Engineering Thermoplastics
PPA Standard — Polyphthalamide Standard
PPA is a semi-aromatic polyamide that bridges the gap between conventional polyamides and high-performance polymers. It offers superior mechanical properties, stiffness, and thermal resistance compared to standard nylons, along with good chemical resistance.
