PEEK Raw Material Grade:
PEEK Impeller Application Scenario:
Adopting PEEK450CA30, the impeller of the electric vacuum cleaner is manufactured by injection molding process, replacing the original metal impeller formed by casting mold, and the rotating speed is up to 110,000 rpm when the power is turned on, and when the peek blade rotates, the air is pushed to the exhaust port and continuously discharged. (DyasonVacuum cleaner)
Advantages of using PEEK Impeller:
- Balancing properties are greatly improved
- High strength (260 MPa)
- Low 50% noise level
- High rotational speed (>100,000 rpm)

- Fatigue resistance
- Low creep deformation
- Chemical resistant
- Up to 40% weight
- Quieter and smoother operation of the vacuum cleaner
- Up to 2% energy efficiency

Civilian UAV propeller blade is an important part with high technology content, complex manufacturing processes, and harsh material performance requirements, and the choice of propeller material affects whether the civil UAV flight mission can be completed and whether the flight is stable and long-lasting.
PEEK material has good comprehensive performance, and its use in UAV blades is characterized by:
- Weight reduction and noise reduction: the use of PEEK and short fiber composite materials can reduce weight while maintaining the excellent performance of the fuselage material, improve the strength of the paddle itself, better dynamic balance, and more significant effect of mute noise reduction.
- High strength: compared with traditional metal materials, it has the characteristics of high strength and stiffness. If it encounters the impact of other foreign objects during the flight, the special material of the paddle blade will make it not easy to be damaged, and it can maintain the normal flight of a civil UAV.
- Good flight stability: PEEK and its composite materials have a small coefficient of thermal expansion, strong fatigue resistance, and vibration resistance, which can be used normally in harsh environments, and the paddles are not easy to deform due to the external environment and have a long service life.
