PP

GEHR PP-C®

is a Co-Polymer Polypropylene that offers excellent impact strength and chemical resistance as well as high mechanical and tensile strength. GEHR PP-C has good notched impact strength, is easy to weld and has an excellent resistance to stress cracking. The operating temperatures ranges from -22 °F to +190 °F.

Properties: 

  • excellent impact strength 
  • high mechanical strength  
  • high tensile strength 
  • good notched impact strength 
  • easy to fabricate and weld 
  • excellent resistance to stress cracking 
  • very good chemical resistance 
  • food safe 
  • excellent dielectric properties 
  • poor resistance to UV 
  • operating temperature range from -22 °F to +190 °F

 

Applications:

Pumps, valves, gaskets, supporting stands for the coating industry, spacer for the plating, particles for toys.

GEHR PP-H®

is a Homopolymer Polypropylene that offers slightly improved chemical resistance and upper temperature resistance as well as tensile strength and is a higher density than GEHR PP-C®

Properties:

  • excellent chemical resistance

  • improved upper temperature range

  • improved tensile strength

  • food safe

  • poor resistance to UV

  • operating temperature range from +41 °F to +212 °F

GEHR Poly Pro 30% GF (HiPro®)

is a Homopolymer Polypropylene that is reinforced with 30% glass fiber which greatly enhances mechanical properties as well as the temperature profile.  Reinforced PP has an improved dimensional stability, high tensile strength and high temperature resistance. Heat deflection temperature is +284°F at 264 psi loading.

Properties:

  • very high dimensional stability

  • very high tensile strength

  • high temperature resistance

  • heat deflection temperature (HDT/A) of +284 °F

Applications:

Pumps, valves, gaskets, supporting stands for the coating industry, spacer for the plating, particles for toys, bushings.
