PA12 LCF50 – High-Performance Long Carbon Fiber Reinforced Nylon 12
-
What is PA12 LCF50 Material?
LFT-G® PA12 LCF50 is a high-performance engineering thermoplastic composed of Nylon 12 (PA12) reinforced with 50% long carbon fibers (LCF). This advanced compound delivers exceptional stiffness, outstanding chemical resistance, and ultra-low moisture uptake - far surpassing conventional short-fiber and glass-reinforced alternatives in demanding environments where reliability is critical.
The continuous carbon fiber network within each pellet ensures superior load transfer and fiber retention after molding, resulting in an exceptional strength-to-weight ratio, inherent electrical conductivity for ESD protection, and long-term stability under cyclic loading, chemical exposure, and extreme thermal conditions.

Key Material Advantages
Ultra-Low Moisture Absorption
PA12 base resin absorbs up to 90% less moisture than PA6, ensuring unmatched dimensional stability and property retention in humid or wet environments.
Superior Chemical Resistance
Excellent resistance to fuels, oils, greases, salts, and a wide range of solvents - ideal for automotive fluid-contact and industrial chemical environments.
High Stiffness & Strength
50% continuous carbon fiber delivers tensile strength > 220 MPa and flexural modulus > 15 GPa - rivaling die-cast metals at a fraction of the weight.
Inherent Electrical Conductivity
Volume resistivity below 10³ Ω·cm provides reliable ESD protection, eliminating the need for external anti-static additives or coatings.
Excellent Fatigue & Creep Resistance
The continuous 3D carbon network ensures minimal deformation under sustained loads and outstanding endurance against cyclic stress.

Q: Why choose PA12 LCF50 over standard PA6 or PA66 carbon-fiber grades?
A: PA12 LCF50 offers ultra-low moisture absorption - up to 90% less than PA6 - ensuring consistent dimensional stability and mechanical properties in humid environments. It also provides superior chemical resistance to fuels, oils, and solvents, making it the preferred choice for fluid-contact applications where PA6-based materials would degrade.
Q: What makes the long carbon fiber architecture superior to short-fiber carbon compounds?
A: The continuous carbon fiber network in PA12 LCF50 provides efficient load transfer across the entire part, delivering up to 95% higher impact strength, 35% greater flexural modulus, and significantly improved fatigue endurance compared to short-fiber PA12 CF50. This translates into thinner, lighter parts without sacrificing durability.
Q: What are the recommended drying conditions for PA12 LCF50 before injection molding?
A: Dry PA12 LCF50 at 80–90°C for 3–5 hours using a dehumidifying dryer. Ensure moisture content is below 0.05% to prevent surface defects (splay, silver streaks) and maintain optimal mechanical properties. PA12 is less hygroscopic than PA6, but proper drying remains essential for consistent molding results.
