Product Introduction
There are two styles of PTFE sheets, PTFE molded sheets, PTFE skived sheet. PTFE molded sheet is manufactured by molding method with PTFE granular resin. PTFE skived sheet is formed by pressing the PTFE suspension blank into shape by skiving.PTFE is the most chemical resistance of all known plastics. It does not age. It has the lowest coefficient of friction of all known solid materials and a wide range of practicable temperature from -180degree +260 degree.

PTFE sheet Advantages
PTFE sheet is great material for high-temperature and low-friction applications. It has a number of advantages that make it a good choice:
Its coefficient of friction is the third-lowest of any known solid material.
PTFE sheet has excellent dielectric properties and is suitable for use as a material for printed circuit boards used at microwave frequencies.
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.
PTFE sheet Perform
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.
PTFE is generally safe to use around the majority of known substances and elements. Only elementary alkaline metals, chlorine trifluoride, and elementary fluorine can attack it at high temperatures and pressures. At temperatures over and close to 300 °C, PTFE doesn't dissolve in the majority of solvents. Fluorinated hydrocarbons have the ability to produce some temporary expansion. This excellent engineering plastic can be dissolved by some oils that are heavily fluorinated and at temperatures above 300 °C.
PTFE sheet application
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. In these applications, it performs significantly better than nylon and acetal and it is comparable to UHMWPE, although not as resistant to wear. It’s extremely high bulk resistivity makes it an ideal material for fabricating long-life electrets, which are useful devices being the electrostatic analogues of magnets. In optical radiometry, PTFE sheets are used for measuring heads in spectroradiometers and broadband radiometers (e.g., luminance meters and UV radiometers) due to its capability to diffuse a transmitting light nearly perfectly. PTFE sheets have high corrosion resistance and used in laboratory environments as containers for materials such as fluoroantimonic acid.
