Vespel Parts Vespel Nuts

Characteristics of vespel nuts include heat resistance, abrasion resistance, creep performance, deformation to load, and chemical resistance. 

 

Heat Resistance: Vespel materials are able to maintain good performance in high temperature environments, with resistance to temperatures of up to 288°C for continuous use and up to 480°C for short periods of time.

 

Abrasion resistance: Vespel's non-lubricated limit PV value is more than 10 times that of general engineering plastics, and it has strong resistance to impact abrasion and shaking abrasion.

 

Creep performance: In the creep test at 260°C and 186kg/cm2, there is only 0.6% deformation in 1000 hours, showing good stability.

 

Deformation performance to load: the deformation under 50°C, 140KG/2 condition is 1/70 of PTFE, 1/10 of nylon, showing its excellent resistance to load.

 

Chemical resistance: Vespel is resistant to grease, oil, and solvents, and is not easily burned like metal.

 

In terms of usage, Vespel nuts are widely used in occasions that need to withstand extreme conditions, such as in the Apollo Moon Landing Program for bearings, anti-loosening nuts, and other parts of the lunar landing vehicle to endure the extreme environment of high and low temperatures, radiation, and other extreme conditions on the moon. In addition, Vespel materials are also used to manufacture edge rings, which come in a variety of materials and sizes and are suitable for use in a wide range of instruments and applications, including GC/MS, demonstrating their importance in high-tech and industrial applications.
