Typical usage ratio

• 35% – 55% by weight in injection-molding compounds for midsoles and outsoles; ratio selected to control hardness, rebound, and density

Downstream process integration

• Compounded with blowing agents and crosslinkers in banbury mixers, granulated and fed to high-pressure injection molding, followed by in-mold foaming and cooling

Final product types

• Sports shoe midsoles
• Work boot outsoles
• Children’s sandal bases

5. Film Extrusion for Greenhouse and Agricultural Covers

Producers of agricultural films add this EVA grade into PE-based film blends to improve optical clarity, cold-resistance, and flexibility, ensuring compliance with demanding field deployment standards. Its controlled vinyl acetate content provides anti-fogging and light dispersion properties essential for specialty greenhouse films and protective crop covers.
