The Nylon66(Polyamide6.6 with 30% Long Carbon Fiber
Product Model: LFT-PA66-BC03B CF30
Extreme heat resistance
Superior tensile strength
Low creep behavior
Metal replacement ready
LFT-G® PA66 CF30 (Grade: LFT-PA66-CF30-BC03B) is a premium polyamide 66 compound reinforced with 30% long carbon fiber. Engineered for extreme environments, it delivers exceptional heat resistance, superior tensile strength, and ultra-low creep behavior. By forming a rigid internal skeletal network, this LCF30 material outperforms standard short-fiber CF30, making it the ultimate solution for structural metal replacement in global automotive and high-end industrial applications.
To maintain the length of the carbon fiber network and maximize the mechanical properties of LFT-G® PA66-CF30, adhere to these injection molding parameters:

Applications: Where LFT-G® PA66 CF30 Excels
Automotive Under-Hood Components
Ideal for engine covers, transmission mounts, and fluid housings. The PA66 base provides superior high-temperature resistance and chemical tolerance to oils, while the long carbon fibers ensure structural integrity meeting demanding global automotive standards.
Aerospace & Commercial Drones
Used in drone chassis, propeller guards, and aerospace interior brackets. The exceptional strength-to-weight ratio allows for maximum payload capacity and flight efficiency without compromising on impact durability.
High-End Industrial Machinery
Perfect for pump housings, robust gears, and heavy-duty conveyor systems. Its low creep under prolonged mechanical stress ensures long-term reliability in harsh industrial and manufacturing environments.
People Also Ask (FAQ)
Q: Is PA66 CF30 stronger than aluminum?
A: Yes, in many applications. LFT-G® PA66 with 30% long carbon fiber offers a specific strength (strength-to-weight ratio) that matches or exceeds die-cast aluminum, while reducing weight by up to 40% and eliminating the need for anti-corrosion treatments.
Q: What is the difference between PA6 CF30 and PA66 CF30?
A: While both are excellent reinforced polyamides, PA66 CF30 offers higher thermal stability (melting point around 260°C vs. 220°C for PA6), lower moisture absorption, and slightly higher rigidity. It is preferred for components exposed to higher temperatures and stress.
Q: Do I need special equipment to injection mold long carbon fiber PA66?
A: Standard injection molding machines can be used, but to preserve the long fiber structure, we recommend using a low-compression screw, generous gate sizes, and avoiding excessive back pressure or high screw RPM during processing.
