Ultra High Molecular Weight Polyethylene Tubing

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 weight of molecule ranging from 3 to 6 million, compared to 300,000 to 500,000 for (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.
