What Is EVA Foam?

EVA foam material is a common name in the industry, the chemical name of EVA is: ethylene-vinyl acetate copolymer, and the English name is: ethylene-vinyl acetate copolymer. EVA is a commonly used foam material, which has a wide range of applications, including packaging, electronics, machinery, automobiles, aviation, home appliances, digital and other fields.

Features of EVA foam material:

The finished products processed by EVA foam materials generally have the characteristics of good cushioning, shock resistance, heat insulation, moisture resistance and chemical corrosion resistance, and the products are non-toxic, which is a very reliable material.

1. EVA foam is a closed bubble structure, which does not absorb water, is moisture-proof, has good water resistance and good sound insulation effect.

2. Resistant to seawater, grease, acid, alkali and other chemicals.

3. EVA foam is a very popular processing material, which is easy to be processed by hot pressing, cutting, gluing, laminating, etc.

4. High resilience and tension resistance, strong toughness, good shockproof and cushioning performance.

5. Excellent heat insulation, heat preservation and low temperature performance, and can withstand severe cold and exposure.

The precision of EVA foam material is high, and it can also be cut after the whole piece is processed, which is not easy to delaminate and can be well dissolved with self-adhesive, and basically will not produce non-sticky glue.

Classification of EVA foam materials

It is mainly classified according to the color, function, processing and foaming method of EVA foam material:

1. Color: EVA foam can be customized and processed into a variety of colors, commonly used is black and white; Others are colored, camouflage, etc.

2. Function: According to the different characteristics of EVA foam, it can be divided into high elasticity, anti-static EVA, fireproof, shockproof, moisture-proof, etc.

3. Foaming method: EVA foam can be divided into closed-cell foam and open-cell foam.

4. Product category: Due to the wide range of EVA applications, general processed products can be divided into lining, inner support, special-shaped EVA, foot pads, rubber pads, liners and foam and other products.

5. Processing technology: sheet, coil, gluing, adhesive, molding, punching, embossing, engraving, etc.
