Thermoid named Logan County Chamber Business of the Month


Founded in 1883, Thermoid manufactures one of the broadest lines of industrial rubber products available anywhere in the world. The products manufactured by the company are used in dozens of industries including air, automotive, aviation, bulk transfer, chemicals, marine, water and welding. From industrial pipes and pipelines to conveyor belts, Thermoid’s engineering expertise and customer focus has enabled it to provide products for even the most challenging environments through air, soil, sub- sailor and even space.

Thermoid was acquired by HK Porter Company, Inc. in 1958 and just 10 years later the company established its pipe factory in Bellefontaine. In 1987, HK Porter placed all of its rubber products factories into a wholly owned subsidiary named HBD Industries. Logan County was chosen from two final site options for the company.

The Bellefontaine manufacturing plant currently employs nearly 200 people, including generations of families, and produces industrial rubber hoses. Thermoid is a leader in the development of innovative hose designs and manufacturing production techniques, including its own Concure® continuous manufacturing process, which was invented, developed and patented by Thermoid to help produce the best hoses. The Concure® process ensures dimensional stability, provides a flexible, contamination-free, smooth hose in long, unbroken lengths. Thermoid further uses Thermocure, its patented manufacturing process, to provide a consistent inside and outside diameter, to facilitate pipe coupling, and to help its smooth cover provide increased durability when sliding on rough surfaces.

Based in Dublin, the nine companies under HBD together employ 900 people. Locations can be found across the United States including North Carolina, New York, California, Kansas, Tennessee, and Georgia.

When not at work, Thermoid employees love to give back to the Logan County community. The company has been involved in a variety of community activities, including fundraising for United Way of Logan County and volunteering for Habitat for Humanity and the Second Harvest Food Bank. Company employees organize an annual holiday toy drive to benefit local families. “Thermoid prides itself on being an active and involved member of the community. The Logan County Chamber was an integral part of our participation, ”says Lisa Guyett, Head of Human Resources.
