NuSil MED-4025 Silicone, Two Part High Consistency Elastomer - Restricted 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: 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: Low Tension Set Cure System: Platinum Information provided by NuSil
