PP-R systems

Polypropylene (PP) as pipe raw material, is in use for pipeline production long time, and have approved their performance for pressure and non pressure application.

For pressure pipe are in use:

  • PP-R (polypropylene random copolymer)

For non pressure application, the latest polypropylene raw material PP HM – high impact, high molecular – PPHM material or

  • Polypropylene block copolymer

This group of materials shows very high impact resistance, high temperature stability, and ultra high stiffness, what classify this material as dominant material for non pressure pipe application, like sewage and drainage.
