Covering Process

Coextrusion covering process technology is used to bring additional properties to monolayer tubes (based on HDPE or XPE) such as:

  • Barrier
  • Mechanical resistance (elongation at break, modulus, etc.)
  • Abrasion resistance

Typical applications include:

Direct Coextrusion process (3or5 extruders):

  • Hot water pipe
  • Heating tubes

Direct Coextrusion technology is used to develop multilayer tubes in a one step process.

Typical applications include :

  • Hot water pipe
  • Heating tubes
  • Packaging tubes
