介绍 |
Duratron® T4501 compression molded PAI is well suited for
general purpose wear and friction parts. It has a higher
compressive strength and can therefore carry more load than
Duratron® T4540. It is similar in composition to Torlon 4301 PAI,
and selected when larger shapes are required. Duratron® 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® 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® PAI is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C). Data provided by Quadrant Engineering Plastic Products from tests on stock shapes and parts produced by Quadrant EPP. |
