Detailed introduction of "EVA 40L-03 antioxidant eva plastic material"

EVA(Ethylene Vinyl Acetate Copolymer) 40L-03

EVA is a copolymer of ethylene and acetic acid, Chinese chemical name: ethylene-vinyl acetate copolymer (ethylene-vinyl acetate copolymer), English chemical name: Ethylene Vinyl Acetate Copolymer. The application field of EVA is quite extensive, mainly used for shoe materials.

EVA content characteristics

It is widely used in foam shoe material, functional shed film, packaging mold, hot melt adhesive, wire and cable and toys.

1. EVA with vinyl acetate content below 5%, its main products are film, wire and cable, LDPE modifier, adhesive, etc.;< /p>

2. EVA products with vinyl acetate content of 5%~10% are elastic films, etc.;

3. EVA with vinyl acetate content of 20~28%, mainly used for hot melt adhesives and coating products

A certain melt index (MI), the higher the vinyl acetate (VA) content, the higher its elasticity, softness, compatibility, transparency, etc.; when VA When its content is reduced, its performance is close to that of polyethylene (PE), the rigidity is increased, and the wear resistance and electrical insulation are improved.

The content of VA is certain, the dissolving index (MI) increases, the softening point decreases, the processability and surface gloss are improved, but the strength will decrease, otherwise, with the MI Lowering the molecular weight increases, impact performance and environmental stress crack resistance improve.

EVA is characterized by good softness, rubber-like elasticity, good flexibility, transparency and surface gloss even at -50°C good chemical stability, anti-aging and ozone resistance. Good blendability with fillers, good colorability and good molding processability

EVA material usage

(1) Films, sheets and laminates: with sealing, adhesiveness, softness, toughness and compressibility, suitable for elastic packaging films, thermal Shrink film, agricultural film, food packaging film, laminated film, can be used as the middle layer of polyolefin laminated film.

(2) General supplies: It has the advantages of flexibility, resistance to environmental stress cracking, and good weather resistance. Electrical accessories, window sealing materials, etc.

(3) Daily groceries include sporting goods, toys, cushions, straps, sealed container covers, EVA rubber footballs, etc.

(4) Auto parts include shock absorbers, fenders, interior and exterior decoration accessories, etc.

(5) Foamed products: foamed foam slippers, sandals, building materials, etc. Injection foaming has various industrial parts, women's shoe soles, hot melt adhesives, etc.

Moulding of ethylene-vinyl acetate copolymer

EVA can be injection, extrusion, blow molding, calendering, rotomolding, vacuum thermoforming, foaming, coating, heat sealing, welding, etc.
