It is an ideal damping material and has damping effect on vibration.
It has great linear flexibility, can be almost stretched to fracture without losing its elasticity, and can withstand alternating stress without fatigue. Like water, it is almost incompressible, and only produces elastic deformation after compression, but its volume remains unchanged.
When the temperature is below - 30 ℃, the elasticity of the shock absorber will be significantly reduced, and the shock absorber should not work in severe cold conditions; At the same time, it is not resistant to high temperature, and its working temperature should not exceed 75-80 ℃.
The compressive strength of is much greater than the tensile strength. The tensile length of is generally about 6 times larger than the compression distance. The natural vibration frequency is not the same under tension or compression.
There is an "elastic aftereffect" phenomenon, that is, the deformation increases rapidly within about 20 minutes after compression (about 25%, that is, the deformation ratio is 1.25); After that, the deformation was very slow, and it increased to about 50% after about 15 days.
These physical characteristics of the shock absorber will affect the design, selection and application of the shock absorber. Users should know more about and pay attention to the flying shock absorber when using it.
