Ethylene-vinyl Acetate Resin, referred to as EVA, is a thermoplastic resin made by copolymerization of ethylene and vinyl acetate. EVA resin is an ethylene-vinyl acetate copolymer, and the general vinyl acetate (VA) content is 5% to 40%. Compared with polyethylene, EVA Ethylene Vinyl Acetate has added vinyl acetate monomer into the molecular chain, which reduces the high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. It is widely used in foaming shoe materials, functional greenhouse films, packaging films, hot melt adhesives, wires and cables, as well as toys. In general, the performance of EVA resin mainly depends on the content of vinyl acetate in the molecular chain.
Foamed shoe materials. In the EVA resin used in shoe materials, the vinyl acetate content is generally 15% to 22%. Because EVA resin blended foam products have the properties of softness, good elasticity, and chemical corrosion resistance, they are widely used in the soles and interior materials of mid-to-high-end tourist shoes, mountaineering shoes, slippers, and sandals. In addition, this material is also used in the fields of sound insulation boards, gymnastics mats, and sealing materials.
Film. The main use of EVA film is to produce functional shed film. Functional shed film has high weather resistance, anti-fog and thermal insulation properties. The shed film made by adding a certain amount of EVA resin not only has a high light transmittance, but also has a greatly improved anti-fog performance, which can generally exceed 4 months. In addition, EVA can also be used to produce packaging films, medical films, laminated films, casting films, etc.
Wires and cables. With the continuous development of computer and network engineering, people are increasingly using halogen-free flame-retardant cables and silane cross-linked cables for the safety of computer rooms. Since EVA resin has good filler tolerance and cross-linking properties, it is widely used in halogen-free flame-retardant cables, semiconductor shielded cables and two-step silane cross-linked cables. In addition, EVA resin is also used to make the sheath of some special cables. The vinyl acetate content of EVA resin used in wires and cables is generally 12% to 24%.
Toys. EVA resin is also widely used in toys, such as child wheels, seat cushions, etc.
Hot melt adhesive. Hot melt adhesive with EVA resin as the main component does not contain solvents, does not pollute the environment and has high safety. It is very suitable for automated assembly line production. Therefore, it is widely used in book wireless binding, furniture edge banding, automobile and household appliance assembly, shoemaking, carpet coating and metal anti-corrosion coating.
The vinyl acetate content of industrial EVA copolymer is 5% to 95%, and the performance of each variety varies greatly. Generally, as the vinyl acetate content increases, the crystallinity, hardness, rigidity and heat deformation temperature gradually decrease. Meanwhile, the gloss, transparency, impact resistance, flexibility, stress cracking resistance, solubility in solvents, heat shrinkage and heat welding properties are improved to varying degrees.
EVA resin with a vinyl acetate content of 5% to 15%. Compared with low density polyethylene, its appearance and physical and mechanical properties are very similar, but its transparency, flexibility, heat welding and stress cracking resistance have been significantly improved. The processing method is also the same, suitable for agricultural film, heat shrink film, various composite films and general packaging films, and can also be used as cable sheaths.
EVA resin with a vinyl acetate content of 15% to 40%. It is flexible and elastic, and can be used as soles, sealing strips, cable products and foam plastic products. It is mixed with paraffin and used as a papermaking chemical. It also has good bonding properties with many materials and is widely used to prepare various hot melt adhesives and other types of adhesives for book binding and packaging sealing.
EVA elastomer with a vinyl acetate content of 40% to 50%. It can be used in the cable industry after cross-linking. Some factories in Western Europe graft vinyl chloride with it to improve the impact resistance of rigid polyvinyl chloride.
EVA emulsion with a vinyl acetate content of 70% to 95%. It is generally sold directly in the form of emulsion. It is used to prepare various coatings, adhesives and as paper and fabric coatings.
