7-15 days after shipmentPPA is produced by the polycondensation of aliphatic diamines or aromatic diamines containing benzene rings.
Compared with aliphatic polyamides, the introduction of rigid benzene rings into the molecular chain significantly improves mechanical strength and heat resistance, while reducing water absorption.
Compared with fully aromatic polyamides, semi-aromatic polyamides contain flexible aliphatic segments, resulting in lower melting points and improved processability.
Thanks to its balanced performance, PPA has become one of the most important special engineering plastics, widely used in electronics, electrical components, and the automotive industry.
Glass fiber reinforced PPA composites are considered one of the best materials for metal replacement due to high temperature resistance, high strength, and low density.
Long glass fiber reinforced PPA shows significantly better mechanical properties compared with short glass fiber reinforced materials.
