Features Of EVA Particles:
1. Water resistance: closed cell structure, non-absorbent, moisture-proof, good water resistance.
2. Corrosion resistance: resistant to seawater, oil, acid, alkali and other chemical corrosion, antibacterial, non-toxic, tasteless, and pollution-free.
3. Processability: no joints, and easy to process such as hot pressing, cutting, gluing, laminating, etc.
4. Anti-vibration: High resilience and tensile strength, high toughness, good shock-proof and cushioning performance.
5. Heat preservation: heat insulation, heat preservation, cold protection and low temperature performance are excellent, and can withstand severe cold and sun exposure.
6. Sound insulation: closed cells, good sound insulation effect.
Applications:
1. Widely used in foamed shoe materials, functional film, packaging film, hot melt adhesives, wires and cables, toys and other fields.
2. EVA products with a vinyl acetate content of 5%~10% are elastic films, etc.;
3. EVA with a vinyl acetate content of 20~28% is mainly used for hot melt adhesives and coating products;
4. The content of vinyl acetate is 5%~45%. The main products are films (including agricultural films) and sheets, injection molding, molding products, foaming products, hot melt adhesives, etc.
(1) Foam shoe material. In the EVA resin used in shoe materials, the vinyl acetate content is generally 15% to 22%. Because EVA resin blended foam products have softness, good elasticity, and chemical corrosion resistance, they are widely used in the soles and interior materials of mid-to-high-end travel shoes, hiking shoes, slippers, and sandals. In addition, this material is also used in the field of sound insulation panels, gym mats and sealing materials.
(2) Film. The main purpose of EVA film is to produce functional greenhouse film. Functional shed film has high weather resistance, anti-fog drop and thermal insulation properties. Since polyethylene is not polar, even if a certain amount of anti-fog drop agent is added, its anti-fog drop performance can only last for about 2 months; while 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 last for more than 4 months. In addition, EVA can also be used to produce packaging films, medical films, laminated films, casting films, etc.
(3) Wire and cable. Because EVA resin has good filler tolerance and crosslinkability, it is widely used in halogen-free flame-retardant cables, semiconductor shielded cables and two-step silane crosslinked cables. In addition, EVA resin is also used to make sheaths for some special cables. The EVA resin used in wire and cable generally has a vinyl acetate content of 12% to 24%.
(4) TOYS. EVA resin is also widely used in toys, such as children's wheels, seat cushions, etc.
(5) Hot melt adhesive. The 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, is very suitable for automated assembly line production, so it is widely used in perfect book binding, furniture edge banding, automobiles and household appliances Assembly, shoemaking, carpet coating and metal anti-corrosion coating.
(6) Others. EVA resin is also widely used in the fields of ink, luggage, wine bottle cover and so on.
