Poly-Texx® 350GF

Poly-Texx® 350GF is one of the most abrasive resistant polymer materials available.  It’s natural color is blue, but is available in black and other colors at special request.  Typical applications include sleeve and flanged bearings for industrial and manufacturing bearing applications.  Heavy gauge Bushings and slide plates for the timber and railroad industry. Custom machined components for high wear material handling applications.  Its main attribute is its abrasion resistance.  Its self-lubrication properties, superior abrasion resistance and high impact strength make Poly-Texx® 350GF a great choice for many demanding bearing and wear applications.
