Silicone Rubber, 35-45 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Formulated using only those ingredients determined by the United States Federal Food and Drug Administration (FDA) to be in accordance with Code of Federal Regulations, Title 21 (CFR21), Section 177.2600. ASTM & ISO designation = VMQ. Excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals. Low physical strength and poor abrasion resistance prevents dynamic sealing.

Translucent Silicone Rubber, 45-55 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals, (the low physical strength and poor abrasion resistance prevents dynamic sealing).

White Silicone Rubber, 56-65 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Formulated using only those ingredients determined by the United States Federal Food and Drug Administration (FDA). Water and n-Hexane extraction tested in accordance with Code of Federal Regulations Title 21 (CFR21), Section 177.2600. ASTM & ISO designation = VMQ. Excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals. Low physical strength and poor abrasion resistance prevents dynamic sealing.

Red Silicone 55-65. Diesel cylinder liner ring grade. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. ASTM & ISO designation = VMQ. Excellent heat resistance and low temperature flexibility combined with low compression set performance. Used primarily for diesel cylinder liner O-Rings (coolant sealing). Although silicone will swell in petroleum lubricants, this is not necessarily detrimental in static sealing applications.

Low Compression Set, Red Silicone Rubber, 66-75 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Compounded in accordance with FDA requirements. Low compression set grade, offering excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals, low physical strength and poor abrasion resistance prevents dynamic sealing.

White Silicone Rubber, 68-78 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Formulated using only those ingredients determined by the United States Federal Food and Drug Administration (FDA). Water and n-Hexane extraction tested in accordance with Code of Federal Regulations Title 21 (CFR21), Section 177.2600. Also complies with the requirements of USP 29, NF 24 2006: <87> Biological Reactivity Test ‘in vitro' and USP 26, NF 21, 2003: <88> Biological Reactivity Tests ‘in vivo' Class VI. ASTM & ISO designation = VMQ. Excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals. Low physical strength and poor abrasion resistance prevents dynamic sealing.

Red Silicone Rubber, 66-75 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. ASTM & ISO designation = VMQ. Excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals. Low physical strength and poor abrasion resistance prevents dynamic sealing.

S71U is a high transparency grade of silicone rubber intended for use in food, dairy, brewing, potable water, pharmaceutical and biomedical applications. Platinum-cured silicone is odourless, tasteless and non toxic. Seals made from S71U are resistant to repeated sterilising, autoclaving and cleaning agents commonly used in these industries. Unlike traditional peroxide-cure methods, platinum curing results in a smooth contact surface finish and a high degree of purity. No residue substances such as benzoic acid, peroxides, ketones are produced during manufacturing, which can be transferred from the seal to critical hygienic products. Key Attributes - Compliant with FDA FDA CFR210177.2600 for use with dry, aqueous and fatty food stuffs. - Conforms to USP class VI suffix 87 and 88, Biological Reactivity tests. - Good mechanical and physical properties - Chemically stable over a temperature range of -60°C to +200°C. - Withstands sterilizing and autoclaving procedures - Free from Animal Derived Ingredients (ADI) Typical Applications - Food processing and packaging equipment - Pharmaceutical and biomedical apparatus - Hygienic seals in dairy equipment - Potable and high-purity water applications
