CHT Group QM 140 QSI Quantum Silicones 40 Durometer Condensation Cured Moldmaking Material
Categories: Polymer; Thermoset; Silicone

Material Notes: QM 140 is a two-component, room temperature condensation cure silicone material. The cured rubber has excellent mechanical properties and good shelf-life stability. This material is an excellent choice for the molding of intricate patterns, skin molding and applications where high durometer, dimensional stability and extremely tough rubber are required. Complies with FDA indirect food contact regulation CFR 177.2600 when used with Cat Clear FG. Refer to Cat Clear FG data sheet for specific properties.

Key Features:

  • Low viscosity
  • High tear strength
  • Fast demold time
  • Excellent dimensional stability
Main Applications:
  • Molds for polyester, polyurethane and epoxy resin castings
  • Molds for technical articles and prototype
  • Molds for furniture and picture frame replication

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