EVA

EVA (Ethylene-Vinyl Acetate Copolymer) is a copolymer produced by combining VAM (vinyl acetate monomer), varying between 2% and 40%, with PE (polyethylene) by autoclave or LDPE tubular process.

EVA is an elastomeric material that is soft, flexible, has good transparency and is shiny. It has good hardness at low temperatures and cracking properties against pressure.

When the vinyl acetate content of EVA increases:
Transparency increases
Density increases
Impact strength and tear resistance increases
It is softer and more elastic
It has a lower melting point
Can be cross-linked more easily
Its permeability increases
Polarity increases
ESCR increases

EVA in its pure form or mixtures with different substances is used in a wide variety of industries and applications:
Industrial agriculture and food blown film applications
Flexible profiles and pipes
solar cell encapsulation
Wide range of compounds including cable applications
Shoe, building and protection foams
Hot-Melt adhesives
