EVA is referred to as EVA, and the general (VA) content is 5% to 40%. Compared with polyethylene, EVA is widely used in the molecular chain due to the introduction of monomer, which reduces the high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. Foaming shoe material, functional shed film, packaging film, hot melt adhesive, wire and cable and toys and other fields. Features of EVA plastic: Water resistance: closed cell structure, non-absorbent, moisture-proof, good water resistance. Corrosion resistance: Resistant to seawater, grease, acid, alkali and other chemicals, antibacterial, non-toxic, odorless, and pollution-free. Processability: no joints, and easy to process such as hot pressing, cutting, gluing, laminating, etc. Anti-vibration: high resilience and tensile strength, high toughness, good shock-proof and cushioning performance. Thermal insulation: excellent thermal insulation, thermal insulation and cold protection and low temperature performance, can withstand severe cold and exposure. Sound insulation: closed cells, good sound insulation.
