The professional vocabulary people encounter when buying shoes such as garden shoes and slippers is daunting, because there are too many footwear terms that confuse people. What exactly is EVA? What is the relationship between this material and garden shoes and slippers? What kind of shoes should people choose?
Today, I will explain the application and basic knowledge of EVA in footwear manufacturing with you.
What is EVA?
EVA (ethylene-vinyl acetate copolymer) plastic raw material, abbreviation: EVA, refers to ethylene-vinyl acetate copolymer. EVA can be used to produce materials with flexibility and softness similar to rubber. EVA is very useful in manufacturing, well beyond footwear. It is widely used in foaming shoe material, functional shed film, packaging film, hot melt adhesive, wire and cable and toys, and other fields. Shoe material is the main application field of EVA resin in China. In the EVA resin used in footwear, the content of vinyl acetate is generally 15% ~ 22%. Due to its soft, elastic, and chemical corrosion resistance, EVA resin blends and foams are widely used in the soles and interior materials of middle and high-grade traveling shoes, hiking shoes, slippers, and sandals.
Application of EVA in the footwear industry
EVA is the most common cushioning material in the midsole of athletic shoes. EVA is mainly used on the midsole (or the layer between the outsole and the upper). The midsole is the part responsible for cushioning, helping to comfort the foot, and protecting the foot.
Today, the use of EVA in the footwear industry is more diverse than before, and advances in materials have made EVA a very popular part of footwear.
EVA is widely used in the manufacture of garden shoes and slippers because EVA is water-resistant and oil-resistant. It is considered safe and environmentally friendly due to its antibacterial and non-toxic properties. Advantages of EVA: lightweight, good elasticity, good flexibility, not easy to wrinkle, with excellent coloring, suitable for various climates.
