Frequently Asked Questions
How does PA46 compare to PPA?
PA46 has a higher melting point (295°C vs 260-310°C for PPA) and better flowability for thin-wall molding. PPA generally has lower moisture absorption and better dimensional stability. PA46 is preferred for applications requiring both high temperature and high toughness; PPA for applications requiring maximum dimensional stability at temperature.
