Covering Ring PTFE Covering Ring Professional Manufacturer
Detailed Description of Covering Ring
Composition
PTFE Covering Ring combines the elasticity and sealing properties of rubber with PTFE The chemical resistance of ethylene is organically combined. It is composed of an inner core made of silicone or fluoroelastomer and a relatively thin outer covering of (polyfluoroethylene-propylene) or (soluble polytetrafluoroethylene). Rubber sealing ring has excellent sealing performance.
Function
The combination of the seamless and dense and uniform surface of the PTFE outer coating and the rubber inner core ensures that the entire PTFE coating ring maintains consistent sealing performance and the elasticity of each point on the sealing ring. Evenly compressed, it can be installed and used repeatedly under continuous pressure. As the medium pressure increases, the entire sealing ring is compressed.
Compressibility
The existence of the PTFE outer coating makes the PTFE coating ring have good resistance to hardening and brittleness, while the inner core made of silicone rubber or fluorine rubber makes the sealing ring It can still maintain good elasticity under high temperatures of ℃. The PTFE coating ring has good compression resistance while maintaining rubber properties. The manufacturing of PTFE coated rings requires strict quality control. A special process is used to completely cover the rubber core with PTFE polymer, and to ensure that the ring has the required standard tolerances. . Compared with any other rubber or pure polytetrafluoroethylene ring, the PTFE coated ring has unparalleled sealing performance and long life, especially when used in harsh media.

Installation instructions for the PTFE coating ring
The parts where the PTFE coating ring is installed or passed must be smooth , no burrs, grooves and sharp corners, the inner bore shall have a milli-inch profile and the shaft shall have a milli-inch profile.
Use clean light oil or grease to lubricate the surface of the PTFE coating ring and the related parts in contact with it.
If it is difficult to install the PTFE coated ring on the shaft, you can immerse it in hot water for a few minutes to expand it. This softened and expanded ring is easier to install. Install the ring while it is hot, and it will return to its original size when it cools down.
Do not bend the PTFE coating ring too sharply, otherwise it will cause wrinkles in the PTFE and affect its use.
The required compression amount of the PTFE coating ring is as follows
Static sealing state
Dynamic sealing state
Pneumatic state
Chemical corrosion resistance
Outer coating It is a basic component of the PTFE coating ring. It has excellent resistance to chemical corrosion. Under normal operating temperatures, it is only corroded by a few chemicals. Only chemicals that are not compatible with it are listed here. , such as some metal bases, fluorine and some halides.
