Cork Rolls & Sheets

Cork Sheet Cork Rolls

Our standard grade of cork is Nitrile Bonded (ref 2001) which is a highly compressible material suitable for low and medium bolt pressure, with good flexibility and resilience. These characteristics along with fuel and oil resistance make this a general purpose gasket material

Applications: general applications for cork sheeting include gaskets, washers, anti vibration, crocodile strips, pipe insulation, glass polish wheels, roller covering
