Langfang Bokai Sealing Material Factory is a privately-owned enterprise specializing in the production and processing of sealing materials and other products. The company is headquartered in Dacheng County, Langfang City, Hebei Province. The company's main products are asbestos mats, ceramic fiber packing, PTFE products, graphite sealing fillers, metal winding mats and other products. Below we briefly introduce what are the common sealing gaskets? Sealing gaskets are materials used for sealing inside machinery, equipment, pipes, etc. Common gaskets are as follows:

High and medium pressure asbestos rubber sheet gasket: Asbestos rubber gasket is made of asbestos fiber and rubber as the main raw material, supplemented by rubber compounding agent and filler, and is prepared by mixing, hot roll forming and vulcanization.

Oil-resistant asbestos rubber gasket: It is made of high-quality asbestos fiber, oil-resistant fiber, filler, coloring agent, etc. It is widely used in pipelines and equipment of petroleum and chemical industry. It can choose the corresponding grade according to working conditions. Oil-resistant asbestos gaskets are mainly used for the sealing of steam, hydraulic, gas, oil solvents and non-corrosive media.

Seal: A sealing product made of a high-strength, high-abrasive aramid fiber as a main material and a special lubricious material. This sealing product has excellent lubricity and wear resistance. On liquid devices mixed in solid-liquid phase, its outstanding characteristics can be displayed.

Non-asbestos board gasket: It is a sealing material made of organic fiber such as aramid fiber and plant fiber, nitrile rubber and inorganic minerals at high temperature. Due to the small amount of asbestos fiber, it is suitable for asbestos gasket without asbestos gasket. A replacement for the film. Non-asbestos gasket (non-asbestos gasket) has high strength and good resilience, and has excellent anti-penetration performance. It is a good environmentally friendly material for replacing asbestos gaskets under high temperature and high pressure.

Asbestos pad: Molded with asbestos cloth and other auxiliary materials, used for corrosive high pressure and high temperature sealing. Used in reactors, reaction tanks, manholes, hand holes, etc. Operating temperature: -100 ° C - + 1000 ° C; use pressure: PN
Rubber mat: a kind of vinylidene fluoride and non-fluorine, propylene fluoride, propylene copolymer gel elastomer, widely used in the defense industry and civil industry, characterized by: high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, resistance Fuel oil, lubricant resistance, strong oxidant resistance, chemical resistance and electrical insulation properties.

Teflon-lined rubber mat: Polytetrafluoroethylene-lined rubber gasket is a tetrafluoroethylene-encapsulated rubber composite gasket. It has strong anti-corrosion performance and high sealing resilience. It is suitable for anti-corrosion sealing of low-pressure chemical equipment such as enamel and glass pipes.
