Electrical Insulation Materials

Electrical insulation materials have played a pivotal role in industrial development and global electrification, dating back to the introduction of vulcanized pressboards in the mid- to late 1800s and synthetic resins in the early 1900s.

From simple washers and spacers to fuse tubes and high-voltage standoff insulators, the availability of high-quality thermoset laminates, pultruded shapes, and machined, punched, or molded parts has enabled a wide range of critical applications across numerous industries.

These materials are more than components—they are foundational to the performance, safety, and efficiency of countless systems, representing a significant and ongoing contribution to the global economy.
