ethylene-vinyl acetate copolymer
polymerEthylene-vinyl acetate (EVA) copolymer is a flexible thermoplastic formed by copolymerizing ethylene with vinyl acetate monomers, combining the toughness of polyethylene with the softness and tackiness imparted by vinyl acetate content. EVA is widely used in footwear (midsoles, insoles), cushioning applications, flexible tubing, and protective packaging due to its low-temperature flexibility, impact absorption, and processability. Engineers favor EVA over rigid plastics when conformable cushioning with moderate temperature performance is needed, and over natural rubber when consistent processing, lighter weight, or lower cost is prioritized.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
