Description

 

PTFE has excellent performance, but it also has some shortcomings, such as poor creep resistance, easy wear, low mechanical strength and so on. RPTFE composite can be prepared by filling some reinforcing agents in PTFE (or PCTFE). These fillers can greatly improve the mechanical strength of PTFE, thus expanding the use of such materials. Fillers include carbon fiber, graphite, tin bronze powder, glass fiber, molybdenum disulfide, polyphenyl ester, para-polyphenyl, polyimide, carbon powder, aramid fiber, calcium sulfate, stainless steel powder, silicon powder, pigments and so on. Different fillers have their own characteristics. They can provide suitable materials according to the requirements of customers' working conditions, and their shapes and sizes can be customized at will.

25% carbon fiber filled PTFE tube has good chemical resistance to corrosive environments, has better creep & wear resistance compared pure PTFE material. These properties are improved with the addition of a carbon fiber filler. This filler improves dimensional stability to raise the heat deflection temperature, improves creep resistance & the dynamic bearing performance. PTFE carbon filled exhibits good initial wear andrubbing or sliding contact characteristics in both dry or water applications. It’s frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive outside particles in their relatively soft surface.

 

Advantages:


♦ High temperature resistance
The working temperature is 250℃
♦ Low temperature resistance
Good mechanical toughness; even if the temperature drops to -196℃,it can also maintain a 5%
elongation.
♦ Corrosion resistance
For most chemicals and solvents, it shows inertia,strong acid and strong alkali, water and various organic solvents.
♦ Climate resistance
The best aging life among all plastic.
♦ High lubrication
The lowest coefficient of friction in solid materials.
♦ Non adhesion
The smallest surface tension in the solid material,which does not adhere to any substance.
♦ No toxicity
It has a physiological inertia and has no adverse reaction in the long term imolantation of artificial blood vessels and organs.
♦ Electrical insulation
It can resist 1500 volts of high voltage electricity.
