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.

The orthodontic mouth guard designed by human oral structure design which is toxic-less and tasteless,

no breathe barrier when they close your mouth.It helps the wearers make corrections to their teeth.

such as wide space problem between teeth,canine teeth, gagtooth problem.

The material we use is FDA TPE,which is long-range elasticity,high strength,touching soft,

temperature tolerance is good,widely used in our daily life.

Precautions:Don’t bite,just relax you mouth.

1.No put the brace in boiling water.

2.It’s the ordinary that someone will be drooly,nausea,toothache phenomenon happened for the first time wearing.

3.Have the brace washed after using for 3 minutes.

4.The wearing time is about 2h daylight, 8h at night.

Usage:

1.Put the mouth guard in 60-70℃ water about 50 seconds before using and after using.

2.Put into your mouth with right way.

3. Don’t bite or chew the brace hard.

4.After using, keep it dry and put it in the storage box.
