Product Introduction:

Ethylene-vinyl acetate copolymer (EVA) is obtained by copolymerizing ethylene and vinyl acetate in different ratios. E in EVA represents the ethylene component, and VA represents the vinyl acetate component. Its performance is closely related to the content of vinyl acetate (VA).

According to the different VA content, it can be divided into three categories:

  1. VA content of 5%-40% is called EVA plastic, which is mainly used for polyethylene modification, manufacturing wire and cable, film and other molded products and mixtures, etc.
  2. VA content of 40%-90% is called EVA rubber, which is mainly used in rubber, cables and automotive industrial parts.
  3. VA content higher than 90% is called polyvinyl acetate emulsion, mainly used in adhesives, coatings, etc.

Product function:

  1. Film, Film is one of the most important uses of Ethylene-vinyl acetate copolymer. The VAc content of film grade EVA resins is typically 126-15%, with peaks below 20%. Because the VAc content is too high, the resin has a high viscosity and is not suitable for blowing films. EVA and gold-plated polyester films are co-extruded or laminated to replace tin cans, medical films and other applications with stringent requirements.
  2. Adhesives and coatings, Hot melt adhesives are one of the most important applications of Ethylene-vinyl acetate copolymer. It is characterized by excellent mechanical properties and mechanical stability, high viscosity, controllable particle size, creep resistance and heat sealability. There is a good balance between them and Good wet adhesion and fast curing speed, special adhesion to difficult-to-bond film substrates.
  3. Molded and extruded products, Ethylene-vinyl acetate copolymer EVA molded and extruded products typically use copolymers with a VAc content of 9% to 18%, which offers flexibility and toughness. Ethylene-vinyl acetate copolymer can be extruded into highly transparent hoses and rigid tubing for blood transfusion, blood pressure transfer, beverage transfer and construction mortars, as well as hoses for dust collection and water supply systems.
  4. Foamed plastic EVA with a VAc content of 12% to 16% is used to manufacture high-speed closed-celled foams. Foamed plastic is used as a material for insulation, impact resistance, and packaging in industry, architecture, and aquaculture, as it has low thermal insulation, heat retention, impact resistance, and low compression deformation, excellent elasticity, and excellent weather resistance and secondary processability. Currently, it is used for lifesaving buoys on ships and locomotive rooms.
  5. It also began to be used for building insulation. In the footwear industry, EVA with 10%-20% VAc content can be used as the main raw material alone or in combination with LDPE, NR, BR, EPDM, CPE (Chlorinated Polyethylene) to make microporous shoes. bottom piece.
  6. Blended Composite Ethylene-vinyl acetate copolymer Copolymers have a wider scope as they can withstand high capacity fillers and mix well with a variety of organic or inorganic compounds, allowing them to be formulated as carriers for composites or masterbatches for a variety of purposes. use.
  7. The main purpose of EVA composite materials is to make wires and cables. EVA contains a large amount of carbon black for superconductors and static dissipation, flame retardants that suppress combustion of insulators, and other fillers and additives. And it can be made of foam or sheath for thermal protection after steam and chemical vulcanization or radiation treatment.
  8. Ethylene-vinyl acetate copolymer is also an excellent modifier and can be blended with PE, PP and PVC to manufacture a range of plastic modification products for a wide range of applications. The addition of EVA improves the flexibility, toughness, stress cracking resistance and bonding properties of the plastic base material.
  9. Petroleum Crude Oil and Oil Additives, Ethylene-vinyl acetate copolymer with high VAc content can be used as an additive in petroleum products to significantly lower the freezing point of fuels. EVA can be used as crude oil wax inhibitor and fluidity improver and other oil additives, and can improve low temperature fluidity by lowering the freezing point of crude oil.
  10. Other aspects One of the newest uses for EVA is foundry production and powder metallurgy. If EVA is used as the veneer material for the inner surface of the mold, sand can be completely hardened without external adhesives, and the casting surface is smooth and easy to process.
