Oil-resistant rubber sheets are industrial products made primarily from rubber (which may include reinforcing materials such as fabric or metal sheets), formed through the vulcanization process, commonly referred to as rubber sheets. They are categorized by structure into solid rubber sheets, cloth-reinforced or metal-ribbed sheets, and by application into industrial rubber sheets and rubber flooring. Colors include black, red, white, green, and more. Production is carried out using calendering and lamination or extrusion molding techniques, and are processed into finished products through flat or drum vulcanization machines.
