English description（英文原文，共 1533 字符）
Product Name:EVA Resin
English Name:EVA Resin
CAS No.:24937-78-8
Aliases:Ethylene-vinyl acetate copolymer, Ethylene-vinyl acetate resin
Molecular Formula:(C₂H₄)ₓ(C₄H₆O₂)ᵧ
Physical Properties:This product is an ethylene-vinyl acetate copolymer with a closed-cell foam structure. It exhibits excellent water resistance, moisture resistance, transparency and surface gloss, along with good compatibility with fillers, colorability and processability. It has good thermal stability and remains flexible at -50°C, with excellent chemical stability. It is resistant to seawater, oils, acids, alkalis and other chemical corrosion, and shows good aging resistance and ozone resistance. It is antibacterial, non-toxic, odorless and pollution-free, meeting food-contact compliance requirements. Density is 0.921 g/cm³, Vicat softening temperature is 27.0°C, melting temperature (DSC) is 47.0°C, and melt temperature must be kept below 230°C during processing.
Uses:Suitable as a blending resin and adhesive raw material, widely used in wire and cable sheathing, sealants, composite materials and adhesives. In industrial applications, it serves as a base material for hot-melt adhesives and is also used in the production of composite sheets and foamed products.
