Product Details
Specification
Ethylene vinyl acetate copolymer, abbreviated as EVA. The general content of vinyl acetate (VA) is between 5% and 40%. Compared with polyethylene PE, EVA reduces high crystallinity, improves toughness, impact resistance, filler solubility, and thermal sealing performance by introducing vinyl acetate monomers into its molecular chain. It is widely used in fields such as foaming shoe materials, functional greenhouse films, packaging molds, hot melt adhesives, wires and cables, and toys.
Features:
Water resistance: closed cell structure, non absorbent, moisture-proof, and good water resistance, Corrosion resistance: resistant to chemicals such as seawater, oil, acid, alkali, etc., antibacterial, non-toxic, odorless, and pollution- free, Processability: No joints, and easy to perform processing such as hot pressing, cutting, gluing, and bonding,
Anti vibration: High resilience and tension resistance, high toughness, and excellent shock and cushioning performance,
Thermal insulation: Excellent insulation, cold resistance, and low temperature performance, resistant to severe cold and exposure to sunlight,Sound insulation: Closed bubble holes, good sound insulation effect.
