1, EVA features: EVA soles have high resilience and tensile resistance, high toughness, good impact resistance, excellent heat insulation and low temperature performance, cold resistance and low temperature performance, cold resistance, closed pores, good sound insulation effect, closed pore structure, no water absorption, moistureproof, waterproof, corrosion resistance to chemicals such as seawater, grease, acid and alkali, antibacterial, nontoxic, tasteless and pollution-free.
2, rubber characteristics: the advantage of natural rubber is very soft, excellent elasticity, can adapt to various sports, play a role in shock absorption, but the disadvantage is also very obvious, that is, it is not wear-resistant. Natural rubber is often used in indoor sports shoes.
Performance characteristics:
Carbon is added to ordinary rubber materials, which makes rubber more tough and wear-resistant. Most running shoes are made of this kind of rubber, and the letters BRS will be left on the back of the sole of running shoes, indicating that the outsole is made of carbon rubber.
Because vinyl acetate monomer is introduced into the molecular chain, the high crystallinity is reduced, and the flexibility, impact resistance, filler compatibility and heat sealing performance are improved. EVA is widely used in foam shoes, functional shed films, packaging films, hot melt adhesives, wires and cables, toys and other fields.
