 PTFE rod, tube, plate, mechanical turning, cutting, or suspended by the PTFE resin molding method forming at room temperature, then made by sintering, cooling pads, cross-section for the flat-shaped, V-shaped. Pure PTFE gasket seal products is a clean, not any of the substances in contact with its formation of pollution, can be widely used in food, pharmaceutical and other industries. 

 Features: with excellent corrosion resistance, good self-lubricating and non-adhesive, resistant to almost all chemicals, wear, pressure, and low coefficient of friction characteristics. 
 Applicable in many fields: petroleum, chemical, metallurgy, machinery, transportation, medicine, food, electricity and other. 
 The main technical parameters of the pure PTFE gasket: 
 Pressure (Pressure): 10Mpa 
 Temperature (Temperature): 280 ° C 
 Ph value (pH range) :0-14 
 Note: when the temperature is below -185 ℃. PTFE gaskets become brittle. 

 PTFE envelope gaskets 


 PTFE envelope gaskets is a non-metallic gaskets, general coating and insert composed of two parts. Coating mainly from corrosion, usually made of PTFE, embedded material (filler) for the good elasticity with or without metal reinforcement layer of non-metallic sealing materials, usually asbestos rubber sheet. The gasket according to the structure of the inner core, the sub-V-shaped, U-shaped and L-type. Some containers in the petroleum, chemical, pharmaceutical and food industry, pipe, valves, connections, in order to ensure the material clean often using PTFE gasket seal. It is widely used in a variety of acids, alkalis, strong oxidizing, chlorine, and do not allow contaminated medium sealed. 

 Metal Jacketed gasket types: 
 S-type, split type, the PTFE piece cut from the outer to the inner wall of the applicable low-pressure economy. 
 M-type machining (square), formed by the PTFE sheet mechanical turning, suitable for medium and high pressure. 
 F-type, folding package type, PTFE tape wrapping heating bonding from, generally used for more than 200mm in diameter

 Asbestos gasket 

 Asbestos rubber gasket to asbestos rubber sheet, red cut is made. Applies in the low pressure valve head and the pipe flange seal. Gasket good stability, good sealing performance. Depending on the formula, process performance and use of asbestos rubber pads can be divided into ordinary asbestos rubber gasket and oil resistance asbestos rubber gasket. Different depending on the temperature and pressure can be divided into low-pressure asbestos rubber gasket, pressure asbestos rubber pads and high-pressure asbestos rubber gasket. 

 The largest processing size: ~ 1500mm; special specifications or various non-standard products according to customer requirements to develop. 
 Main technical parameters: 
 Model: XB200, XB300, XB350, XB400, XB450, NY250, NY300, NY400 ...
