Description

The TORLON PAI grades, combining excellent retention of mechanical strength, stiffness and creep resistance over a wide temperature range with extremely low thermal expansion up to 250 C, are top-rank materials for high temperature applications.

TORLON 4203 PAI offers the best toughness and impact strength of all DURATRON PAI grades. Because of its intrinsic high temperature resistance, high dimensional stability and good machinability, this extruded DURATRON PAI grade is very popular for precision parts in high-tech equipment. In addition, its good electrical insulating ability provides numerous possibilities in the field of electrical components.

TORLON 4203 PAI offers the best toughness and impact strength of all DURATRON PAI grades. Because of its intrinsic high temperature resistance, high dimensional stability and good machinability, this extruded DUTARON PAI grade is very popular for precision parts in high-tech equipment. In addition, its good electrical insulating ability provides numerous possibilities in the field of electrical components.

TORLON 4503 PAI is compression moulded material that is similar in composition to TORLON 4203 PAI, and is selected when larger shapes are required.
