What’s it?

Heat stabilized PA12 CF40 refers to Polyamide 12 (Nylon 12) reinforced with 40% carbon fiber and enhanced with heat stabilization additives. This composite material combines the inherent properties of PA12 with the mechanical strength and thermal stability provided by carbon fibers, making it suitable for demanding applications where high performance under elevated temperatures is required.

Features

1. Mechanical Strength: The addition of 40% carbon fiber significantly enhances the mechanical properties of PA12. Carbon fibers are lightweight yet extremely strong, improving tensile strength, stiffness (Young’s modulus), and impact resistance compared to unfilled PA12. This makes PA12 CF40 suitable for structural components subjected to high mechanical loads.

2. Thermal Stability: Heat stabilization additives further enhance the material’s thermal resistance. PA12 40%CF  exhibits excellent dimensional stability and retains its mechanical properties over a wide temperature range, making it suitable for applications exposed to elevated temperatures without significant loss of performance.

3. Chemical Resistance: PA12 is known for its resistance to oils, greases, fuels, and many chemicals. The incorporation of carbon fibers typically does not compromise this resistance, allowing PA12 CF40% to maintain its integrity in harsh industrial environments.

4. Electrical Conductivity: While not typically conductive enough for electrical applications, PA12+CF40 may exhibit some level of electrical conductivity due to the presence of carbon fibers. This property can be advantageous in applications requiring static dissipation or where slight conductivity is beneficial.

5. Dimensional Accuracy: The combination of PA12’s inherent low moisture absorption and carbon fiber reinforcement contributes to excellent dimensional stability. This is critical for maintaining tight tolerances and dimensional accuracy in molded parts over time.
