Electronics
Sorbothane is widely used to isolate delicate electronics - printed circuit boards, LCD’s disk drives and other devices.
Applications include rocket launchers and wind turbines.
Shock Absorbers
Sorbothane is designed to absorb energy. it does not compress and it returns to its natural shape time and time again after contraction. dilation and distortion. A small amount can deliver an improvement.
Acoustics
The Sorbothane hemispheres are used throughout the world in the highest quality audio equipment. In addition we can offer custom designed solutions to improve your system.
Gaskets
Sorbothane is a popular material for gaskets because of its chemical resistance, its ability to conform to irregular surfaces. its low creep and its reusability. Its natural tackiness makes it easy to install. Gaskets can be made from sheet material or produced to order.
Procedure for selecting a vibration isolator.
- Determine the load (weight) of the unit that requires isolation. Divide the weight of the system by the number of isolators to be used to establish the load per isolator.
- Determine the lowest critical frequency (excitation frequency) of the system e.g. the rpm of the motor. the rate at which a cylinder strokes or the output speed of a reducer. Divide minute-based information to by 60 to convert to hertz (cycles per second).
- Select an appropriate isolator by using the information charts shown on the website. Generally an appropriate isolator will create a system natural frequency at least one third lower than the excitation frequency. For instance, if the source of the vibration is an 1800 RPM motor. then the excitation frequency is 1800/60 = 30 hertz. The resultant damped natural frequency should be 20 hertz or less.
- Select the isolator that meets the technical and physical requirement s of your system. In addition to a part number. you must also specify the durometer of the Sorbothane part required to get the specified load rating. Do not oversize isolators. Oversized isolators raise the natural frequency and reduce the effectiveness. Sorbothane will be supplied as black coloured material although for large volume orders we can offer a range of colours.
- Remember: Sorbothane works best in compression and therefore if you have a tension application then bushings are the best option.
