The Champion of ESD Protection & Surface Aesthetics
LFT-G® PA66 LCF30 fundamentally redefines the entry point to long carbon fiber thermoplastics. While providing substantial structural stiffness (14,588 MPa modulus), its optimized 30% fiber loading is specifically engineered for manufacturers who cannot compromise on surface finish. This formulation mitigates the severe surface abrasions and "floating fiber" defects commonly associated with heavily loaded carbon composites. Crucially, it retains the inherent electrical conductivity of carbon, making it a premium ESD-safe material with the absolute lowest density (1.23 g/cm³) in the LCF spectrum.
Typical values shown above are for quick engineering reference. For parts requiring external aesthetic finish, strict mold temperature control during injection is mandatory to prevent surface defects.

Injection Processing Guidelines for PA66 LCF30
Dehumidifying
100–120°C / 4–6h
Strictly dry to < 0.1% moisture
Melt Temp
270–299°C
Excellent melt flowability
Mold Temp
80–120°C
CRITICAL for glossy surface finish
Injection Speed
Medium to Fast
Prevents premature fiber freezing
Engineering Advisory for Surface Aesthetics: To eliminate the "floating fiber" (rough surface) effect common in carbon composites, a high mold temperature (closer to 120°C) and rapid injection speed are highly recommended. This allows the PA66 matrix resin to rapidly migrate to the mold surface before the carbon fibers freeze.
Engineered for ESD Safety & External Aesthetics
PA66 LCF30 perfectly resolves the conflict between robust structural reinforcement and the need for flawless aesthetics. It is the premier choice for exterior components and sensitive electronic environments where anti-static properties are strictly regulated.
Semiconductor & Electronic Handling Trays
Engineering challenge: Automated IC assembly lines require handling trays that absolutely will not warp under thermal stress, while demanding strict ESD limits (10&sup4; - 10&sup6; Ω) to prevent frying microchips with static electricity.
Why PA66 LCF30: The long carbon fibers lock the tray's dimensions in place, eliminating warpage entirely. The inherent conductivity of the carbon network effortlessly dissipates static charges, making it superior to temporary anti-static spray coatings.
Explosion-Proof Industrial Enclosures
Engineering challenge: Sensors and communication devices in coal mines, oil rigs, and chemical plants must be housed in materials that absolutely cannot build up and discharge electrostatic sparks.
Why PA66 LCF30: This compound effortlessly meets ATEX explosion-proof material directives via its permanent static dissipation properties. Furthermore, its 14,558 MPa modulus ensures the internal electronics survive severe crush impacts.
Premium Handheld Devices & Power Tool Housings
Engineering challenge: High-end professional power tools require housings that can survive repeated concrete drops, feel incredibly lightweight to prevent user fatigue, and project a premium, flawless visual appearance.
Why PA66 LCF30: It boasts an ultra-low 1.26 g/cm³ density. Because the fiber loading is restricted to 30%, it allows the PA66 resin to form a beautiful, smooth external skin during molding, while the long fibers inside provide catastrophic drop-impact resistance (22 kJ/m²).
