An engineering polymer that provides high stiffness and strength at high
temperatures has been added to Farnell's industrial catalogue. Ideal
for applications often considered too demanding for thermoplastics,
Torlon shows good dimensional stability and chemical and radiation
resistance. It maintains its strength under continuous exposure to high
temperatures between 230$C and 260$C, with an operating temperature range
extending down to -190$C.
Torlon can be injection moulded, extruded or compression moulded, and
offers a range of options to designers. Two grades are available: the
4203 electrical grade is suitable for repetitively used precision
mechanical and load-bearing parts such as connectors and switches.
Meanwhile, the 4301 bearing grade has enhanced wear resistance and a
lower coefficient of friction, making it ideal for fabrication of moving
parts including bearings, thrust washers and valve seats.
