By certification 
NBR rubber sheet is made from butadiene and acrylonitrile by emulsion polymerization, and NBR is mainly produced by low temperature emulsion polymerization. NBR rubber sheet works in oil (engine oil, diesel oil, gasoline, lubricating oil) medium, and has sealing and anti expansion properties. It is used for punching all kinds of oil resistant oil seals, seals and rings, as well as the laying of worktable, ground and electronic product places in contact with grease;
NBR rubber sheet can be made pure rubber sheet or cloth inersion pattern. The surface can be made smooth pattern or cloth pattern.
Size generally: Width 0.1m-2m, thickness 1mm-100mm, length according to your request
