488 PTFE

Rulon® 488 is a dull turquoise material originally developed for use with painted surfaces. It has been used in veneer dryer bearings in the plywood industry.

Its almost universal chemical resistance enables it to withstand corrosives and acids sometimes present in trace amounts in these environments.

Rulon® 488 also has a higher load capacity than Rulon® J and better abrasion resistance than both Rulon® J and Rulon® 142.

The material is molded and precision machined from high performance polymers as PTFE and filled PTFE composites. Its excellent wear resistance, especially in extremely dry environments, make it a material of choice in hydrogen and natural gas compressors.
