For over six decades, Electrolock has been engineering the invisible solutions that power the world’s most critical applications. What began as a small Ohio business in 1957 has evolved into a global leader in custom electrical insulation, serving industries from power generation to electric vehicles with materials that make all the difference where you can’t see them.

In 1957, Electrolock began in Ohio Joe Williams Jr. joined the company in 1959, establishing the foundation for decades of growth. The company relocated to Chagrin Falls, Ohio, where it became a successful manufacturer’s representative with light distribution capability.
Recognizing the growing demand for specialized electrical insulation, Electrolock built its first converting facility in 1969 to support distribution of various electrical insulation materials to the power equipment market. This move marked the company’s transition from distribution to manufacturing — a decision that would define its future.
The late 1970s brought significant technological progress. In 1977, Electrolock installed its first computer system alongside new converting equipment, modernizing operations and capabilities. A technical sales force was added, bringing engineering expertise directly to customers’ applications.
By 1981, the company had built a materials laboratory at the Ohio facility, establishing its commitment to testing and product development. This investment in R&D capabilities positioned Electrolock as more than a manufacturer — it became a solutions partner.
In 1984, Electrolock opened its South Carolina facility to better serve southern states and add operational capabilities not available at the Ohio plant. This expansion enabled the company to extend sales throughout the United States and Europe while adding strategic insulation partners.
Today, Electrolock serves markets worldwide with key partners across electrical and thermal insulation product ranges.
Our technical sales force and engineering departments continue to drive innovation and growth, incorporating state-of-the-art equipment and processes to meet demanding customer requirements with shorter life cycles, tighter tolerances, and increasingly critical quality metrics.
Our mission is to create bespoke solutions, along with our standard product offerings, to service our customers’ most demanding requests. With products ranging from mica tapes, process films, and cut-through insulation to CNC’d rotor turn insulation, battery sleeves, and thermal barriers, we have a solution for YOU.
We make it a point to understand the design, process, and cost considerations of your insulation requirements. Our engineers, technical specialists, and extensive network of resources bring the experience and know-how to your applications. We work with you to define the problem, then design, manufacture, and test the solution.
We stand behind our solutions and recommendations, even when difficult conversations are required. Our commitment to integrity means providing honest assessments and delivering exactly what we promise.
Every decision we make considers how it serves our customers, partners, and communities. Service isn’t just what we do — it’s who we are.
Our success comes from collaboration — between our engineering teams, with our customers, and across our global partner network. Together, we solve challenges that individual efforts cannot.
Electrolock maintains strict quality control policies at each step of the manufacturing process, beginning with incoming material inspection and ending with statistical evidence that each product meets specified customer conditions. Our commitment to quality guarantees that the end product meets your most demanding performance requirements.
We encourage creative problem-solving and embrace new approaches to complex insulation challenges. Innovation drives our evolution from traditional electrical applications to cutting-edge battery and thermal solutions.
What sets Electrolock apart isn’t just our 65+ years of experience — it’s our commitment to understanding that what you can’t see makes all the difference. From mica tapes that prevent electrical failures to thermal barriers that stop battery fires, our solutions protect the critical systems that power modern life.
