Most PPA are filled with glass fiber or carbon fiber to enhance stiffness for high-temperature applications. As a result, PPA is often used in applications in place of metal or higher-priced thermoplastic.

LFT®PPA-NA-LGF is a 20%-60% long glass fiber reinforced, heat stabilized polyphtalamide PPA, with improved friction properties, high heat deflection temperature, very high flexural modulus and low moisture absorption. It displays an excellent retention of properties in a wide temperature range as well as outstanding creep and fatigue resistance. LFT®PPA-NA-LGF has a pellet length of 5-25mm and can be easily processed on most injection-molding machine.
What Is the Difference Between
Polyphthalamide (PPA) and Nylon?
The difference between PPA and Nylon is that PPA is a type of Nylon.
Polyamide, or Nylon, is a primary high-performance engineering thermoplastics class because of its excellent balance of properties. It is formed by condensing identical units and copolymers with different units.
Polyphthalamide (PPA) is a semicrystalline, aromatic polyamide. It is in the polyamide, or nylon, family. Compared to Nylon 6/6, it is stronger, stiffer, less sensitive to moisture, and has higher thermal capabilities. In addition, it has significant resistance to chemical fatigue and mechanical creep.
Applications
For lightweight and high-performance parts to be used in many different applications
