With superior mechanical properties, exceptional thermal performance, and excellent chemical resistance, PA12 LCF40 is well-suited for high-performance applications in industries such as automotive, aerospace, industrial manufacturing, and consumer goods.
Characteristics and Values for Enhanced Performance
Carbon Fiber Content: 40%
The 40% carbon fiber content in PA12 LCF40 provides a substantial increase in mechanical properties, including tensile and flexural strength. This allows the material to handle even higher stresses and loads while maintaining a lightweight profile. As a result, PA12 LCF40 is ideal for applications that demand maximum strength and rigidity without significantly adding weight.
Tensile Strength: ≥ 140 MPa
With the higher carbon fiber content, PA12 LCF40 exhibits excellent tensile strength, enabling it to endure greater mechanical loads without deformation. This makes it especially suitable for high stress applications requiring maximum load-bearing capabilities.
Flexural Strength: ≥ 240 MPa
PA12 LCF40’s superior flexural strength ensures resistance to bending and deformation, making it an ideal choice for structural components exposed to heavy or dynamic loads over time.
Impact Strength: ≥ 40 kJ/m²
PA12 LCF40 has improved impact resistance compared to lower carbon fiber versions. This means it can better absorb and withstand sudden shocks and impact forces, contributing to the longevity and durability of parts in high-stress, high impact environments.
Thermal Properties
Heat Deflection Temperature: Approximately 220°C
PA12 LCF40 retains its structural integrity at even higher temperatures, making it suitable for applications in extreme heat environments, such as engine compartments, industrial machinery, or high-temperature tooling.
Long-Term Service Temperature: Up to 150°C
With an increased long-term service temperature, PA12 LCF40 can consistently perform in environments that experience moderate to high temperature fluctuations, ensuring reliability for extended periods in demanding applications.
Chemical Stability
PA12 LCF40 offers exceptional resistance to a wide range of chemicals, including oils, fuels, lubricants, and solvents. This makes it particularly suitable for automotive, industrial, and other sectors where exposure to harsh chemicals is common. Its low moisture absorption further enhances its dimensional stability and performance in humid or wet conditions.
Processing Characteristics
PA12 LCF40 can be processed using conventional manufacturing methods such as injection molding, extrusion, and 3D printing. Despite the increased carbon fiber content, it maintains excellent flow properties, enabling the production of high-precision, high-quality components, even with complex geometries.
Other Characteristics
Low Water Absorption
PA12 LCF40’s low moisture absorption ensures that it maintains dimensional stability and reliable performance even in humid or wet environments, making it ideal for parts exposed to moisture or harsh conditions.
Superior Wear Resistance
With 40% carbon fiber content, PA12 LCF40 exhibits excellent wear resistance, making it ideal for components that face high wear and tear. This enhances the material’s lifespan and makes it a good choice for demanding industrial applications.
Applications
Automotive Industry:
PA12 LCF40 is used in high-performance structural components, brackets, housings, and other critical automotive parts that require superior thermal stability, strength, and durability under heavy loads.
Aerospace and Industrial Manufacturing:
In aerospace and industrial sectors, PA12 LCF40 is used for parts such as gears, bushings, and structural components that demand exceptional stiffness, wear resistance, and the ability to handle high mechanical loads in harsh conditions.
Consumer Goods:
This material is also ideal for producing high-strength, lightweight consumer products like tools, sporting equipment, and accessories that require both durability and performance in challenging environments.

Thermal Stability of PA12-LCF
PA12-LCF (carbon fiber reinforced polyamide 12) has better thermal stability than standard PA12. The addition of carbon fiber increases the heat distortion temperature (HDT) of the material, allowing it to maintain good structural integrity in high-temperature environments. At the same time, carbon fiber also improves the thermal conductivity of PA12-LCF, helping to better dissipate heat and enhancing its durability under high temperature conditions. Overall, the thermal stability of PA12-LCF makes it suitable for applications requiring high strength and heat resistance, such as the automotive, aerospace and electronics industries.
