A new family of wear and friction acetal (POM) compounds from RTP Co., Winona, Minn., reportedly represent an advancement over other wear-resistant compounds. APWS Plus compounds utilize a proprietary polymeric alloy that is said to improve wear-and- friction resistance resulting in moving and sliding parts with longer lifecycles and reduced maintenance costs. Also claimed is no plate-out, preventing mold corrosion and frequent mold cleaning which results in production downtime.
APWA Plus compounds contain no PTFE, are 100% halogen-free and are fully compliant with RoHS regulations. The use of the proprietary alloy as a lubricant is said to result in a lower specific gravity and more stable lubricant raw material supply which contributes to the competitiveness and reliability of these new compounds. Colorability and FDA compliance are added benefits. Says global business manager for wear & friction materials Gregg Newby, “As RTP Company does in all of its compound technologies, our wear and friction resistant compounds benefit from our ability to draw upon the widest range of resins and additives to improve optimal customer solutions.” APWA Plus compounds are available in additional resins systems used for wear-resistant applications such as nylon and PC.
