in Industrial Manufacturing

Hyundai VA600 EVA serves as a specialty copolymer widely used in demanding downstream sectors, where exacting processing and international compliance standards are critical. The following application scenarios illustrate how downstream manufacturers integrate this material in advanced production environments.

1. Solar Photovoltaic Encapsulation

Downstream solar module manufacturers utilize this material primarily as an encapsulant layer in photovoltaic panel lamination. The material’s reliable melt flow and vinyl acetate content allow precise control in extrusion and sheet casting, supporting strict cell protection and transparency benchmarks. Proper formulation and lamination maintain high transmittance, UV resistance, and strong adhesion to glass and solar cells, which are mandatory for both crystalline silicon and thin-film PV modules.

Industry compliance standards

• IEC 61215 (Crystalline silicon terrestrial PV modules design qualification and type approval)
• UL 1703 (Standard for Flat-Plate Photovoltaic Modules and Panels)
• RoHS Directive (2011/65/EU)
• ISO 9001 and IECQ QC 080000 management systems

Typical usage ratio

• Encapsulant layer content: 30–32% by weight of module total laminate; can range from 380–550 g/m² depending on cell size and lamination line

Downstream process integration

• Feeds into sheet extrusion or cast film lines; forms the core encapsulant sandwich between tempered front glass and backsheet before vacuum lamination

Final product types

• Monocrystalline and polycrystalline PV modules
• High-efficiency bifacial solar panels
• Building-integrated photovoltaic (BIPV) glass
• Flexible solar film panels

2. Footwear Midsoles and Outsoles Manufacturing

Footwear compounders and OEMs formulate Hyundai VA600 EVA with blowing agents and stabilizers to produce midsoles and lightweight outsoles for athletic and casual shoes. The defined melt index supports controlled foaming and excellent cell structure, enhancing resilience, comfort, and long-term compression set. Strict adherence to restricted substance lists and wear-resistance tests ensures the resulting soles meet global retail and sports brand audit criteria.

Industry compliance standards

• ISO 20871 (Footwear—Test methods for outsoles—Abrasion resistance)
• ISO/TR 16178 (Footwear—Critical substances regulation)
• REACH SVHC regulations
• Brand-specific RSL (e.g., Nike, adidas A-01)

Typical usage ratio

• Base polymer share: 60–75% in foam compounds, adjusted based on hardness and expansion required

Downstream process integration

• Melt-mixed in Banbury or twin-screw extruders, then injection molded or compression foamed; integration point is before blowing agent decomposition and mold shaping

Final product types

• Compression-molded athletic shoe midsoles
• Injection-foamed lightweight outsoles
• Children’s shoes and slippers
• Anti-fatigue work and industrial footwear

3. Hot Melt Adhesives Production

Pressure-sensitive and packaging adhesive manufacturers select this EVA for blending with tackifiers, waxes, and stabilizers to manufacture hot melt adhesives (HMA) used in bookbinding, carton sealing, and hygiene disposables. Its consistent vinyl acetate level provides control over open time, set speed, and adhesion on difficult substrates. Downstream processes require tight monitoring of melt viscosity and compatibility with various base polymers or additives to meet final joint strength and aging demands.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives in food packaging)
• EU No 10/2011 (Plastic materials and articles intended to come into contact with food)
• C28-400 thermogravimetric testing
• ASTM D1876 (Peel resistance of adhesives)

Typical usage ratio

• Base polymer fraction: 25–45% of hot melt adhesive blend, modified according to application viscosity and substrate characteristics

Downstream process integration

• This raw material feeds into high-shear mixers or reactive extrusion at temperatures 120–180°C, forming the adhesive’s backbone prior to pelletizing or direct drum packaging

Final product types

• Bookbinding HMAs
• Carton and case sealing adhesives
• Disposable hygiene product glue lines (diapers, feminine care)
• Pressure-sensitive label adhesives

4. Wire & Cable Insulation Compounds

Compounders in wire and cable manufacturing incorporate this EVA grade as a key polymer matrix for insulation and sheathing on low-voltage and telecommunications cables. Its high vinyl acetate content provides enhanced flexibility, flame retardancy, and dielectric performance. Precise dosing and mixing with crosslinking agents and FR additives guarantee cable insulation performance specified in telecom, power, and automotive standards. The production chain carefully implements two-step compounding before extrusion or irradiation crosslinking.

Industry compliance standards

• IEC 60502-1 (Power cables with extruded insulation)
• UL 758 (Appliance Wiring Material)
• RoHS and REACH for hazardous substances
• CSA C22.2 No. 49 (Flexible cords and cables)

Typical usage ratio

• Base polymer: 35–65% of insulation compound, dependent on cable voltage rating and flexibility targets

Downstream process integration

• Melt-blended with FR agents, antioxidants, and crosslinking chemicals, then pelletized; re-melted and extruded as the insulation or sheath layer in continuous cable lines

Final product types

• Telecommunications wire insulation
• Low-voltage power cables
• Flexible appliance cords
• Automotive wiring harnesses

5. Medical Device and Pharmaceutical Packaging Films

Medical packaging film producers rely on carefully controlled, traceable Hyundai VA600 EVA to formulate barrier and sealant layers for pharmaceutical blister packs, IV fluid bags, and high-clarity pouches. Selection centers on absence of extractables, consistent melt flow, and reproducible sealing at low temperatures. Supplier traceability, GMP documentation, and batch testing underpin delivery to regulated medical device and pharma film converters.

Industry compliance standards

• USP <88> and <87> (Biological Reactivity Tests)
• ISO 11607-1 (Packaging for terminally sterilized medical devices)
• FDA 21 CFR 177.1350 (Ethylene-vinyl acetate copolymers for food-contact and medical applications)
• EU 2017/745 (Medical Device Regulation)

Typical usage ratio

• Primary film layer: 25–40% of total film composition, modified for barrier requirements and mechanical strength

Downstream process integration

• Fed into blown film or coextrusion processes as the main barrier or sealing layer, followed by printing and slitting according to packaging line integration
