EVA is the short name of Ethylene Vinyl Acetate Copolymer.
What will affect the EVA performance?
1, Melt Index (MI)
2, The content of VA%
When the MI is certain, the Higher of VA%, the higher of Elasticity, softness, compatibility, transparency. Otherwise,
As the MI decreases, the molecular weight increases, and the impact properties and resistance to environmental stress cracking increase.
EVA is characterized by good flexibility, rubber-like elasticity, good flexibility at -50°C, transparency and surface gloss, good chemical stability, good resistance to aging and ozone, no toxicity. Good compatibility with filler and coloring, as well as good molding processability.
