Torlon PAI from Solvay is one of the outstanding polymers for high temperature applications. Torlon is available in various forms and with different enhancements to meet diverse applications such as bearings, dielectric insulators and structural components. Torlon’s physical properties maintain very high values even at the maximum operating temperatures.

Tivar HOT is a unique UHMW grade that has a dramatically higher continuous operating temperature (275F) than standard UHMW. Tivar HOT still has excellent wear and abrasion resistance, doesn’t absorb moisture, has excellent chemical resistance and meets FDA, USDA and 3A guidelines. We have found this product to be excellent for higher temperature zones in food processing and packaging equipment but it has also proven to be a great material in down-hole oil drilling applications!
Pretty diverse material. If you need excellent abrasion resistance, low friction, self lube bearing material with all of the other attributes mentioned, consider Tivar HOT from TriStar! And while you are looking around the site – stop by the Video Learning Center for some more information!
High temperature polymers have been around for many years but industry is just now learning the value of these unique materials. Imidized materials like Celazole (PBI), Vespel and Meldin (PI) and Torlon (PAI) are able to maintain high physical strength in the 500-750F operating range. These materials have excellent wear properties and are available in many blends which enhance friction/wear properties, structural strength and thermal stability.
