PA has the advantages of high mechanical strength, high softening
point, good wear resistance, self-lubrication, cushioning, sound
deadening, excellent oil and chemical corrosion resistance, and
good electrical insulation. Because of these superior performances,
PA composite has already replaced some metals being as structural
materials.
PPA has advantages of high modulus, high rigidity, high performance
price ratio, low water absorption rate, dimensional stability and
excellent weld-ability etc. PPA material has excellent overall
properties which enable its well performance under thermal,
electrical, physical and chemical condition. PPA still maintains
high rigidity & strength, as well as excellent dimensional
accuracy & stability even under high
temperature.
