Dover Chemical Corporation is a leading producer of alkylphenols, chlorinated alkanes, polymer additives, liquid and solid antioxidants (including organophosphites), flame retardants, additives for water-based and oil-based metalworking fluids and drilling fluid additives.

Dover Chemical has grown into a leading producer of organophosphites by continuing to identify and meet market needs of product consistency, high purity, and fast-response time. Our ability to continually develop innovative products and our commitment to working closely with customers have contributed to our success with these products. Dover Chemical offers a line of solid antioxidants for use in a wide range of polymers to further broaden our product range. 

Doverphos® LGP is unique in that it contains no alkylphenols. Additionally, it offers excellent compatibility in thermoplastic resins, resulting in reduced additive migration and exposure, especially for indirect food-contact applications.

Our umbrella of products is designed to meet stringent protocols, including many with FDA approval, while delivering thermal and hydrolytic stability and excellent color. DoverPhos® LGP phosphite stabilizers provide compatibility in thermoplastic resins and rubber, resulting in reduced additive migration and exposure.

Our manufacturing facilities are located in Dover, OH and Hammond, IN. Our Dover location is along Interstate 77 in east central Ohio, providing easy access for shipping. The Hammond location is just 17 miles south of Chicago, along the Interstates 80-94 corridor. 

Dover Chemical is proud to have earned ISO 9001:2008 certification in recognition of our ongoing commitment to uncompromising quality. We join other members and partners of the American Chemistry Council in our dedication to the principles of Responsible Care, including product stewardship, community awareness, emergency response, pollution prevention, process safety, distribution, and employee health & safety.
