Polyphthalamide (PPA) is a type of engineering plastic that is used in a variety of applications. It is a semi-crystalline thermoplastic that offers excellent mechanical properties, chemical resistance, and thermal stability. PPA is often used in automotive, electrical, and electronic components, as well as in medical and consumer products. It is also used in the production of high-performance components for aerospace and defense applications. PPA is known for its excellent dimensional stability, low moisture absorption, and good electrical insulation properties. It is also resistant to a wide range of chemicals, including acids, bases, and solvents.
PPA is available in a variety of grades, including glass-filled, mineral-filled, and flame-retardant grades. It is also available in a range of colors, including black, white, and gray. PPA is typically processed using injection molding, extrusion, and blow molding.
Some of the major companies in the PPA market include BASF, Solvay, Celanese, SABIC, and DuPont. Show Less Read more
