Ultra High Molecular Weight Polyethylene Manufacturer
What is UHMW-PE?
UHMW-PE stands for
Ultra High Molecular Weight Polyethylene. It is the highest quality
polyethylene (PE) available, designed for heavy duty work and a wide range of
applications. It brings savings in a series of heavy applications. The
ultra-high molecular weight is the secret of the unique properties of this
polymer. Its high-density polyethylene resin has a molecular weight range of 3
to 6 million, compared to 300,000 to 500,000 for high molecular weight (HMW)
resins. That difference is what ensures that this material is strong enough to
withstand abrasion and impact better than lower level poly products. The high
molecular weight of UHMW-PE means that it will not melt or flow as molten
liquid. The processing methods are derived from those metal powder
technologies. UHMW-PE cannot be processed and shaped by conventional plastic
processing techniques (injection molding, blow molding or thermoforming).
Compression molding is the most common conversion process used with this resin
because it produces a stronger, more consistent product.
Ultra High Molecular Weight (UHMW) is a polymer designed with a unique
combination of wear and corrosion resistance, low friction and impact
resistance. UHMW is resistant to chemical attack and moisture absorption and
retains its key physical properties at -30 ° C.
The very high
molecular weight (UHMW) of polyethylene mostly outlives all other materials,
including metals, nylon, urethane and fluoroplastics.
