Introduction
UHMWPE English name ultra-high molecular
weight polyethylene (UHMWPE), more than one million molecular
weight polyethylene.

UHMW-PE plate
features:1. High impact
resistance 2. High wear resistance 3. Anti-corrosion 4. Non-fouling
5. weathering and aging resistance 6. The optimum temperature of
the wide 7. flame retardant 8. Light weight, easy
installation.
Performance:
Ultra-high molecular weight polyethylene
(UHMW-PE) for its viscosity-average molecular weight of 1.5 million
****0 million (ordinary polyethylene **3 million) given its
superior performance:
1.
Abrasive resistance
The
wear resistance of UHMW-PE rank first in the plastic crown,and more
than a certain metal, The wear resistance of UHMW-PE is in
proportion to its the molecular weight, the higher the
molecular weight, the better the abrasive
resistance.
2.
Impact resistance
The
impact strength of UHMW-PE,in the highest fame of all engineering
plastics,The impact strength of UHMW - PE is 2 times of PC, 5 times
of ABS, *0 times more of the POM and PBTP. Impact strength increase
with increasing molecular weight,The molecular weight was ******0
and reached a maximum value, and then continues to rise with
the molecular weight gradually decreases .
3.
The self-lubricating
UHMW-PE has a low coefficient of friction
(0.***0.*1), it is an excellent self-lubricating properties. Second
only to the best self-lubricating of plastic
polytetrafluoroethylene (PTFE) in the absence of lubrication; when
it is working to form a sliding or rotating, its lubricity than
steel and brass add lubricating oil even better .
4.
chemical resistance
UHMW-PE has excellent chemical resistance,In
addition to strong acid liquid fluoride, but at a certain
temperature and concentration ability of corrosive media (acids,
bases, salts) and organic media (except tea solvent). Immersed in
*0 and *0 of *0 kinds of organic solvents for *0 days, without the
appearance of any anomaly, other physical properties are almost not
change.
5.
The impact energy absorption
UHMW-PE having excellent impact energy
absorption, the impact energy absorption maximum in all plastics.
Thus noise damping is very good, with excellent sound deadening
effect.
6.
Health non-toxic
UHMW-PE with health and non-toxic, fully
compliant with the Japanese Health Association, and the US Food and
Drug Administration and the US Department of Agriculture approved,
can be used in contact with food and drugs.
7.
nonstick
UHMW-PE surface adsorption force is very weak,
and its anti-adhesion ability is only second to plastic viscosity
best PTEE, thus the product surface adhesion with other materials
is not easy.
8.
hydrophobic
UHMW-PE, low water absorption, typically less
than 0.*1%, only 1% PA6, thereby forming generally do before
drying
