Corrosion Resistance Nylon Gears Made of UHMW-PE Material by
Taking full advantages of UHMW-PE, we produce kinds of special
parts which applied in high corrosion and ≤ 100℃ conditions to
instead of parts made of metal and other materials. The UHMW-PE
parts have very long service life.
Traditional automobile parts are all steel or other metal
materials, it is a ungent need to find a new kind of material to
instead of steel, in order to reduce weight, energy saving,
increase the degree of comfortable and beautiful. Recent years the
rapid development of the plastics industry to meet the requirement
of the automobile industry provides a possible, function of all
kinds of plastic parts and interior parts have been adopted.
Relative to the metal gear, plastic gear light quality, low noise,
wear resistance, no lubrication, can shape more complex shapes, and
low cost of mass production.With the development of the application
of new materials and manufacturing technology, UHMWPE gear accuracy
is higher and higher, the life is getting longer and longer.
Customized according to your requests.
What is UHMW-PE?
UHMW polyethylene is a high crystalline high density polyethylene
polymer with an average molecular weight in the 3.1 to 5.0 million
range. Because of its high molecular weight, it is categorized as
Ultra High Molecular Weight polyethylene.
Products of UHMW polyethylene exhibit an exceptional combination of
outstanding properties. It has high abrasion resistance, low
coefficient of friction, self-lubrication, non-adherent surface,
excellent chemical fatigue and impact resistance, and good noise
dampening properties. Its outstanding characteristics include very
high resistance to wear and abrasion, and high performance at
extremely low temperatures (liquid nitrogen -259 degrees C. UHMW
starts to soften and lose its abrasion resistance characteristics
around 185 degrees F.
Because UHMW-PE has a relatively high expansion/contraction rate
when subjected to temperature changes, it is not recommended for
close tolerance applications in these environments.
