Application of ethylene-vinyl acetate copolymer (EVA) in hybrid composite materials-Shanghai Beite Chemical Co., Ltd.

Ethylene-vinyl acetate copolymer (EVA) is a general-purpose polymer that is flammable and has no irritating burning smell.

The application of ethylene-vinyl acetate copolymer (EVA) in hybrid composite materials is as follows:

EVA copolymer can withstand high doses of fillers and can be used with Different organic or inorganic compounds can be blended well to form composite materials for various purposes or as carriers for masterbatch, giving them a wider range of uses.

The main use of EVA composite materials is to make wires and cables. Add a large amount of superconductor and electrostatic dispersion carbon black, flame retardants to inhibit the burning of insulators, and other fillers and additives into EVA. And after steam and chemical vulcanization process or radiation treatment, it can be made into foam or sheath for insulation protection.

When EVA is used as a color masterbatch carrier, the amount of dyes and additives (UV stabilizer) added can be as high as 50% to 80%. EVA’s ability to withstand additives is directly proportional to the VAc content in the resin. As the VAc content increases, the additive absorption capacity increases accordingly, and thus a color masterbatch with a high dosage of additives can be produced.

EVA is also an excellent modifier. It can be blended with PE, PP and PVC to produce a series of plastic modified products with a wide range of applications. The addition of EVA makes the plastic base material more Flexibility, toughness, stress crack resistance and bonding properties are improved.
