Saint-Gobain COHRlastic® 9235 High Performance Silicone Solid Rubber
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone

Material Notes: Description: COHRlastic® solid silicone rubber in square sheet and continuous length form has a smooth, blemish-free surface. It is available in degrees of hardness from relatively soft 30 durometer to the relatively hard 70 durometer on the Shore A scale. It is manufactured in different formulations to provide a choice of physical properties and cost considerations. 9200 Series: COHRlastic 9200 High Performance Series provides excellent tensile strength and superior tear resistance. It is tougher and more resilient than general-purpose silicone. Standard thicknesses are 1/32", 1/16" and 1/8", and it withstands temperatures ranging from -100°F to +400°F. A minimum thickness of 0.015" is available on a minimum quantity basis. All data based on a 0.0625 inch test sample.(Also comes in thicknesses from 1/32" to 1/8")
