GENERAL PROPERTIESTorlon ® 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 ® 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. Torlon ® is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C).
Depending upon the method used to produce a stock shape (sheet, rod, or tube), the properties of the resulting material can vary. Generally speaking, the best mechanical properties are exhibited by injection molded material. However, the process used is generally defined by the size and shape of the desired material. For example, small diameter rod and thin sheets are extruded -- larger shapes are compression molded. See the following descriptions and properties table for details.
TORLON ® GLASS-FILLED GRADESTorlon 5030 PAI (Extruded)
Torlon ® 5030 is 30% glass reinforced, extruded PAI. It is ideal for higher load structural or electronic applications. This grade is similar in composition to Torlon ® 5530 PAI (compression molded). It is selected for smaller 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 ® 5030 is typically only available in thin sheets and small diameter rods. Check with us for availability of 5030 in the size you need. (see also Duratron T5030 PAI)
Torlon 5530 PAI (Compression Molded)
Torlon ® 5530 is 30% glass reinforced, compression molded PAI. It is ideal for higher load structural or electronic applications. This grade is similar in composition to Torlon ® 5030 PAI (injection molded). 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.
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. (see also Duratron T5530 PAI)
