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
