Eva
Eva is produced by the copolymerization of ethylene (E) and ethylene acetate (VA).Eva is characterized by good flexibility, rubber-like elasticity, good flexibility at -50℃, good transparency and surface gloss, good chemical stability, good anti-aging and ozone strength, and non-toxicity.Good mixing property with filler, good coloring and molding.Eva can be injection molding, extrusion, blow molding, calendering, rolling plastic vacuum thermoforming, foaming, coating, heat sealing, welding and other molding processes, can be used as building materials for waterproof, arson, sound insulation and other functions.
The sponge
Sponge is mostly synthesized from polyisocyanate and polyol as raw materials, the basic reaction is polyol and polyisocyanate production of polyurethane reaction, commonly used sponge science is called polyurethane soft foaming rubber, polyurethane is the most common in life a kind of polymer material, widely used in the production of various sponge products.And shock absorbers, anti - friction use of elastic materials.
How do you distinguish between a sponge and an Eva?
1. It can be distinguished with the naked eye. Sponges are generally yellowish, very elastic and relatively lighter than these two.Eva is a bit hard, generally black, is the heaviest, no matter how you press the sponge points to restore the original state.
