Sumitomo Bakelite Kenton Plant to Close Starting 2027

Kenton Plant Production Phaseout

Sumitomo Bakelite Kenton Plant production will be phased out product by product beginning in September 2027, according to an announcement made September 28. The Kenton Plant, operated by consolidated subsidiary Durez Corporation in Ohio, United States, manufactures phenolic resins and other products. Once the phaseout begins, affected products will either be discontinued or transferred to other production sites. The announcement does not provide a single fixed closure date, indicating that the timing will depend partly on the company’s existing contractual supply commitments.

Reasons Behind the Plant Closure

Sumitomo Bakelite Co Ltd said the decision followed a review of the Kenton Plant’s aging facilities, the capital investments that would be required in the future, and the company’s broader production structure in North America. These factors led the company to determine that changes to the plant’s production arrangement were necessary. Rather than ending all affected production at one time, the company plans a product-by-product phaseout beginning in September 2027, allowing the final closure timing to account for existing contractual supply obligations.

Automotive Applications of Phenolic Resins

The products associated with Sumitomo Bakelite’s phenolic resin portfolio have applications across several automotive components and materials. According to the company, phenolic resins are used in materials for brake pads, clutch friction materials, and tires. Fiber-reinforced phenolic resin composites are also used in engine-related components, electrical components, and disc brake components. These applications demonstrate the relevance of phenolic resin materials to multiple vehicle systems, although the September 28 announcement did not identify which specific applications are served by products manufactured at the Kenton Plant.

Production Transfers and Closure Timing

The planned phaseout means production of affected Kenton Plant products will follow one of two paths: discontinuation or transfer to other sites. The company has not stated which individual products will move to alternative facilities or which will be discontinued. The final closure date will also be determined later, with fulfillment of existing contractual supply obligations identified as one factor in that decision. As a result, the September 2027 start of production phaseouts establishes the beginning of the transition rather than a confirmed final shutdown date.

Industry Impact & Outlook

The Kenton Plant decision could affect the supply structure for phenolic resin products used in several automotive applications, particularly as production is phased out and selected products are potentially transferred elsewhere. For customers relying on affected materials, the practical implications will depend on which products are discontinued, which are relocated, and how contractual supply obligations are fulfilled. The broader significance for North American manufacturing will become clearer as the company identifies product-level transition plans and establishes the final closure timing, while the impact on individual automotive components cannot be determined from the September 28 announcement alone.
