Electrical Properties

Rubber materials are commonly used as insulators in a variety of applications. This is critical to both the protection of the components themselves and the operators or personnel handling the end product.

The material needs to have high resistance as well as the appropriate durability characteristics to be used in the operating environment.

Our experts at Smithers Rapra commonly tests materials for their resistivity and conductivity in addition to a wide variety of material performance criteria.  Resistivity and conductivity testing (also referred to as dielectric strength, volume resistivity, and surface resistance) can also indirectly measure characteristics such as moisture content, degree of cure, or material deterioration.
