CHT Group QM 132T 30 Shore A, Translucent, Condensation Cure Moldmaking Material
Categories: Polymer; Thermoset; Silicone

Material Notes: Product Description: QM 132T is a two-component, translucent, room temperature, condensation cure silicone material. When catalyzed with QM Cat Clear Thixo 2, the resulting material is extremely thixotropic. QM 132T is also available for non-thixotropic, flowable applications when catalyzed with QM Cat Purple or QM Cat Purple SR 2. The cured rubber has excellent properties and good shelf life stability.

Key Features:

  • High tear strength
  • Fast demold time
  • Excellent dimensional stability
  • Excellent styrene resistance, when used with QM Cat Purple SR 2
Main Applications:
  • Molds for polyester, polyurethane and epoxy resin castings

Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
