Product Description

Factory Offer 40% Bronze Filled PTFE Molded Tube Good Quality


Modified Polytetrafluoroethylene (RPTFE)
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.

Advantages:
♦High temperature resistance 
The working temperature is 250ºC
♦Low temperature resistance
Good mechanical toughness; even if the temperature drops to -196ºC,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. 


PTFE filled with other materials:

Filled materials	Common filled ratio (Quantity %)	Main performance
