GENERAL DESCRIPTION
Torlon ® PAI is the highest performing melt processable plastic. It has superior resistance to elevated temperatures. It is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from Torlon ® PAI stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics. Its extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire use range. PAI is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C).
Torlon 4XG 30% Glass-Reinforced (Extruded)
Torlon ® 4XG is 30% glass reinforced, extruded PAI. It is ideal for higher load structural or electronic applications. It is selected for larger shapes or when the greatest degree of dimensional control is required. Applications include burn-in sockets, gears, valve plates, impellers, rotors, terminal strips, and insulators.
Extruded Torlon ® 4XG PAI is typically only available in thin sheets and small diameter rods. Check with us for availability of 4XG in the size you need. (see also Duratron T5030 PAI)
