Material
Carbon Fiber PPA
Carbon fiber PPA is a high-performance composite that pushes heat resistance and dimensional stability well beyond standard carbon fiber nylon. It is suited to demanding engineering applications exposed to elevated temperatures.

About
Carbon fiber PPA reinforces polyphthalamide – a high-temperature nylon variant – with carbon fiber. This extends heat resistance meaningfully beyond standard carbon fiber nylon while absorbing even less moisture than PA12, therefore helping parts maintain their stiffness and dimensional stability in hot or humid environments.
It offers high strength and stiffness, along with strong resistance to wear, creep, and long-term chemical exposure.
As with other carbon-fiber composites, reinforcement generally comes with some reduced toughness compared to unreinforced nylon, though toughness and abrasion resistance are generally retained even at elevated temperatures.
Carbon fiber PPA is a fitting choice for structural components, automotive and aerospace parts, and electronics housings operating in demanding thermal or chemical environments.
