All products comply with international environmental certification standards, with stable and reliable batch quality, serving global high-end industrial customers. It can be processed into precision finished parts via hot pressing, CNC machining, laser cutting and other mature processes, widely serving high-end industrial fields with extreme temperature, friction and radiation requirements.
Product Processing Advantages
Vespel SP-211 is an upgraded filled composite version of pure polyimide. The synergistic filling of graphite and PTFE perfectly optimizes the friction and wear performance of PI materials, solving the defects of poor self-lubrication and high wear of pure polyimide parts. Different from traditional mold pressing processing, 3-axis and 5-axis CNC machining enables Vespel SP-211 machined parts to achieve ultra-precise dimensional control and complex structural molding, including thin-wall structures and deep-hole parts that cannot be completed by traditional processes.
We adopt the processing mode of combining mold pressing, CNC precision machining and laser cutting, taking plastic profiles and blanks as raw materials. This flexible processing method is suitable for small-batch customization and personalized orders, and completely retains the core advantages of Vespel SP-211 such as extreme temperature resistance, structural stability and insulation performance.
It is worth noting that Vespel SP-211 material has high hardness and abrasiveness, which will cause tool wear during processing. Professional diamond or carbide tools are required, and strict cooling and feeding speed control are needed to avoid local overheating, material micro-cracks and performance attenuation, ensuring high-precision and high-quality finished parts.

Core Material Performance Characteristics
Extreme Temperature Resistance (High & Low Temperature)
Vespel SP-211 features outstanding dual high and low temperature resistance. Its long-term continuous operating temperature reaches 300°C, and the decomposition temperature is up to 450°C. In low-temperature environments, it remains stable without brittleness and cracking even at an ultra-low temperature of -269°C (liquid nitrogen environment). It can operate reliably for a long time in the air at -240°C to 288°C, maintaining stable mechanical structural performance in extreme temperature difference scenarios.
Ultra-Low Friction & Self-Lubricating Performance
Benefiting from 10% PTFE and 15% graphite composite filling, Vespel SP-211 has an extremely low friction coefficient of 0.05–0.15, which can even drop below 0.05 under specific working conditions. Graphite effectively enhances wear resistance, while PTFE provides excellent self-lubricating properties. The material maintains low wear and smooth friction state even at 300°C high temperature, greatly reducing equipment operation friction loss. It is worth noting that tiny particle abrasion may occur during long-term operation, so it is not suitable for ultra-high precision vacuum dust-free equipment.
Stable Mechanical Properties
The material has a stable elastic modulus of 3–4 GPa, and the fiber-structured Vespel SP-211 can reach a modulus of 200 GPa. Although PTFE filling slightly increases the thermal expansion coefficient and reduces partial tensile strength, the overall mechanical rigidity and structural stability are excellent. It is not easy to deform or warp under high temperature and long-term stress, maintaining consistent dimensional accuracy.
Excellent Flame Retardant & Radiation Resistance
Vespel SP-211 has superior flame retardant performance, featuring self-extinguishing properties and low smoke generation, meeting high-standard fire safety requirements for industrial equipment. In addition, it has strong high-temperature radiation resistance, and its electrical and mechanical properties remain stable after high-dose radiation irradiation, suitable for nuclear energy and high-radiation industrial scenarios.
Superior Chemical & Solvent Resistance
The material exhibits excellent tolerance to conventional organic solvents, acids and alkalis, resisting chemical corrosion and medium erosion in complex industrial environments. It supports repeated high-temperature sterilization, is non-toxic and safe, and can be applied in medical equipment and food-grade tableware auxiliary parts.
Professional Machining Guidance
Vespel SP-211 filled polyimide material has high hardness and strong abrasiveness, which easily causes tool wear during processing. To ensure processing accuracy and part quality, it is recommended to use high-hardness diamond or carbide cutting tools. Strict real-time cooling and reasonable tool feeding speed control are required during machining to avoid local overheating of the material, prevent micro-cracks and structural performance attenuation, and ensure the dimensional stability and structural integrity of finished precision parts.
