PI Filled PTFE Tube
Style
9001 polyimide filled PTFE teflon 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 stainlesss 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 Compounds 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.

Application of Polyimide Filled PTFE Teflon Tube
The polyimide filled PTFE teflon 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 contac us.

The Way to Solve the Problems of PTFE - Lack of Wear Resistant Ability, and Creep.
Method 1:Ekonol Filled PTFE
Polyphenylester
usually called POB or Ekonol, which has high mechanical rigidity in a
wide temperature range. It has high compression creep resistance, easy
machining, high load-bearing capacity and good self-lubricity. POB has
high thermal stability, thermal conductivity in plastics, good
electrical insulation and excellent chemical resistance. Ekonol can be
blended with PTFE in any ratio such as 10%, 15%. Ekonel filled PTFE
retains a series of characteristics of ptfe and pob Ekonol such as heat
resistance, lubrication, insulation, solvent resistance, etc. The
characteristics can be complemented in performance, which overcomes the
lack of wear resistance and poor thermal conductivity of PTFE and the
brittleness of polyphenylester.
Method 2: Polyimide Filled PTFE
Polyimide
plastic is the most resistant to high temperature and most
wear-resistant plastic in the current plastics, the product size is more
stable, and the creep resistance is good. It can be blended and molded
with PTFE in the corresponding ratio, the product has a longer service
life, and has good self-lubricating performance. It is mainly used for
air seals.
The difference between Ekonel (POB) and Polyimide
POB Ekonol
is much cheaper than polyimide. The process of blending POB and PTFE is
simple, and the process requirements of blending polyimide and PTFE are
more sophisticated. For products with low requirements, POB and PTFE
modified products can be used, but for air seals, only polyimide and
PTFE modified products can be used. Polyimide plastic and PTFE products
surpass POB and PTFE products in terms of performance. Hot Tags: Polyimide Filled PTFE Teflon Tube, China, Manufacturers, Suppliers, Factory, Wholesale
