Polyphthalamide (PPA) and PPA Blends

PPA and PPA Blends

High-temperature Compound With Low Moisture Absorption

Polyphthalamide (PPA) is characterised in particular by high heat resistance and the lowest moisture absorption combined with high chemical resistance. The semi-aromatic and semi-crystalline polyamide PPA has good resistance to creep, fatigue and warpage as well as good dimensional stability. Good tensile strength and stiffness are also part of the properties profile of this material.

Excellent Metal Substitute

Durch seine zuvor genannten Eigenschaften ist PPA gut für Anwendungen mit hoher Temperaturbelastung in der Automobilbranche und mechanisch hochbeanspruchte Teile geeignet. Es besteht den Einsatz in chemischen Umgebungen und bei hohen Temperaturen. Daher wird es gern für Anwendungen in der Automobil- und Elektronikindustrie als Ersatz für Metalle genutzt. Komponenten aus PPA tragen durch ihre geringere Dichte zu einer Gewichtsreduktion bei, ein Aspekt, der im Automobilbau an Bedeutung gewonnen hat.

Other areas of application are technical parts for brakes and clutches as well as vehicle interiors. Bobbins, connecting plugs and connectors for electrical engineering as well as dimensionally stable housings and hot-water-resistant functional components in the sanitary and household appliance industry are among the most common application segments.

We offer you a selection of grades with up to 60% glass fibre reinforcement.

These PPA Grades Are Available from K.D. Feddersen
