Typical usage ratio

• 65–75% by weight in encapsulant sheet core; compounded with crosslinkers and antioxidants. Ratio depends on required film thickness and cross-link density.

Downstream process integration

• Hot-melt extrusion, pellet-to-sheet calendaring, followed by in-line cross-linking during solar panel lamination step (glass/EVA/cell/EVA/backsheet assembly).

Final product types

• P-type mono/polycrystalline solar panels
• Bifacial photovoltaic modules
• Flexible photovoltaic sheets (for BIPV, vehicle rooftop applications)

2. Hot Melt Adhesives for Packaging and Labeling

This EVA resin’s controlled viscosity and elasticity make it suitable for pressure-sensitive and hot melt adhesive bases, especially in industrial packaging and labelstock lines where clean machinability and consistent bond strength on diverse substrates are critical. Our raw material supports short open time and quick set formulations, optimizing high-speed assembly lines.

Typical usage ratio

• 18–35% by total adhesive batch; varies with required open time, bonding target, and compatibility with tackifiers/waxes.

Downstream process integration

• Direct addition to adhesive compounding kettles, scaleable for continuous or batch melting, followed by blend with resin modifiers and line-extrusion to form glue pellets or blocks.

Final product types

• Carton sealing glues
• Pressure-sensitive adhesives for labels/tapes
• Bookbinding adhesives
• General packaging hot melts for rigid and flexible packaging lines

3. Footwear Midsoles and Outsoles Manufacturing

Our Greenflex ML 60 EVA is widely adopted by footwear OEMs and ODMs for its high resilience and microcellular expansion balance in midsole and outsole compounds. Processors value its foamability and dimensional stability during injection and compression molding, supporting stable large-scale shoe production with a strong focus on lightweight ergonomics and end-use durability.

Industry compliance standards

• ISO 20871:2018 (Footwear—outsole abrasion resistance)
• ISO 9407:2019 (Footwear sizing/labeling)

Typical usage ratio

• 55–85% in compound; adjusted based on density target and blend with blowing agents, fillers, color masterbatches.

Downstream process integration

• Compounded in Banbury or twin-screw mixers, then fed to automatic injection or compression foam molding lines. Allows for single or dual density part construction.

Final product types

• Sports shoe midsoles
• Casual footwear outsoles
• Slippers and sandals
• Orthopedic insoles and foam pads

4. Wire and Cable Insulation Sheathing

Cable manufacturers rely on this raw material for primary and secondary layer insulation in electrical wire due to its electrical resistance, flexibility, and environmental crack resistance. Its clean melt characteristics help minimize gel formation during cable extrusion, supporting stable yields in power, data, and automotive wire production lines.

Industry compliance standards

• UL 1581 (Electrical wires and cables)
• IEC 60228 (Conductors of insulated cables)
• RoHS (Restriction of Hazardous Substances in electrical/electronic products)
• CSA C22.2 (General wire and cable standard, Canada)

Typical usage ratio

• 60–100% of insulation compound formulation; the ratio depends on whether applied as pure sheath or in blend with plasticizers and fire retardants.

Downstream process integration

• Dry-blended or melt-compounded with flame retardants and processing aids, pelletized, then applied via continuous screw extrusion onto copper/aluminum conductors before cooling, spooling.

Final product types

• Low-voltage building wire (insulation)
• Automotive wire harness insulation
• Flexible appliance cables
• Coaxial and signal cable sheathing

5. Film and Sheet for Agricultural Greenhouse Covers

Manufacturers of multilayer greenhouse films specify this EVA grade to balance flexibility and longevity, especially in climates with severe thermal swings. Its high VA content supports UV-transparency and enhanced puncture resistance, allowing coextrusion with LDPE or UV stabilizer masterbatches for high-output agricultural film lines.

Industry compliance standards

• EN 13206:2021 (Plastics—film for agricultural mulch and covering applications)

• Regulation (EU) 2019/1009 (Fertilizing products—Film biocompatibility section)

Typical usage ratio

• 8–25% by total film layer; ratio determined by required film elasticity, light transmission, and application of other co-monomers in multilayer structures.

Downstream process integration

• Dry blending of pelletized EVA with LDPE/LLDPE and functional additives in gravimetric feeders, then blown or cast film extrusion in multi-chill ring dies; slit or rolled according to farm deployment width.

Final product types

• Single/multilayer greenhouse covers
• Thermal insulating films for tunnel farming
• Agricultural mulch sheets
