By certification 
CR rubber sheet is a kind of rubber sheet, which has good physical and mechanical properties, oil resistance, heat resistance, fire resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. Therefore, the use of CR rubber sheet is very wide, it can be used as both general rubber and special rubber. CR rubber sheet also has disadvantages, its cold resistance and storage stability is poor. Used as acid and alkali resistant lining, liner and rubber ring. CR rubber sheet is used for punching all kinds of oil resistant oil seals, seals and rings, worktables and floors in contact with grease, laying of electronic products and thermal aging places, with good sealing and anti expansion properties.
CR 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
