Evatane® Key Points

Structural Properties

Key characteristics:  

Comonomer content: 18 to 43% by weight
Melt flow index:  2.5 to 800 g/10mn (190°C - 2,16 kg)

The properties of Evatane® Copolymers mainly depends on two factors:

Molecular weight and Vinyl Acetate content

Molecular weight affects the properties of EVA copolymers in the same way that it influences those of Polyethylene and many other polymers.

The progressive inclusion of Vinyl Acetate in the basic Polyethylene backbone chain has two specific effects for the properties of copolymers.

When VA content increases, this enduces the following changes of characteristics:

Processing

All traditional converting techniques used for LDPE can also be used to convert Evatane®: Injection moulding, Blow moulding, Blown and cast film extrusion as well as tube, cable and profile extrusion.

Applications

Ethylene Vinyl Acetate Copolymers have a wide variety of uses such as:
