Oil-resistant asbestos rubber sheet is a blend of compressed long asbestos fiber, oil-resistant synthetic rubber, heat-resistant filler. It is mainly for C1 ~ C5 hydrocarbons (gas and liquid), coke oven gas. Oil-resistant asbestos rubber sheet is manufactured in the form of sheets. Paronite sheet can be cut into pads for its good machinability.
