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. Series 300-700: COHRlastic general-purpose molded sheet is available in thicknesses up to 1/2" and it withstands temperatures from -100°F to +500°F. RED in color.All data based on a 0.25 inch test sample.(Also comes in thicknesses from 1/16" to 1/2") Information provided by Saint Gobain Performance Products.
