10% polyimide filled PTFE rod is made from PTFE using a modification of 10% Polyimide. 10% polyimide filled PTFE rod has low wear rates and low coefficient of friction and it is used in seal components for static and dynamic applications where resistance to high pressure and temperature is key.
10% polyimide filled PTFE rod exhibits low friction and minimal wear in rotary and reciprocating sealing applications. It performs well against soft mating surfaces such as aluminum, mild steel, brass, and plastics, and it is ideal for use in stop-start applications where the goal is to eliminate stick-slip. This material is suggested for use in applications with service temperatures ranging from -240 °C to 287 °C.
Ideal applications for polyimide-filled PTFE
10% polyimide filled PTFE rod is used for self-lubricating bearings, compressor rings, piston ring seals, Big-billet. It is also good for high Temperature and high pressure. 10% polyimide filled PTFE rod has extremely low friction and are non-abrasive, making them ideal for applications involving softer mating surfaces such as steel, aluminum or other plastics. Therefore, polyimide-filled PTFE rod is particularly suitable for dry operation and start-stop applications. However, polyimide is an expensive PTFE filler, so you need to consider the cost when choosing it.
Advantages
10% polyimide filled PTFE rod has the characteristics of high wear resistance, high and low temperature resistance, self-lubricating, low noise, stable size, and not easy to damage to abrasive objects.
