PPA (Polyphthalamide) is polyphthalamide.PPA is a kind of thermoplastic functional nylon with both semi-crystalline structure and non-crystalline structure. It is prepared by polycondensation of phthalic acid and phthalenediamine. It has excellent thermal, electrical, physical and chemical resistance and other comprehensive properties.

What is the PPA material? PPA is polyphthalamide. PPA is a kind of thermoplastic functional nylon with both semi-crystalline structure and non-crystalline structure. It is prepared by polycondensation of phthalic acid and phthalenediamine. It has excellent thermal, electrical, physical and chemical resistance and other comprehensive properties. It still has excellent mechanical properties, including high rigidity, high strength, high dimensional accuracy, low warping and stability, fatigue resistance and creep resistance, under the harsh working environment of continuous high temperature, humidity, oil pollution and chemical corrosion at 200℃. What is the PPA-LGF? Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with lower price plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properfies of engineering polymers, and increase the durability by forming long fibers to form a long - fiber - reinforced internal skeleton networkl. Performance is preserved in a wide range of environments. What is the difference compared with Short glass fiber compounds? What is the application of PPA-LGF? Bicycle accessories Mechanical parts Drive belt pulley For other applications filed please contact us, and we will give you technical support.
