Product Details

Ultra High Molecular Weight Polyethylene is the highest quality polyethylene available for use in harsh environments and for a variety of applications. The applicability is very good under many difficult application conditions.


High molecular weight is a distinctive feature of this polymer, with a molecular weight of 3 to 6 million, while high density polyethylene resin is only 300,000 to 500,000. This difference is to ensure that the ultra high molecular weight polyethylene has sufficient strength to achieve the wear and impact resistance that is not possible with other lower polymer products. The ultrahigh molecular weight of ultrahigh molecular weight polyethylene means that it does not melt and flow to the liquid, so the processing method is derived from powder metal technology. Traditional plastic processing techniques, such as injection molding, blow molding, and heat setting, cannot be applied to ultra high molecular weight polyethylene. Extrusion is the most common processing technique used in this type of resin, resulting in a tougher product.
