Eva material is a very common material, which is a kind of common medium bottom material in daily life. 

The finished products made with it have good softness, shock resistance, skid resistance and strong pressure resistance, 

such as our common Eva slippers, cotton shoes, Eva mobile phone protective cover, Eva iPad protective cover, etc..

Polymerization methods: High pressure bulk polymerization (for plastics), solution polymerization (PVC processing AIDS), 

emulsion polymerization (adhesives), suspension polymerization.

Emulsion polymerization was used for ethylene acetate (VA) content higher than 30%, 

and high-pressure bulk polymerization was used for ethylene acetate content lower.

EVA resilience and resistance to tension, has a good shockproof, buffer performance, heat insulation, 

excellent insulation cold and low temperature resistance, resistant to cold and exposure, airtight bubble hole, 

sound insulation effect is good, airtight bubble pore structure, non-absorbent, moisture-proof, 

good water resistance, resistance to sea water, oil, acid, alkali and other chemical corrosion, 

antibacterial, non-toxic, tasteless, no pollution.
