PP with glass fiber: high rigidity and strong mechanical resistance

Tecnoprene ® (PP/GF)

Glass Fibre reinforced Polypropylene
Tecnoprene® represents a family of products based on PP reinforced with chemically bonded glass fiber, which have been studied for applications requiring high rigidity and strong mechanical resistance also at high temperatures.
The chemical bond between PP and GF guarantee a high impact resistance, improved mechanical properties and better performances under tensile strength.
Special grades have been developed for applications which imply contact with detergents.
The high thermal performances and considerable impact resistance in different operating conditions make Tecnoprene® especially suitable for various technical applications.


  • Bumpers, under-the-hood parts


  • Outer casings of small household appliances, washing machine tub, refrigerator trays and shelves.


  • Plates for electrical switches, engine cover plates, electrical condenser housings.


Tecnoprene® can be co-moulded with the following elastomeric compounds of SO.F.TER. product range: Forprene® (TPV), Laprene® (SEBS), Sofprene® (SBS).
The Tecnoprene® range includes grades for:
  • Injection moulding
  • Extrusion
  • Blow moulding
  • Rotational moulding.
Tecnoprene® is a fully recyclable material and it can be reused after regrinding. The user shall always carry out his own tests and analyses in order to verify that the compound obtained by mixing virgin and reground granules is suitable for the specific application and that its properties meets the requirements.
