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.
Because European and American countries have detected that asbestos materials are inhaled and cannot be discharged out of the human body, they are considered toxic substances, so asbestos is gradually eliminated. As non-asbestos materials are too expensive, non-asbestos materials can replace non-asbestos at low prices. The official non-asbestos content is 10%, but the content of non-asbestos testing is <5%, which is mainly for the requirements of Europe, America, South Korea, and Japan except Not high country. The non-asbestos rubber sheet is made of special heat-resistant fiber (sepiolite), natural rubber, and oil-resistant rubber as raw materials, and is pressed to replace the asbestos rubber sheet with the same label. It is used as a sealing gasket material for pipe flange joints.
1) Non-asbestos rubber sheet series include: NXB200, NXB300, NXB350
Uses: 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: FNY150, FNY250, FNY300, FNY350
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.

At the same time, steel wire net inserted (coated graphite) is available.
Packing: in wooden pallet of about 1000 kgs, 2000kgs net each.
A non-asbestos sheet is also called non-asbestos sheet. It is a sealing sheet made of non-metallic materials as fillers, natural rubber, nitrile rubber, etc. as binders, organic and inorganic fibers as the frame, and rolled. 100% asbestos-free. It is a substitute for imported asbestos-free products. The non-asbestos rubber sheet is safe and environmentally friendly and is used to process various sealing gaskets. The non-asbestos rubber sheet is 100% asbestos-free, the product is safe and environmentally friendly, and can be used in places where asbestos rubber sheet is not allowed. The quality of asbestos fiber has a great influence on the performance of asbestos rubber sheet, so the asbestos fiber is required to have high tensile strength, good heat resistance, a certain length, and the fiber is easy to bend and be elastic. Generally, high-pressure asbestos rubber sheets and oil-resistant asbestos sheets above No. 400 use asbestos fibers of grade 2 and 3. Due to restrictions on the use of asbestos rubber sheets, Fuyuan non-asbestos rubber sheets are used to replace the original asbestos sheets.
