Flexural Strength: ≥ 280 MPa
Impact Strength: ≥ 16 kJ/m²
With 60% long carbon fiber, PA6-LCF60 sets a benchmark in stiffness and impact durability, making it ideal for metal replacement in ultra demanding structural applications.
Thermal and Chemical Resistance
PA6-LCF60 retains excellent mechanical performance at elevated temperatures and demonstrates long term resistance to chemically aggressive operating conditions.
Heat Deflection Temperature (HDT): Approx. 160°C
Long Term Service Temperature: Up to 145°C
Chemical Resistance: Excellent resistance to oils, fuels, greases, and weak acids; moderate resistance to alkalis; not compatible with strong acids or oxidizers
Its superior thermal stability ensures consistent performance in automotive under hood zones, aerospace systems, and industrial high heat zones.
Wear Resistance and Processing
The 60% LCF content enhances wear resistance, fatigue endurance, and dimensional accuracy in high load and friction intensive applications.
Wear Resistance: Extremely high – optimized for continuous load and motion
Processing Methods: Injection molding (requires robust long fiber feeding equipment), compression molding
Processing Notes: Low shear mixing is crucial to maintain fiber length; hardened tool steels are strongly recommended due to the composite’s abrasive character
Environmental Adaptability
PA6-LCF60 exhibits minimal water uptake and exceptional dimensional control, even under extreme humidity or temperature fluctuations.
Water Absorption: Significantly lower than standard PA6
Dimensional Stability: Excellent – ideal for tight tolerance parts in variable environments

Strength Comparsion PA6 and PA6-CF
PA6-CF, reinforced with carbon fiber, exhibits significantly higher strength and stiffness compared to unfilled PA6. While standard PA6 offers good toughness and moderate mechanical properties, the addition of carbon fiber enhances tensile and flexural strength, improving load-bearing capacity and dimensional stability. PA6-CF also has lower creep and reduced thermal expansion, making it more suitable for high performance applications where strength and rigidity are critical. However, PA6 retains better elongation and impact resistance, making it more flexible and less brittle under sudden loads.
