The benefits of eva insoles?
xinstMay 09, 2020
EVA insoles have various colors and hardness, water resistance: closed cell structure, no water absorption, moisture resistance, good water resistance. Corrosion resistance: resistant to seawater, grease, acid, alkali and other chemicals, antibacterial, non-toxic, tasteless, and pollution-free. Q Processability: No joints, and easy to process such as hot pressing, cutting, glueing, laminating, etc. Anti-vibration: high resilience and tensile strength, strong toughness, and good shock / buffer resistance. Thermal insulation: thermal insulation, thermal insulation and low temperature performance are excellent, can withstand severe cold and exposure. Sound insulation: closed cell, good sound insulation effect.
EVA insole is a fortune rose insole made by processing EVA as the main material, which is widely used in the shoemaking industry and insole market. EVA insoles are usually made of EVA as the main material of insoles, combined with fabrics, leather, and other fabrics.
EVA is an ethylene-vinyl acetate (vinyl acetate) ester copolymer. It is produced by copolymerizing ethylene (E79fa5e98193e59b9ee7ad9431333431376633) (E) and vinyl acetate (VA). The English name is: Ethylene Vinyl Acetate, referred to as EVA, or E / VAC . Generally, the content of vinyl acetate (VA) is 5% -40%. Compared with polyethylene, EVA introduces vinyl acetate monomer in the molecular chain, thereby reducing the crystallinity, improving flexibility, impact resistance, filler compatibility and heat sealing performance. In general, the performance of EVA resin mainly depends on the content of vinyl acetate in the molecular chain. Because the proportion of constituent components can be adjusted to meet different application needs, the higher the content of vinyl acetate (VA content), the greater the transparency, softness and toughness.
