Evatane® key properties

Evatane® resins are elastic, polar and highly transparent. They exhibit high filler acceptance and adhesion onto various substrates (PE, PS, PET, PVC, PP...). Evatane® resins are easy to process, highly compatible with resins & waxes.

Structural Properties

Key characteristics:  

Comonomer content: 18% to 42% by weight
Melt flow index: 2.5 to 800 g/10mn (190°C - 2,16 kg)

 

The main properties of Evatane® copolymers depends on Molecular weight and Vinyl Acetate content.

 

Increase vinyl acetate content increases:

And reduces
  • Transparency
  • Adhesion
  • Solubility
  • Toughness
  • Compatibility with polar products
  • Filler acceptance
  • Flexibility
  • Cristallinity
  • Melting point
  • Softening point
  • Rigidity
  • Hardness

Compatibility

Evatane® is a polar copolymer. The polarity allows a good compatibility with other polymers and a large range of raw materials for hot melt adhesives such as tackifiers, waxes and plasticizers.

Adhesion

Evatane® copolymers are used for films and sheets extrusion either as tie layer (mainly for PE, PS, PET, PVC and PP) or as sealing layer due to their excellent hot tack properties. Evatane® (VA content > 40%) is also used for printing inks to promote adhesion to the substrate.

Processing

Evatane is easy to process onto existing equipments:

injection moulding, blow moulding, blown and cast film extrusion as well as tube, cable and profile extrusion.
