Sipchem EVA

Producer: Sipchem
Polymer type EVA

EVA (Ethylene-Vinyl Acetate Copolymer) is a copolymer of PE and VAM (Vinyl-Acetate- Monomer) made in LDPE tubular or autoclave reactors with different levels of VAM from about 2% up to 40% (wt).

EVA is an elastomeric-type material, soft and flexible with good clarity, gloss, low- temperature toughness and stress-crack resistance.

General info

Increasing the level of Vinyl-Acetate in the EVA polymer gives the following change in properties :

  • More transparancy
  • Higher density
  • Higher impact strength / tear resistance
  • Softer, higher elasticity
  • Lower melting point, lower SIT
  • Easier crosslinking
  • Better permeability
  • Higher polarity
  • Increased ESCR

EVA pure or in blends with other materials is used in a wide range of applications and industries:

  • Industrial, agriculture and food blown film applications
  • Flexible profiles and tubes
  • Solar cell encapsulation
  • Wide range of compounds as also for Wire & Cable applications
  • Foams for shoes, building and protection
  • Hot-Melt-Adhesives
