Torlon is for Punishing Environments
Wednesday, June 16th, 2010by Dave Biering
Torlon® is a high-strength plastic, and is among the most expensive on the market. Torlon can be injection molded, compression molded, and extruded, and is ideally suited for severe service environments. Applications include pump components, valve seats, bearings, rollers, high temperature insulators, electronic equipment, compressor components, and bearing cages.
The main characteristics of Torlon are a high maximum allowable service temperature, excellent mechanical strength and creep resistance over a wide range of temperatures, extremely low coefficient of linear thermal expansion, low flammability, exceptional resistance against high-energy radiation, moderate chemical and hydrolysis resistance, and excellent UV resistance. And Torlon is excellent at maintaining physical properties.
We’ve got a range of Torlon grades available for your application:
● 4203 and 4503 – structural/insulating grade offering good insulating properties, low thermal expansion, moderate coefficient of friction
● 4301 and 4501 – extrusion most popular – gives excellent wear, reduced coefficient of friction, little to no stick slip, flex modulus over 1 million psi
● 4540 – bearing grade for extreme wear life – insulating materials (primarily structural): aluminum, and stainless steel
● 5530/4XG – excellent electrical insulating properties, good wear resistance, abrasive towards mating surfaces, moderate dynamic coefficient of friction
● 4XCF – another good bearing material in hi-temp applications, high stiffness, lowest coefficient of thermal expansion of any standard polymer shape, non-abrasive
