Abstract
A selected region of a conductive elastomer is made relatively nonconductive by subjecting said region to ultrasonic vibration and pressure.
Claims6
A method of making a selected region of a metal particle-filled elastomer relatively nonconductive comprising the steps of:
- subjecting said selected region to ultrasonic vibration and pressure;
- and
- maintaining said region subjected to said ultrasonic vibration and pressure for a sufficient time until the electrical conductivity of said region is substantially reduced.
