Torlon compounds

Torlon 4203L is an unreinforced, all-purpose grade, and it contains 3% titanium dioxide and 0.5% fluoropolymer. It has the best impact resistance and greatest elongation of all the Torlon compounds. 

Torlon 4435 polyamide-imide resin is specifically designed to provide exceptionally low-wear performance in nonlubricated applications even at high pressure and velocity (PV) conditions greater than 50,000 ft lb/(min in). The low coefficient of thermal expansion provides the ability to meet close tolerances over a wide temperature range. Due to its electrically dissipative property, this grade may also be considered for antistatic functions.

The leading global provider of polyamide-imide powders and compounded resins is Solvay Advanced Polymers, LLC, with the resin under the registered trademark Torlon [23]. The major commercial grades are listed below. 

The Swiss company, WW Fischer, offers PTFE (Teflon PTFE or Hostaflon), PBT (Celanex, Crastin, Ultradur or Valox) or PEEK (Victrex) insulator material options in its 405 series of cylindrical connectors according to the requirements of working temperature and other criteria. PEEK is an expensive polymer which tends to be employed when other materials fail to meet the specification requirements of the application. Other Fischer connector types use polyamide-imide (Torlon) or POM (Celcon, Delrin or Hostaform). Elastomeric seals used by Fischer in conjunction with their connectors are made from acrylonitrile-butadiene rubber (NBR N BUNA) or to MIL-P-25732, fluoroelastomer (FPM VITON), polychloroprene elastomer (CR Neoprene), ethylene-propylene diene elastomer (EPDM) and styrene-ethylene-butadiene-styrene thermoplastic elastomer (TPE-S or TPE-O) where each compound is followed by its trade name. Fischer s Swiss competitor, Lemo, manufactures a similar range of connectors including the Redel types which have a plastic body.
