Poly-Texx® 350SD is one of the most abrasive resistant polymer materials available. Standard color is black. It has 1% carbon filled material ideal for applications requiring both abrasion resistance and static dissipation. Typical applications include sleeve and flanged bearings for industrial and manufacturing bearing applications. With experience, it is easily machined into bearing and wear components for material handling applications. Its main attributes are abrasion and chemical resistance. Available in custom filled formulations, its self-lubrication properties and low cost makes Poly-Texx® 350SD a great choice for many demanding applications.
