EVA: It is an environmentally friendly material, and its main components are ethylene and vinyl acetate, which are relatively harmless chemicals. PVC:PVC also has low toxicity or non-toxic environmental protection products. In some cases, PVC will contain highly toxic additives, which is not as good as EVA in environmental protection.

EVA: It is mainly composed of ethylene and vinyl acetate, and the two monomers are polymerized to form * * * polymer. PVC: Thermoplastic resin mainly polymerized from vinyl chloride monomer, also known as vinyl chloride homopolymer or vinyl chloride polymer.

EVA: It is solid at room temperature, and can be softened and sticky after heating. It is suitable for foamed products, hot melt adhesives and polymer modifiers. PVC: Natural color is light yellow, translucent, shiny, and its transparency is better than that of polyethylene and polystyrene, but slightly worse than that of polystyrene. PVC can be divided into soft PVC and hard PVC. Soft PVC is flexible, and hard PVC is high hardness.

EVA: It is often used in the midsole of sports shoes, children's toys, sports equipment and packaging materials. Because it is light, soft and has good cushioning. PVC: Because of its low cost and good mechanical properties, it is widely used in building materials (such as pipes and floors), wire and cable insulation, furniture, clothing, toys and other fields.

EVA: The price is usually higher than that of PVC, because its production cost is higher. PVC: As an economical plastic material, the price of PVC is usually low.
