PEEK (polyetheretherketone) material has a high continuous use temperature (approximately 260 degrees), high stiffness and hardness, as well as some high tensile strength and fatigue resistance. In addition, it has excellent heat resistance, deformation resistance, and chemical stability. The material has good dielectric properties and can resist energy ray irradiation until the temperature reaches 260 degrees. PEEK has excellent comprehensive properties, good mechanical properties, high temperature resistance, and superior chemical resistance, making it a more versatile plastic.
Characteristics: high mechanical strength, rigidity and hardness, high temperature resistance, chemical resistance and hydrolysis resistance, wear resistance and friction performance, etc. PEEK is widely used in industries such as aerospace, medical, machinery, automotive, and food processing.
PVDF (polyvinylidene fluoride) has higher stiffness and pressure bearing capacity than similar polytetrafluoroethylene, but its smoothness and electrical insulation are slightly inferior. It has high strength and toughness under low temperature conditions and can self extinguish. Its working temperature is between -30 degrees and 150 degrees. PVDF can maintain stability against chlorides, bromides, and energy rays.
Characteristics: High allowable working temperature in large air (can work continuously at 150 degrees), excellent resistance to chemical corrosion and hydrolysis, outstanding resistance to ultraviolet radiation and weather. High mechanical strength, good rigidity, and good creep resistance. Good sliding and wear resistance. Inherent low flammability and good electrical insulation performance.
However, in terms of temperature and mechanical properties, PEEK is superior to PVDF. Nanjing Yuwei has been committed to the field of special plastics for many years, and can carry out various molding processes such as extrusion molding, injection molding, compression molding, and machining molding. Develop and manufacture injection and molding molds according to customer drawings and/or sample requirements, and customize PEEK parts and finished products with various specifications and wide applications.
