What Is The Difference Between PVDF And PEEK Screws?

November 16, 2023

What is the difference between PVDF and PEEK screws?


PEEK (polyetheretherketone) screw materials have extremely high continuous use temperatures (about 260 degrees), and also have high bending stiffness and strength, as well as unique high compressive strength and fatigue resistance. In addition, it has outstanding high temperature resistance, non-deformation performance and organic chemical stability. When the temperature reaches 260 degrees, the material has good electrical polarization properties and can resist direct kinetic X-ray radiation. PEEK has comprehensive properties, good mechanical performance, high temperature resistance, and excellent solvent resistance, making it a practical high-grade plastic.



Features: high impact toughness, stiffness and strength, high temperature resistance, acid resistance and hydrolysis resistance, wear resistance and friction performance, etc. PEEK is widely used in aerospace, diagnosis and treatment, machinery and equipment, vehicles and food manufacturing and other fields.

PVDF (polyylidene fluorobutadiene) has higher bending stiffness and pressure resistance than similar PTFE, but is less smooth and has less electrical insulation properties. It has high toughness and high wear resistance under ultra-low temperature conditions. Its working temperature ranges from -30 degrees to 150 degrees. PVDF can withstand fluoride, bromide and their kinetic energy X-rays for a long time.



Features: high air working temperature (can work continuously at 150 degrees), excellent resistance to chemical corrosion and hydrolysis, outstanding UV resistance and weather resistance. It has high impact toughness, good stiffness and good stress relaxation resistance. Excellent rolling properties and wear resistance. Original low flammability and good insulation performance.



However, in terms of use temperature and mechanical performance, PEEK is better than PVDF.
