Teflon PTFE mixed with 25% carbon (PTFE carbon or PTFE + 25% Carbon) is one of the fluorinated Teflon with 23% carbon and 2% graphite added to Virgin Teflon (PTFE) and has Relatively better features compared to Virgin Teflon (PTFE) and naturally available in black on the market.
Carbon significantly improves the erosion and metamorphic strength of the material and its chemical resistance remains relatively unchanged. However, the electrical properties of the material also increase significantly.
Teflon carbon (PTFE + Carbon) is primarily used in cases where more thermal and electrical conductivity is required than Virgin Teflon PTFE.
It is also modified in durability and compressive strength to Virgin Teflon (PTFE), which makes it suitable for pressurized applications. Teflon carbon (PTFE + Carbon) has good resistance to creep, pressure tolerance, surface coating and abrasion in sliding or scratching applications in dry to lubricated conditions.
Teflon carbon (PTFE + Carbon) is the best type of reinforced Teflon for aquatic environments. It is also very suitable for dynamic applications at high speeds, because thermal conductivity reduces the accumulation of heat on the surface involved and therefore has a better lifespan than other Teflon in these conditions.
