Eva is not foam or rubber material; it is a plastic made from the copolymerization of ethylene and vinyl acetate.
During the material agglomeration process, a high-pressure bulk polymerization method is employed. Foam agents, zinc stearate, foaming aids, and other functional materials are added, then processed through密炼 (intensive mixing),练胶 (compounding), and sheet extrusion. Subsequently, they are formed into foam at 170 degrees Celsius under high pressure using a large-scale hydraulic foaming machine. Finally, the edges are trimmed or seamless joints are made to produce the required EVA foam materials, including EVA sheet materials, EVA rolls, antistatic EVA, and fire-resistant EVA.
Characteristics of Eva material:
EVA materials exhibit excellent water resistance due to their sealed pore structure, which does not absorb moisture and provides good moisture-proof properties.
2. Eva materials are also highly resistant to corrosion, preventing chemical reactions with substances like oils, acids, alkalis, and seawater. Additionally, they are non-toxic and odorless, making them extremely safe for use.
3. Eva material boasts good resilience and tensile properties, along with excellent flexibility, offering shock absorption and cushioning effects. Moreover, due to its sealed cell structure, it also provides good soundproofing capabilities.
4. EVA, or ethylene-vinyl acetate copolymer, is a common material made by copolymerizing ethylene and vinyl acetate. EVA materials are soft, shockproof, and pressure-resistant, often used in the production of slippers, cotton shoes, phone cases, and earphone cases, among other products. The soles of finished footwear have strong thermal insulation, are resistant to acidic and alkaline chemical corrosion, and are antibacterial and odorless, offering good quality.
