RTP COMPANY INTRODUCES COST-EFFECTIVE COMPOUNDS CONTAINING PERFLUOROETHER
31 January 2000 - RTP Company

Perfluoropolyether synthetic oil has a successful 40-year history as a topical lubricant. Now, RTP Company has perfected a method to disperse this modifier into thermoplastics to produce innovative, cost-effective solutions for wear-resistant applications.

When used as a modifier in specialty compounds, PFPE significantly improves the wear resistance of crystalline resins with little to no effect on specific gravity. With common loading levels of just 0.1% to 1.0%, these compounds perform similarly to those with 15 to 20% loadings of PTFE.

RTP Company's new PFPE compounds are generally more cost-effective than compounds containing PTFE. In addition to material cost savings, they reduce processing costs by eliminating die cleaning and its associated downtime.

Typical benefits include
Eliminating plate-out associated with PTFE
Improving wear resistance and reduce coefficient of friction at low modifier levels (less than 1.0%)
Improving processing by enhancing melt flow, increasing throughput, and acting as a mold release
Improving fatigue resistance, particularly important for gear applications
Minimizing marring and scratching of polymer surfaces and reduce or eliminate squeaks.
Choose RTP Company's PFPE compounds for medical devices such as catheters; increased extrusion throughput (e.g. tubing or corrugated pipes); gears, pulleys, bushings, bearings, and seals; "No Silicone Permitted" applications; and existing PTFE applications where price or plateout are concerns.
