1, widely used in foamed shoe material, functional shed film, packaging mold, hot melt adhesive, wire and cable and toys and other
fields.
2, ethylene acetate content in 5%~10% EVA products for elastic film;
3, ethylene acetate content in 20~28% EVA, mainly used in hot melt adhesives and coating products;
4, vinyl acetate content in 5%~45%, the main products for film (including agricultural film) and sheet, injection molding, molding
products, foam products, hot melt adhesives.
(1) Foam shoe material. Shoe material is the most important application field of EVA resin in China. In the EVA resin used in shoe
materials, the vinyl acetate content is generally 15% to 22%. Because EVA resin blended foam products have soft, elastic, chemical
corrosion resistance and other properties, it is widely used in the middle and high grade travel shoes, hiking shoes, slippers,
sandals soles and interior materials. In addition, this material is also used in the field of sound insulation boards, gymnastics
MATS and seals.
(2) Thin film. The main use of EVA film is the production of functional shed film. Functional shed film has high weather
resistance, anti-fogging and insulation properties, because polyethylene does not have polarity, even if a certain amount of
anti-fogging agent is added, its anti-fogging performance can only be maintained for about 2 months; The addition of a certain
amount of EVA resin made of the shed film, not only has a higher light transmittivity, and anti-fogging performance is also
greatly improved, generally more than 4 months. In addition, EVA can also be used to produce packaging film, medical film,
laminated film, casting film and so on.
(3) Wire and cable. With the continuous development of computer and network engineering, more and more people use halogen-free
flame retardant cables and silane cross-linked cables for the safety of computer rooms. Because EVA resin has good packing
tolerance and crosslinking, it is used more in halogen-free flame retardant cables, semiconductor shielded cables and two-step
silane crosslinked cables. In addition, EVA resin is also used to make some special cable sheathing. EVA resin used in wire and
cable, vinyl acetate content is generally 12% to 24%.
(4) Toys. EVA resin also has more applications in toys, such as children's wheels, seat cushions and so on.
(5) Hot melt adhesive. Hot melt adhesive with EVA resin as the main component, because it does not contain solvents, does not
pollute the environment and has high safety, it is very suitable for automated production line, so it is widely used in wireless
book binding, furniture edge sealing, automobile and household appliances assembly, shoe making, carpet coating and metal
anti-corrosion coating.
(6) Others. EVA resin is also widely used in ink, luggage, bottle cushion cover and other fields, and it is estimated that EVA
resin consumption in these aspects is not less than 15 kt.
