Reinforced PTFE
Teflon have excellent friction resistance, both static and dynamic, that can be improved with certain fillers and reinforcing agents, such as brass, fiberglass, carbon and graphite.
Reinforced PTFE
PTFE +15% / 25% Fiberglass
It has the best balance of mechanical, electrical, and chemical properties. It resists acids and alkalis, except hydrofluoric acid and strong alkalis. It exhibits good friction wear on hard surfaces. It wears more easily when lubricated with water. It is the most suitable for electrical applications.
PTFE +15% Fiberglass +5% Mos2
Good balance of mechanical, electrical, and chemical properties. Resists acids and alkalis, except hydrofluoric acid and strong alkalis. It wears more easily when lubricated with water. It has similar applications to PTFE with fiberglass, but incorporates molybdenum disulfide and is comparatively less abrasive, has a lower coefficient of friction, and similar wear and electrical properties.
PTFE+15% Graphite
Good chemical properties. It works poorly in dry conditions and well with moisture or water. It has the lowest coefficient of friction of any filled PTFE. Not suitable for vacuum applications due to lack of moisture. It withstands scuffing wear well under light loads and high surface speeds. It is best suited for friction on soft metals (common steels or unhardened stainless steels)
PTFE+40%/60% Bronze
Good mechanical properties. Good thermal conductor. Great resistance to deformation under load. Resists gall wear under very heavy loads and low speeds. It is best suited for hydraulic systems. Not suitable for chlorine, acids, or pure oxygen.
PTFE+25%/33% Carbon
Good mechanical and chemical properties. Not recommended for oxidizing environments. Antistatic. Works well both dry and wet. Good heat conductor. Withstands scuffing wear well under heavy loads at intermediate surface speeds. Suitable for compression rings. The 33% compound is the only one that can be bonded without chemical treatment. Not recommended for oxidizing environments. Works well both in dry and wet environments and is a good heat conductor.
