Excellent mechanical performance
PEEK has high strength and stiffness, its stretching strength can reach about 90-100MPa, and the curved strength is as high as 170MPa. This enables Peek screws to withstand large tensile and pressure, and performs well in some application scenarios with higher mechanical performance. For example, in some components around the car engine, the Peek screws can still maintain good tight performance in the case of high temperature and vibration.
It also has good toughness and is not easy to break when it is impacted. Compared with the screws made of some crispy materials, the impact resistance of the Peek screw is better, and the reliability in a complex and changeable environment is higher.
High temperature resistance is prominent
PEEK screws can be used for a long time at a higher temperature. The glass transformation temperature is about 143 ° C, and the melting point is as high as 334 ° C. Under high temperature environments, such as near the air dissipation area near the aerospace industry or the heat dissipation area of electronic equipment, the Peek screws can maintain stable performance and will not soften and deform as some ordinary plastic screws. For example, in some auxiliary devices of aviation engines, the Peek screws can withstand high temperatures of 200-1250 ° C to ensure the safe and reliable operation of the equipment.
Good chemical stability
It has excellent tolerance for most chemicals, including acid, alkali, organic solvents, etc. In the fields of chemical equipment and pharmaceutical equipment, Peek screws can resist the corrosion of various chemical reagents. For example, in the connection of the reactor component of the pharmaceutical factory, the Peek screw will not be corroded by the pharmaceutical composition or the chemical reagent for cleaning, thereby extending the service life of the equipment and ensuring the quality and safety of the product.
Over abrasion resistance and self -lubrication
PEEK screws have high surface hardness and have good wear resistance. In some devices that need to be disassembled and installed frequently, the Peek screws can reduce wear and maintain good thread accuracy. At the same time, it also has a certain self -lubrication. During the friction process, the friction force can be reduced, making the screw tightering and loose operation smoother. For example, in the assembly of some precision instruments, the Peek screws can be easily operated without additional lubrication, and reduce the wear of the internal precision components inside the instrument.
Good electrical insulation performance
The Peek screw is an excellent electrical insulation. Its dielectric constant is between 3.2 -3.5 and the volume resistance rate is as high as 10¹⁵ -10 ω ・ cm. In electronic electrical equipment, the Peek screw can effectively prevent current leakage and short -circuit. For example, in the installation of the circuit board, PEEK screws can be safely used to fix electronic components to avoid damaging electronic components due to screw conductivity.
