The difference between packaging materials EPE, EVA, sponge

EPE (Expandable Polyethylene), is made of polyethylene, also known as EPE. Non-cross-linked closed-cell structure, which is based on low-density polyethylene (LDPE) as the main raw material extruded polyethylene foam products generate high, it is produced by low-density polyethylene resin produced by physical foaming numerous independent bubbles composition. To overcome the ordinary foam rubber brittle deformation, the shortcomings of poor response. Having impermeable to moisture, vibration, noise, thermal insulation, good plasticity, toughness, recycling, environmental protection, strong anti-collision and many other advantages, also has good chemical resistance.
 
Sponge mostly by the polyisocyanate and polyol as a raw material to synthesize the basic reaction is the reaction polyol with an isocyanate to produce polyurethane, commonly used sponges school called polyurethane soft foam rubber, polyurethane is the life of the most common type of polymer material, widely used in the production of "SpongeBob" products. As well as shock absorbers, anti-friction purposes of elastic material.
 
EVA is abbreviated as EVA prepared from ethylene (E) and vinyl acetate (VA) copolymer. EVA is characterized by good flexibility, rubber-like elasticity at -50 ℃ to have good flexibility, transparency and surface gloss, good chemical stability, anti-aging and ozone resistance strength , non-toxic. Mixing with the filler is good, good coloring and forming. EVA can be injection molding, extrusion, blow molding, calendaring, rotational vacuum thermoforming, foam, coating, sealing, welding, forming, materials used as water, fire, noise and other effects can be used as.
