Eva material is an extremely common material, a kind of midsole material that is more common in daily life. The finished product made of it has good flexibility, shock resistance, non-slip, and strong resistance to pressure, such as our common EVA slippers, Cotton shoes, EVA mobile phone protective cover, EVAipad protective cover, etc.
The polymerization method uses high-pressure bulk polymerization (for plastics), solution polymerization (PVC processing aid), emulsion polymerization (adhesive), and suspension polymerization. Emulsion polymerization is used for vinyl acetate (VA) content higher than 30%, and high-pressure bulk polymerization is used for low vinyl acetate content.
EVA sole refers to a sole made of EVA material. EVA soles have high resilience and tension resistance, high toughness, good shock resistance, cushioning properties, excellent heat insulation, heat preservation and cold protection and low temperature performance, resistance to severe cold and exposure, airtight cells, good sound insulation, airtight cell structure, no It has good water absorption, moisture resistance and water resistance, resistance to sea water, grease, acid, alkali and other chemical corrosion, antibacterial, non-toxic, tasteless, and pollution-free.
