Ethylene-vinyl Acetate(EVA) cases introduction

 

  • Whats EVA material?
  • EVA features & functions?
  • EVA cases application?

 

 1. Whats EVA material?

 

 

 

 

 

Ethylene-vinyl Acetate(EVA)

 

Chemical formula

(C2H4)n(C4H6O2)m

Other names

Poly(ethylene-vinyl acetate);

Poly(ethylene-co-vinyl acetate);

Polyethylene-vinyl acetate copolymer

Abbreviations

EVA; PEVA

 

Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene., is an elastic polymer material that is similar to rubber. EVA usually contains no more than 40 percent vinyl acetate by weight, with the rest of the polymer being ethylene. It is resistant to cracks and ultraviolet radiation. (Wikipedia)

 

2. EVA features & functions?

soft and extremely elastic yet tough

competitive with rubber and vinyl in many electrical applications

good clarity and gloss with little or no odor

Ethylene vinyl acetate (EVA) is the copolymer of ethylene and vinyl acetate. It’s an extremely elastic material that can be sintered to form a porous material similar to rubber, yet with excellent toughness. The porous elastomeric material is three times as flexible as low-density polyethylene (LDPE), showing tensile elongation of 750% with a peak melting temperature of 250°F (96°C).

This flexible porous plastic material has good barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to ultraviolet radiation. Porous EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications.

3. EVA (Ethylene Vinyl Acetate) Cases
