GENERAL DESCRIPTIONTorlon ® 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 5530 PAI (Compression Molded)
Torlon ® 5530 is 30% glass reinforced, compression molded 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.
Torlon ® 5530 compression molded PAI is the same formulation as extruded Torlon 5030 PAI, but has been made into stock shapes using a different manufacturing process. The resulting material is similar to 5030, but has slightly different mechanical properties. See Torlon 5030 Extruded PAI datasheet for comparison, or these two glass-reinforced grades side-by-side here.
Compression-molded Torlon ® 5530 is typically available only in larger diameter rods (in short lengths), thicker sheets, and large (but short length) tubes. Check with us for availability of 5530 in the size you need.
