Filled PTFE Rods

Product Code: Dolgulu PTFE Çubuk
Definition : Filled with the molding operation can be made of PTFE resin. Suspension polymerized PTFE resin is mixed with a wide variety of filler. More glass fibers as fillers, carbon fiber, bronze, graphite and molybdenum sulphide is used as a lubricant. As can be seen from the specification table, filled compressive strength and wear resistance of PTFE is higher than that of pure PTFE. The following table is provided in order to provide an idea of the characteristics of pure and filled PTFE material.

In fact, numerous combinations of fillers according to usage purposes. Of these, the most application areas are filled with glass fiber and carbon fiber filled alloy. Reinforcement material, prominence should be selected according to the importance of the desired feature.
