The benefits of Torlon 4203
Withstands high temperatures (+ 260ºC).
Only 4% of the tensile stress is lost after 2000h at + 200ºC.
UL index 220ºC.
Extremely low friction and abrasion in grades filled with
PTFE or graphite.
Extremely low thermal expansion.
Chemical resistant.
Mechanical strength values are stably high throughout the temperature range.
Torlon 4203 has the best toughness and impact strength of all Torlon PAI grades because of its:
intrinsic high-temperature resistance
high dimensional stability
good machinability.
This PAI plastic is usually used for its electrical insulating ability and its ability to provide numerous possibilities in the field of electrical components. PAI 4203 is therefore used in such things as:
