Physical character: made by drum-type vulcanizing press(ROTOCURE) or vulcanizing press with high quality natural rubber(NR). The natural rubber is from the natural rubber tree with middling hardness and high tensile strength, high elongation, good abrasion resistance, elasticity, safety and nontoxicity without smell. The pure natural rubber sheet is also named gum rubber sheet or para rubber sheet. 1-6mm thickness is made by drum-type vulcanizing press(ROTOCURE) with shiny surface, 7-80mm thickness is made by vulcanizing press for get higher thick thickness. Working under the higher pressure, wearing resistant, food grade lining status at the temperature of -35°C – +85°C in air or water. Apply to punch all kinds of seals, gaskets and others applications with its good function, for example of truck lining, drinking water lining or rubber membrane special for PVC vacuum laminating press.
