Comparative Data Sheets

In today’s technology-driven marketplace, it is important to understand the material to be specified and used in electrical and electronic equipment applications. The cost of failure is incredibly high regarding safety, the cost of downtime, productivity, and direct cost.

The evaluation and testing of non-metallic materials must start with a solid understanding of a material’s construction and properties. When it comes to electrical insulation, one of the biggest challenges facing engineering teams today is specifying the proper material for their application. These comparative graphs are intended to be engineering resources to help compare like materials and determine which one best suits the application.

If you would like to review your application and discuss potential material candidates, our trained material specialists are standing by, ready to assist you and your engineering teams.
