Braskem UTEC® 3040 Ultra High Molecular Weight Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); UHMW PE (Ultra High Molecular Weight PE)
Material Notes:	Description: UTEC3040 is an Ultra High Molecular Weight Polyethylene with a molecular weight about 10 times higher than High Density Polyethylene (HDPE) resins. This extremely high molecular weight yields several unique properties to this polymer such as high abrasion resistance and impact strength and low coefficient of friction, what makes it a self-lubricating material. Applications: Applications which require high impact resistance – technical and porous parts, filters, compression molded sheets. Information provided by Braskem.
