Chemical resistance and characteristics

Chemical resistance

Le PPA présente une excellente résistance aux huiles moteur à haute température, aux graisses industrielles et aux carburants. Sa faible absorption d'humidité garantit une stabilité dimensionnelle supérieure. Sensible aux acides forts concentrés et bases à chaud.

Recommended applications

Pièces sous capot moteur haute T°, connecteurs électriques haute T° (> 150 °C), boîtiers de capteurs automobiles, pièces de transmission, équipements industriels haute performance, remplacement des thermodurcissables
