Linde Polymer Tec Co.,Ltd. is one of the most experienced manufacturers and suppliers of ptfe cladding o-rings in China, also supports customized service. Please feel free to buy high quality ptfe cladding o-rings for sale here from our factory.
Products Description
PTFE cladding O-rings is a seal made of a relatively thick inner core made of silicone rubber or fluoro rubber and a relatively thin outer PTFE coating. This product combines the elasticity and sealing properties of O-ring rubber materials with the chemical resistance of polytetrafluoroethylene materials and has excellent sealing performance.
Our company can open molds and process custom fluorine-clad O-rings of various colors and shapes according to the drawings, samples, specifications, and materials provided by customers.
Main Features
It has excellent chemical resistance and can be applied to almost all chemical media, such as strong oxidizing and reducing solvents, and is highly corrosive to strong acids and alkalis; it has a very wide applicable temperature range, from -200℃ to 260℃; it has very good compression resistance, greater than or equal to 30%; it has a very small anti-friction coefficient, only between 0.1 and 0.2; it has good anti-swelling resistance ≤0.1%; it is extremely resistant to high pressure, up to 60Mpa; it has good sealing continuity, and can increase the service life by more than 5 times.
Hardness Description
The average hardness of coated O-rings of different materials is as follows:
Hollow silicone rubber: 75-80
Solid silicone rubber: 85-90
Solid fluoro rubber: 90-95
Application Fields
PTFE cladding O-rings are currently mainly used in pumps, valves, reaction vessels, mechanical seals, filters, pressure vessels, radiators, boilers, pipeline flanges, gas compressors, and other related equipment.
