Downstream process integration

• Dry-blending with flame retardant, pigment, and processing aid additives, then melt-compounded using twin-screw extruders before pelletizing. Formulated pellets are later extruded onto copper or aluminum conductors in cable fabrication lines.

Final product types

• Primary and secondary insulation layers for building wires
• Flexible sheaths for data cables and telecom cords
• Automotive wiring harness insulation
• Low-smoke, halogen-free flame retardant (LSZH) cables

3. Solar Photovoltaic Encapsulant Sheets

Photovoltaic module manufacturers require EVA resins to create encapsulant films that protect solar cells from environmental moisture and mechanical stress. This material’s clarity and crosslinking response ensure stable light transmission while maintaining thermal and UV resistance. Leading solar panel producers control formulation and film thickness to optimize module efficiency and lifetime in field exposure.

Industry compliance standards

• IEC 61215 (Crystalline silicon photovoltaic module testing)
• UL 1703 (Flat-plate PV modules and panels)
• ISO 9001 and ISO 14001 (Environmental management in module manufacturing)
• RoHS for restricted substances

Typical usage ratio

• Base formulation consists of 100% EVA copolymer for the encapsulant, with <1% additives (crosslinkers, UV stabilizers, antioxidants). Film thickness commonly 0.45–0.55 mm to balance physical protection and light transmittance.

Downstream process integration

• EVA pellets melt-compounded and extruded into sheet form via calendaring or flat die extrusion, followed by lamination onto PV cells in a vacuum or hot-air laminator before final module assembly.

Final product types

• Encapsulant films for silicon PV modules
• Flexible encapsulant layers in building-integrated photovoltaics
• Backsheets in lightweight solar modules
• Specialty encapsulants for thin-film solar cell technology

4. Footwear Midsoles and Outsoles

Sports shoe and work footwear manufacturers select EVA for midsoles and outsoles requiring controlled resilience, low density, and frequent flex without cracking. Blending ratios are key to achieving hardness profiles for different market segments, such as athletic performance shoes, orthotic footwear, and safety work boots. Manufacturers add colorants and blowing agents during the compounding stage to achieve light, shock-absorbing foams.

Industry compliance standards

• REACH registration for direct skin contact substances

Downstream process integration

• Added alongside blowing agents, pigments, and crosslinkers during batch mixing, then directly processed through injection molding or batch pre-foaming and compression molding for footwear assembly lines.

Final product types

• Shock-absorbing midsoles for athletic and running shoes
• Anti-fatigue outsoles for safety and occupational footwear
• Lightweight sandals and slippers
• Custom orthotic inserts

5. Film Modification and Coextrusion Masterbatches

Producers of industrial and agricultural films use EVA as a modifier to improve tear resistance and low-temperature sealability in multilayer film construction. Well-defined rheology and crystallinity ensure uniform blending with LDPE or LLDPE for greenhouse films, heavy-duty sacks, and stretch hoods that must perform reliably in automated packaging and field exposure applications.

Industry compliance standards

• EN 13206 (Plastic films for greenhouse covers)
