What are Anti-static grade PA12 CF10 compounds?

Anti-static grade PA12 CF10 combines the properties of polyamide 12 (PA12) with 10% carbon fiber (CF10%) to offer specific benefits tailored for applications requiring static electricity dissipation or control. This composite material is designed to address concerns related to static buildup, which can be detrimental in various industrial and electronic environments.

Features of the compounds

1. Static Dissipation: The addition of 10% carbon fiber in PA12 CF10 provides inherent conductivity to the material. Carbon fibers are electrically conductive and help dissipate static charges that can accumulate on surfaces. This feature is crucial in applications where static electricity can damage sensitive electronic components or pose safety hazards.

2. Mechanical Properties: PA12 CF10 retains the mechanical properties characteristic of PA12, enhanced by the addition of carbon fiber reinforcement. Carbon fibers improve tensile strength, stiffness (Young’s modulus), and impact resistance compared to unfilled PA12. The material maintains dimensional stability and durability, making it suitable for structural components and parts subjected to mechanical stress.

3. Thermal Stability: PA12 CF10 exhibits good thermal stability, with carbon fibers contributing to low thermal expansion coefficients. This property is beneficial in applications where dimensional accuracy and stability under varying temperature conditions are required.

4. Chemical Resistance: PA12 is known for its resistance to oils, greases, fuels, and many chemicals. The incorporation of carbon fibers typically does not compromise this resistance, making PA12 CF10 suitable for applications in harsh industrial environments.

5. Anti-static Properties: The primary feature of anti-static grade PA12 CF10 is its ability to dissipate static charges effectively. This property helps prevent static buildup on surfaces, reducing the risk of electrostatic discharge (ESD) events that can damage electronic components or ignite flammable materials in certain environments.
