SGS is a halogen-free silicone coated heat treated glass braided sleeve with a continuous operating temperature from -70°C to +235°C. It withstands short-term peaks up to 300°C, is a class 200 insulating sleeve and available in several voltage grades. It is supplied in sizes up to 20mm as standard.

This extremely flexible, silicone rubber coated fibreglass braided jacket is self-extinguishing to VW-1 and offers excellent resistance to oils, fluids and many chemicals. Its thermal and electrical insulating properties make it ideal for applications operating at high temperature with thermal overcharges such as incandescent lamps and domestic appliances. It is also frequently used in wire harnesses, transformer leads, power supplies, motor coil and heater leads. We also supply knitted silicone coated sleeving on enquiry.
