Ethylene vinyl acetate (EVA) is the copolymer of ethylene and vinyl acetate. Itâs an extremely elastic material that can be sintered to form a porous material similar to rubber, yet with excellent toughness. The porous elastomeric material is three times as flexible as low-density polyethylene (LDPE), showing tensile elongation of 750% with a peak melting temperature of 250Â°F (96Â°C).
