PTFE sheet

PTFE sheet is one of the most thermally stable plastic materials displaying no appreciable decompositions at 260°C and retaining most of its properties
Its high melting temperature makes it a good choice as a high-performance substitute for the weaker and lower melting point polyethylene that is commonly used in low-cost applications

Components made with PTFE sheets have an exceptional resistance to high as well as low temperatures, chemical reaction, corrosion, and stress-cracking. The electrical and low-friction properties of PTFE make it a preferred material for a number of applications and for different processing techniques.

Owing to its low friction, PTFE sheet is used for applications where sliding action of parts is needed such as plain bearings, slide plates, etc. PTFE sheets have high corrosion resistance and used in laboratory environments as containers for materials such as fluoroantimonic acid.

PTFE sheet offers super low friction, high chemical resistance, low and high temperature capability, resistance to weathering, electrical and thermal insulation, and unrivalled “slipperiness”

PTFE is the most chemically resistant plastic yet known. Very few chemicals will react with it. Its mechanical strength properties are low compared to other engineering plastics such as nylon, but its properties do remain over a great temperature range. Its working temperatures are exceptional at -240 to +260°C. PTFE has outstanding thermal and electrical insulation properties. And, it is famous for its very low coefficient of friction.

PTFE Sheet is often used as an electrical insulation material because of its high dielectric strength, high temperature resistance and ease of handling. It remains stable at both cryogenic and elevated temperatures.

Applications

PTFE sheet due to its excellent sliding properties, high thermal stability and chemical resistance is suitable for use in a wide range of industries including transport and conveying, pump and instrument construction, electrical engineering, food processing and medical, aircraft and aerospace, laser technology and many others. Due to its unique properties PTFE plastic can be used in the fabrication of components for sliding applications that are subject to a high level of chemical stress. Components that can be manufactured from this plastic include the following:

• Slide bearings and runners
  • Pump housings and parts
  • Valve seats
  • Tank linings
  • Roller coverings
  • Pipe linings
  • Filter housings
  • Etching plates
  • High frequency insulation
  • Seals
