Low-Friction PPA CF30 PTFE Raw Materials Overview
PPA CF30 PTFE Raw Materials are polyphthalamide (PPA)-based composites containing 30% carbon fiber and 10% PTFE, specifically engineered for high-speed friction components like mechanical gears. Utilizing fiber-lubricant synergistic modification technology, this material achieves an ultra-low friction coefficient of 0.08-0.12 and 5× the wear resistance of standard PPA while maintaining excellent heat resistance, effectively solving noise and wear issues in high-speed applications.

Surface Resistivity Comparison
Conductors < 10⁵ Ω/sq. Antistatic Materials 10⁵ ~ 10¹² Ω/sq. Insulators > 10¹² Ω/sq. Static-Dissipative 10⁶ ~ 10¹¹ Ω/sq. *Key Influencing Factors Humidity: Increased moisture can reduce resistivity (e.g., in polymers). Temperature: Affects carrier mobility (↑ heat may lower semiconductor resistivity). Surface Contamination: Dust/oils alter readings significantly. Additives: Carbon black, metallic fillers can lower resistivity. *Applications Electronics: Antistatic materials (10⁶–10⁹ Ω/sq) prevent electrostatic discharge (ESD). Aerospace: Composites must control resistivity to avoid charge buildup. Medical Devices: Insulating materials (>10¹² Ω/sq) ensure patient safety. *Examples Polypropylene (PP): ~10¹⁶ Ω/sq (excellent insulator). Carbon Fiber Composites: 10³–10⁶ Ω/sq (static dissipation). ESD Flooring: 10⁶–10⁹ Ω/sq.
Get to Know Carbon Fibers
The table presents key performance data of carbon fiber grades. T300, with a tensile strength of 3530 MPa and a tensile modulus of 230 GPa, has a relatively low tensile elongation at break of 1.5% and a body density of 1.76 g/cm³. As the grade increases, for example, T700S shows an enhanced tensile strength of 4900 MPa compared to T300, while maintaining the same tensile modulus but with a higher elongation at break of 2.1%. T800S and T1000G both have a tensile modulus of 294 GPa, and their tensile strengths are 5880 MPa and 6370 MPa respectively. T1100G stands out with the highest tensile strength of 7000 MPa and a tensile modulus of 324 GPa. Generally, with the increase in product grade, the tensile strength and modulus tend to rise, while the density remains relatively stable around 1.8 g/cm³.

What are CF Reinforced Thermoplastic Composites?
CF Reinforced Thermoplastic Composites are materials where carbon fibers are incorporated into a thermoplastic matrix. They combine the strength and stiffness of carbon fibers with the processability and recyclability of thermoplastics. For instance, they are used in automotive parts like bumper beams.
-
What are the benefits of CF Reinforced Thermoplastic Composites over traditional composites?
The key benefits include faster production cycles, easier recyclability, and better impact resistance. They also offer design flexibility. An example is in the manufacturing of consumer electronics casings where complex shapes can be achieved more easily.
-
How are CF Reinforced Thermoplastic Composites processed?
Common processing methods include injection molding, extrusion, and compression molding. Injection molding is widely used for mass production. For example, in the production of small components for the medical industry.
-
What industries use CF Reinforced Thermoplastic Composites?
They are utilized in aerospace, automotive, medical, and sports equipment industries. In aerospace, they can be found in interior components. In the medical field, they might be used in prosthetics.
-
How does the carbon fiber content affect the properties of the composites?
Higher carbon fiber content generally leads to increased strength and stiffness but may reduce ductility. A moderate content is often balanced for specific applications. For example, a higher content might be preferred in structural parts of a race car.
-
What are the challenges in using CF Reinforced Thermoplastic Composites?
Challenges include higher material costs, complex processing equipment requirements, and ensuring uniform fiber dispersion. Issues with adhesion between the fibers and the matrix can also arise. An example is in achieving consistent quality in large-scale production.
