What is EVA Plastic Granules?

EVA plastic granules, or ethylene-vinyl acetate copolymer granules, are thermoplastic polymer granular materials synthesized by the copolymerization of two monomers: ethylene and vinyl acetate.
EVA plastic granules can be classified into many kinds of items according to different standards. Common examples include FDA Compliant EVA , REACH Compliant EVA, RoHS Compliant EVA, LFGB Compliant EVA, ISO 9001 EVA, ISO 10993 (medical-grade) EVA, UL94 Flame Retardant Certification (V-0/V-2) EVA, Non-Toxic Certification EVA, Low VOC EVA, BPA-Free EVA, GRS Certification (recycled EVA), Food-Contact Approval EVA, Skin-Contact Safety Certification EVA.

Advantages and Disadvantages

EVA (ethylene-vinyl acetate) plastic granules are versatile thermoplastic copolymers, with pros and cons tied to vinyl acetate (VA) content.

Advantages
Performance is adjustable via VA content-low VA (5%–10%) offers rigidity and heat resistance like PE; high VA (20%–40%) provides flexibility, toughness and adhesion similar to rubber. It supports diverse processing (injection molding, extrusion, foaming, blow molding) for mass production, and has excellent low-temperature resistance, remaining flexible at -50°C without brittleness. Food/ medical-grade EVA is non-toxic, BPA-free and safe for food packaging, toys and medical devices. It resists weak acids, alkalis and most solvents, with good aging resistance, and high-VA EVA bonds well with metals, fabrics and plastics for adhesives.

Disadvantages
Poor high-temperature resistance (heat distortion at 60–80°C, softening above 90°C) limits high-heat uses. Its mechanical strength is lower than engineering plastics like ABS/ PC, making it unsuitable for load-bearing parts. Long-term contact with oils/ solvents causes swelling and performance loss. It costs more than PE, and mixed/ EVA foam products are hard to recycle.
