In the context of new technical developments we have extruded a white coloured PP-HT material, which is particularly suitable for applications in the chemical industry and for thermally demanding applications.

GEHR PP-HT® is a new material that has a heat deflection temperature (HDT/B=133 °C) which is approximately 40 °C higher than that of standard PP without losing its high chemical resistance. The melting point of PP HT is approximately 165 °C. It was possible to significantly enhance the mechanical properties of this homopolymeric material, which expands the field of application for the use of a polyolefin.


Product range

  • High chemical resistance, as typical of PP
  • Enhanced elastic modulus (approx. 2300 MPa) and yield strength (approx. 40 MPa)
  • Heat deflection temperature is approximately 40 °C higher than that of standard PP
  • Raw material complies with FDA and 10/2011/EC requirements for food contact applications


  • Wherever mechanical properties are required that are superior to those of standard PP, or
  • Where enhanced thermal properties are indispensable and – until now – alternative solutions had to be found.
