Polytetrafluoroethylene filled products: Composite materials made by mixing polytetrafluoroethylene (PTFE) with glass fiber, carbon fiber, carbon powder, copper powder and other materials. By adjusting the type and proportion of fillers, the specific properties of polytetrafluoroethylene can be improved.
Performance characteristics
1. Enhance mechanical properties: For instance, glass fiber filling can increase tensile strength and wear resistance, while carbon fiber filling can enhance rigidity, making it suitable for scenarios with high friction, high pressure, and those requiring lightweight and high strength.
2. Improve thermal conductivity: Adding thermal conductive fillers such as carbon powder or copper powder can effectively enhance the thermal conductivity of polytetrafluoroethylene, meeting the requirements of high-temperature conduction and heat dissipation.
3. Reduce the coefficient of thermal expansion: After filling with certain materials, the coefficient of thermal expansion of polytetrafluoroethylene is reduced, and its dimensional stability is improved, making it suitable for precision components and applications with high precision requirements.
