Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitirle. It is the most commonly used elastomer for sealing products. It has a temperature range of -40F to +250 F and is exceptionally resistant to petroleum base oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties
Silicone rubber cord is an ideal sealing material due to its consistent compressibility across a broad range of temperatures (-40°C up to +200°C). Commonly used in precision sealing applications where exact size o-rings are unavailable, this material offers fantastic flexibility, excellent electrical insulation and can also be bonded through the use of specific adhesives (sold separately). Supplied in coils, cut lengths or as vulcanised o rings, silicone cord is available various diameters. As standard, we supply this cord in white, blue, translucent and red oxide, but other colours are available upon request. For hygiene critical applications, we also offer this product in blue, metal detectable grade.
