The answer is yes—and in more ways than one. Rubber is an excellent isolator. It is used to isolate vibration, shock, and noise in mechanical systems, and also acts as an electrical insulator due to its high resistance to electric current. Is rubber an isolator In my factory visits, I’ve seen rubber pads under machines, bushings in cars, and even rubber gloves in electrical work—all using rubber’s natural isolating properties to solve different problems. How does rubber isolate vibration and shock? Most commonly, rubber is known for its ability to isolate mechanical vibration and shock. Rubber’s elasticity and flexibility allow it to absorb and dissipate energy, reducing the transmission of vibration and shock between connected parts.

They are simple, affordable, and effective. Is rubber also an electrical insulator? Yes! Another key property of rubber is its ability to resist the flow of electricity. Rubber is a strong electrical insulator.6 It has very high resistivity, so it blocks the passage of electric current.
