Robert McKeown Co., Inc. - Silicone Solid Rubber Tape

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 generalpurpose molded sheet is available in thicknesses up to 1/2" and it withstands temperatures from –100 °F to +500 °F.

Series 9030 - 9070 COHRlastic is also general-purpose, but is produced in 36" wide continuous lengths for the most efficient utilization of material, minimizing waste. Standard thicknesses are 1/32", 1/16" and 1/8".Withstands temperatures from –100 °F to +500 °F. Please consult plant for availability of additional thicknesses and colors.

Series 9200 high-performance COHRlastic provides excellent tensile strength and superior tear resistance. It is tougher and more resilient than generalpurpose 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 .015" is available on a minimum quantity basis. Red color is standard for general-purpose goods. Black or gray can be provided on a minimum quantity basis.The 9200 series is standard in gray, but clear or red can be supplied on a minimum quantity basis. Contact plant for minimums.
