Non-Asbestos Jointing Sheets are made of special non-asbestos heat-resisting fiber, heat-resisting packing material, and special nature or NBR rubber compound heating and compression molding it.
1) Non-asbestos rubber sheet series include: NXB200, NXB300, NXB350
Uses: Substitution of corresponding models of asbestos rubber sheet ,Used for the equipment in water,steam,etc.and used as sealing material in the joints of pipeline
Working pressure : 1.5～8.0 MPa ,Working temperature : 200 ～350℃
2) Oil-resistance non-asbestos rubber sheet series include: NNY150, NNY250, NNY300, NNY350
Uses: Substitution of corresponding models of asbestos rubber sheet , Mainly used as the aviation liquid the motive’s kerosene, lubricant, the fuel oil and cold air system to join together the seal completely of place the sealing gasket material.

Sheeting rubber products are most often sold in the form of rolls. Our sheet rubber rolls are usually stocked in gauges between 1/32” to 2” in thickness, depending on the specific type of elastomer. Since our sheet rubber is sold in roll form, they can be acquired in custom lengths of up to 25 or 50 ft according to your specifications. This will help ensure that you have the exact amount of material you need for your project. More importantly, however, you should know which type of material to choose from.
