Material: EVA Features: cushion , shock-proof , thermal-insulation , chemical corrosion and etc., without poision and water absorption, it can be cut and formed , owning to vast density difference, it can be used more widely. Water resistance,sealing size structure, without water absorption, moisture-proof and high water proof performance. Corrosion resistance sea water, oil grease, acid, alkali and other chemical substance resistance, bacteria, poison, odor and pollution free. Process ability:no joint, easy for thermal pressing, cutting, gelatinizing, joint and etc. Shock-proof: high resilience, anti-tension and flexibility, with sound shock-proof/cushion performance. Thermal insulation :superior thermal insulation against cold and insulation. Sound -proof: sealing size and superior sound proof
