GENERAL DESCRIPTION
Duratron ® T 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 Duratron ® T 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).
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.
DURATRON ® GLASS-REINFORCED PAI Duratron T5030 PAI (Extruded)
Duratron ® T5030 is 30% glass reinforced, extruded PAI. It is ideal for higher load structural or electronic applications. This grade is similar in composition to Duratron ® T5530 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 Duratron ® T5030 PAI is typically only available in thin sheets and small diameter rods. Check with us for availability of T5030 in the size you need.
Duratron T5530 PAI (Compression Molded)
Duratron ® T5530 compression molded PAI is the same formulation as 5030, but has been made into stock shapes using a different manufacturing process. The resulting material is similar to T5030, but has slightly different mechanical properties (see datasheet below).
Compression-molded Duratron ® T5530 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 T5530 in the size you need.
