Introduction: Carbon Fiber Redefines the Performance Boundaries of Engineering Plastics

The introduction of Carbon Fiber (CF) has propelled the performance of engineering plastics to unprecedented heights. It serves not only as a reinforcing agent but also as a functional component. Renjie Plastics utilizes specialized sizing agents and advanced compounding processes to ensure excellent dispersion and interfacial bonding of carbon fiber within the nylon matrix. This results in superior specific strength and specific modulus, as well as enhanced fatigue resistance and creep resistance compared to glass fiber-reinforced systems.

More importantly, when carbon fibers form a continuous conductive network, the material gains entirely new functional dimensions: from antistatic and conductive properties to effective Electromagnetic Interference (EMI) shielding. This achieves functional integration, where a single structural component simultaneously handles conductivity, shielding, or thermal management. This paves the way for miniaturization, integration, and high-reliability design in electronic products.

Core Advantages of the Carbon Fiber Series

• High Strength & Stiffness: Significantly higher specific strength and specific modulus than glass fiber-reinforced systems.

• Dimensional Stability: Extremely low Coefficient of Thermal Expansion (CTE) ensures precision and stability.

• Functional Integration: Tunable conductivity and effective EMI shielding performance.

• Wear Resistance & Thermal Conductivity: Inherently low friction coefficient combined with higher thermal conductivity.

Carbon Fiber Series: An Integrated Future Defined by Performance Data

The performance of this series can be precisely tailored by controlling the content and type of carbon fiber. We offer a wide range of options from standard modulus to high modulus carbon fibers to meet your specific requirements for stiffness, strength, conductivity, and cost.

Exceptional Stiffness and Strength

Nylon composites filled with 30% carbon fiber can easily achieve a flexural modulus exceeding 20,000 MPa and tensile strength surpassing 200 MPa.

Tunable Conductivity

Surface resistivity can be engineered across a broad range of 10¹ to 10⁹ Ω/sq, satisfying diverse application needs ranging from ESD protection to structural conductivity.

Effective EMI Shielding

At a frequency of 1 GHz, shielding effectiveness can reach 30–50 dB, providing sufficient internal protection for most consumer electronics and industrial electronic equipment.

Low Friction and High Thermal Conductivity

The incorporation of carbon fiber also imparts a lower friction coefficient and higher thermal conductivity to the material, making it ideal for wear-resistant components and heat dissipation scenarios.
