What is Polyimide Filled PTFE Tube?
Polyimide filled PTFE tube is made from PTFE using a modification of 10%, 15% or 20% Polyimide. Its own properties contain diminished creep under load and excellent sliding as well as friction attributes. The material is ideally fitted to applications involving gentle mating products.Polyimide means a class of manufactured polymers, also referred to as PI briefly. Putting polyimide makes a PTFE compound that is definitely lessen in friction than those previously described. It is actually non-abrasive, which makes it your best option for applications including much softer mating surface types like stainless steel, aluminium, or other plastic materials. Polyimide filled PTFE tube therefore matches dried up functioning and stop-start applications particularly effectively. Nonetheless, polyimide powder matertial is the costly of the PTFE fillers.
Being the amongst China main maker and distributor of filled PTFE compounds, polyimide filled PTFE compound we are able to create in tube, rod, sheet styles. As well as compared with normal PTFE compounds, the working temp can be as much as 312°C.
Polyimide in PTFE Tube Improves the Properties.
The most important character of Polyimide filled PTFE tube is excellent wear resistance at elevated temperature, higher elongation, and also no abrasion of the sliding partner - all without making use of lubrication. So it is a really good self-Lubricating material.Polyimide as an active filler in PTFE increases the mechanical character of the PTFE. Blending 5% to 20% polyimide powder with PTFE makes the PTFE compound has better wear resistant that increase the performance especially at higher stresses, velocities and temps. Polyimide filled PTFE compounds are especially great running against very soft mating surface areas.
Teflon® is a authorized brand of E.I. duPont de Nemours and Company
Application of Polyimide Filled PTFE Tube
The polyimide filled PTFE tube can be machined be all kinds of parts and seal used for many applications, such as piston rings in pumps, lip seals, bearings, compressors for dry gases, spring-reinforced dynamic seals, rider and piston rings in compressor. Other applications usage please contact us.
