Siloxane Monitoring for Contact Failure of Electrical Parts

Contributing to Cause Investigation of Electrical Parts’ Contact Failure to Improve Production Yields

Siloxanes have a number of excellent properties such as high lubricity, water repellency, and electrical insulation. Taking advantage of this, it is used in silicone rubber, oil, adhesives which are used inside electrical and mechanical products, personal care products such as shampoos and conditioners, and various other medical supplies and daily necessities.

Although siloxane has excellent properties, it can cause problems.

Contact parts such as relays and motors, used in automobiles, electrical and mechanical products, may cause contact failure if siloxane, volatilized from the silicone materials, adheres to the surface of parts.
