EVA

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

EVA is an elastomeric material and has a soft, flexible structure.

When the vinyl acetate content of EVA increases:

Transparency increases
Density increases
Impact strength and tear resistance increase
It is softer and more elastic
Has a lower melting point
Easier to cross-connect
Permeability increases
Polarity increases
ESCR increases

EVA in its pure form or blends with different substances is used in a wide range of industries and applications:

Industrial agriculture and food blown film applications
Flexible profiles and pipes
Solar cell encapsulation
A wide range of compounds, including cable applications
Footwear, building and protection foams
Hot-Melt adhesives
