What is PA66 CF40 ?
LFT-G® BC04B PA66 CF40 is a 40% long carbon fiber reinforced polyamide66(nylon66) Compound, also called nylon66 carbon fiber material. This high-performance carbon reinforced plastic combines a high-temperature polyamide 66 matrix with a 40% loading of long carbon fiber. This reinforced polymer delivers an exceptional combination of stiffness, strength, and thermal resistance. The PA66 CF40 grade is engineered for demanding applications, replacing metal in high-performance automotive, industrial, and aerospace components that operate under high stress and elevated temperatures, offering a premium lightweighting solution without sacrificing performance.
What is the difference between nylon 66 and PA66?
There is no difference; the names are used interchangeably. 'Nylon 66' is the common trade name, while 'PA66' is the scientific abbreviation for the polymer Polyamide 6,6. Both terms refer to the same high-performance thermoplastic known for its excellent mechanical strength, stiffness, and superior thermal and chemical resistance compared to other nylons like PA6. We use PA66 and PA6 as the matrix for this advanced composite.

FAQ
Q: Is carbon fiber nylon abrasive?
A: Yes, the hard carbon fiber makes this composite abrasive to standard tool steel. When processing our LFT-G®PA66 CF40, we recommend using hardened steel molds and nozzles to ensure tool longevity and consistent part quality.
Q:What is the best nozzle for carbon fiber nylon ?
A: For long fiber materials like our LFT-G®PA66 CF40, a bigger nozzle and gate (typically >5mm) are recommended during injection molding. This minimizes fiber breakage, ensuring the best mechanical performance in the final part.
Q: Is nylon carbon fiber conductive?
A: Yes, this carbon fiber reinforced nylon is electrically conductive due to the carbon fiber network within the polymer. This property makes it suitable for applications requiring electrostatic discharge (ESD) protection or EMI/RFI shielding.
