弹性透明塑胶粒EVA (CAS No.None)
- 中文别名
- 乙烯-醋酸乙烯共聚物；EVA树脂；EVA胶粒
- 英文名称
- Ethylene-Vinyl Acetate Copolymer (EVA)
- 分子式
- (C2H4)x(C4H6O2)y
- 所属类别
- 塑料橡胶
- 物化性质
- EVA具有优异的耐低温性能，热分解温度约230℃。随着分子量增大，软化点升高，加工性和表面光泽度下降，但强度、冲击韧性和耐环境应力开裂性提高。耐化学药品和耐油性较PE、PVC稍差，且随醋酸乙烯含量增加变化更明显。相比PE，EVA在弹性、柔性、光泽性、透气性方面显著改善，填料受容性大，可通过加入增强填料弥补力学性能下降。
- 密度
- 0.92~0.95 g/cm³

Product Name:Ethylene-Vinyl Acetate Copolymer (EVA)
English Name:Ethylene-Vinyl Acetate Copolymer (EVA)
CAS No.:24937-78-8
Aliases:Ethylene Vinyl Acetate Resin, EVA Resin, EVA Pellets
Molecular Formula:(C2H4)x(C4H6O2)y
Physical Properties:EVA exhibits excellent low-temperature resistance with a thermal decomposition temperature of approximately 230°C. As molecular weight increases, the softening point rises while processability and surface gloss decrease, but strength, impact toughness, and environmental stress cracking resistance improve. Its chemical resistance and oil resistance are slightly inferior to PE and PVC, with the difference becoming more pronounced as vinyl acetate content increases. Compared with PE, EVA shows significant improvements in elasticity, flexibility, gloss, and air permeability, and has high filler acceptance, allowing the use of reinforcing fillers to compensate for reduced mechanical properties.
Uses:EVA is widely used in foamed shoe materials, packaging films, hot-melt adhesives, and wire and cable insulation. It can also be modified through grafting or partial alcoholysis to develop new properties and expand its range of applications.
Technical Specifications:
Vinyl acetate (VA) content: 10%-40%, exhibiting typical plastic characteristics below 20%
Density: 0.92-0.95 g/cm³
Thermal decomposition temperature: approximately 230°C
Vicat softening point: approximately 40-70°C, increasing with molecular weight
Melt flow index (MFI): adjustable by grade, typically 2-20 g/10min
