Duratron T4503 compression molded PAI is commonly used for dies and patterns of formed metal parts, or as thermal insulators and isolators. It is similar in composition to Duratron T4203 PAI, and selected when larger shapes are required.
Duratron 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 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. Duratron is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C).
