Standoff Insulators

March 30, 2023

Mar-Bal, Inc. (Mar-Bal: Chagrin Falls, OH), previously named for two consecutive years by Inc. magazine as one of America’s fastest growing privately held companies, is the largest manufacturer of BMC molded Standoff Insulators in North America. The ISO 9001:2015 Registered Company manufactures the industry’s two leading brands−Glastic and Mar-Bal. The UL Listed Standoff Insulators are molded from a flame retardant and track resistant glass reinforced thermoset polyester molding compound.

Notably, they combine high mechanical strength with high arc resistance and dielectric properties at elevated temperatures and humidity. These shatter resistant insulators meet the most exacting standards for a variety of applications. For nearly a century Mar-Bal’s portfolio, which includes the “Glastic” line, has brought the combined standoff insulator experience and innovation to the marketplace−from their UL certificates, to product and brand leadership, as well as reliability and dependability.

In 2012, Mar-Bal acquired Glastic’s line of standoff insulators to officially combine two industry leaders under the same roof, and provide the company with a strong complimentary brand to their existing line. Today, Mar-Bal continues to evolve their insulator line and production capabilities with a focus on markets including BEV, EVT, and renewable energy such as Wind and Solar, amongst others
