1. Excellent wear resistance.
UHMWPE wear resistance ranks first all plastic material, 66 times than nylon, 4 times than
polytetrafluoroethylene, 9 times than ordinary polyethylene, even more than ordinary metals,
is 7 times than that of carbon steel, and 10 times than stainless steel, greatly improved the
service life.
2. Light weight. The density UHMWPE is about 0.94g / cm3, lower than other engineering
plastics, 1/2 lighter than polytetrafluoroethylene, 1/7 light of the steel pipe, thus easy for
installation, reducing the energy consumption.
3. Self-lubricating. The friction of UHMWPE is very low and good self-lubricating performance,
better than other metal pipelines.
4, Chemical resistance. UHMWPE has the high chemical stability and anti-corrosive ability in
the certain range of temperature and concentration ability of various of corrosive media
(acids, bases, salts) and organic media.
5. Lower water absorption. UHMWPE is almost non-absorbent, does not swell in water, much
less absorbent than nylon.
6. Non-stick performance. The UHMWPE surface is very weak, almost equal to PTFE, thus
no scale deposit at the pipe surface.
7. Excellent impact resistance. UHMWPE has the superb impact resistance, 2 times better
than polycarbonate. Even in the ammonia temperature (-269 ℃), it can still maintain good
impact resistance, which make it a wide application in cryogenic engineering field.
8. Good sanitation. UHMWPE meet the national health standard, even up to the standard
of human-contact field.
In addition, UHMWPE also has excellent ability of cracking-resistance, electrical insulation-
resistance, fatigue-resistance, deformation-resistance under high temperature,
γ-rays-resistance and other superb characteristics.
