Ethylene-vinylacetate copolymer EVA is the most important and the most widely used ethylene copolymer.

Why EVA?

Product characteristics enhancement

Commercial types contain 10-60% of vinylacetate (VAC). By increasing the VAC share, the crystallinity is decreased while surface brilliance, flexibility, and elasticity is improved. Chemical resistance is also enhanced substantially.

Solubility and stability

EVA is soluble in ketones, aromatic, and chlorinated hydrocarbon and is stable in oils and greases.

Simple processing

EVA with a 5-15% VAC share has similar characteristics to LDPE, though processing is easier difficult and does not shrink as much. Therefore, it enables for easier processing without unnecessary complications.

Multi-purpose application

Ethylene vinylacetate can be processed effectively using various processing procedures. It is suitable for extrusion, injection moulding, as well as thermoforming.

The main advantage of EVA is the possibility of modification with various fillers and additives, thus enhancing the basic polymer characteristics and increasing its applicability.
