NuSil MED-4750 Two-Part Standard High Consistency Elastomers - Unrestricted Medical Use
Categories: Polymer; Thermoset; Silicone; Silicone Rubber

Material Notes: Description: High consistency rubber, or HCR, consists of high molecular weight polymer combined with silica to produce a material that can be molded, extruded, or calendared into a useful end product. An HCR has the consistency of clay and is primarily formulated in a one or two part system (peroxide and platinum catalysts, respectively).

Important Properties of Adhesives: Most platinum cure high consistency rubbers are two component systems with an easy-to-work-with 1:1 mix ratio. Features of platinum cure high consistency rubbers include the following:

  • Two part (typically)
  • Heat accelerated
  • No byproducts
  • Post cure optional
  • Low percent shrinkage
Comments: High Tear

Cure System: Platinum
