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.

Application fields of EVA (ethylene - vinyl acetate copolymer) :

I. EVA products with ethylene acetate content of 5%~10% are elastic films, etc.

EVA with ethylene acetate content of 20~28%, mainly used for hot-melt adhesives and coating products;

The content of ethylene acetate is 5%~45%, the main products are film (including agricultural film) and sheet, 

injection molding, molding products, foaming products, hot-melt adhesives, etc.

1.EVA material properties

Water resistance: sealed bubble structure, non - absorbent, moisture resistance, good water resistance. 

A) Corrosion resistance: seawater, oil, acid, alkali and other chemicals corrosion resistance, 

antibacterial, non-toxic, tasteless, no pollution. 

B) Machinability: no joint, and easy to hot-pressing, cutting, gluing, fitting and other processing.

C) Shockproof: high resilience and tensile strength, high toughness, and good shockproof/buffering performance. 

D) Thermal insulation: excellent performance in heat insulation, cold preservation and low temperature, 

and resistance to cold and sunlight. 

E) (5) Sound insulation: Closed bubble hole, sound insulation effect is good.

2. Store cautions

Store in a cool, ventilated warehouse.Keep away from fire and heat.Should be stored separately with oxidizer, 

alkali, avoid mixing storage, equipped with the corresponding variety and quantity of fire equipment.

3. Main USES

It can also be used for packaging film, gasket, medical equipment, 

hot-melt adhesive, cable insulation layer and so on.
