Poly-Texx® 350 is an abrasive resistant polymer that is FDA compliant in its unfilled state. It’s natural color is white, but is available in black and other colors at special request. Typical applications include sleeve and flanged bearings for industrial and manufacturing bearing applications. Custom and standard profiles for conveying environments. Custom machined components for high wear material handling applications. Its main attributes are impact and abrasion resistance. Its self-lubrication properties and low cost makes Poly-Texx® 350 a great choice for many demanding applications.
