Product Introduction
PTFE modified polyphenylene sulfide (PPS)
The disadvantage of PPS is that the impact resistance is poor, and processing and molding are difficult. Since the inert surface of PTFE is difficult to bond with PPS, a solubilizing agent is used to reduce the tension at the interface between the two phases, and the technology of mixing at a high rate is used to alloy the incompatible system.
PPS powder is mixed with the mixture, and PTFE powder is added to make the coating.
The coating has excellent friction and wear resistance. It can still maintain high mechanical properties above 300 degrees. It is mainly used for corrosion-resistant pumps and valves. And dynamic seals, shaft sleeves, automotive engine bonnets, chromatography seals and more.
Product Parameter (Specification)
Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.
PTFE seals have three basic design elements
A pressure-actuated U-shaped jacket
A metal spring loading device
High performance polymeric seal materials
Product Details
High Performance
The unique design and material properties of these seals provide design engineers with a new assortment of solutions to difficult applications.
Some of the more remarkable capabilities of the seal include
Very low friction
Universal chemical compatibility
High speed service
Cryogenic service to -425 degrees Fahrenheit
High temperature service to 575 degrees Fahrenheit
High pressure ratings (over 30 Kpsi)
Permanent elasticity with immunity to aging embrittlement and compression set.
Many of these capabilities are the result of the materials used to make the seal. Seal jackets, made from low-friction PTFE and various blends, are chemically inert, extrusion resistant and capable of operating over a wide temperature range. The lack of resilience of the polymer is overcome by a spring load made from one of several corrosion resistant metals.
The spring energized seal's combination of material and design configuration eliminates many of the problems associated with O-rings or other elastomeric seals. For example, when selecting an elastomeric seal to handle a variety of solvents, it is necessary to review the compatibility of the elastomer in each of the solvents. In many cases, none of the commonly used elastomers are satisfactory for the intended range of fluids.
