Dover Chemical Corp

What Dover Chemical Corp does

Dover Chemical Corporation is a U.S. specialty chemicals manufacturer and a wholly-owned subsidiary of ICC Industries Inc., headquartered in Dover, Ohio with a second manufacturing facility in Hammond, Indiana. The company produces a diversified portfolio of chemical additives including alkylphenols, liquid and solid chlorinated alkanes, polymer additives (Doverphos® phosphite stabilizers, Dovernox® hindered phenol antioxidants), flame retardants, and additives for water-based and oil-based metalworking fluids (Doverlube®, MAYFREE®, DOVERLUBE 31700) and drilling mud applications. Its technology is anchored by proprietary formulations — most notably Doverphos® LGP-12, a polymeric phosphite antioxidant stabilizer containing no alkylphenol components or SVHCs — supported by dual U.S. FDA and European Commission food-contact authorizations that constitute a regulatory barrier in food-packaging markets.

The company sells directly to industrial customers in the U.S. and Canada from its Ohio headquarters and reaches international markets through ICC Trading Inc., the global trading arm of its parent conglomerate. Revenue is generated through B2B unit pricing with quote-based contracts negotiated by regional sales managers and cost-pass-through price increases tied to raw material, transportation, and manufacturing cost movements. Customer end-markets span six primary segments: drilling mud additives, metalworking fluids, paints/coatings/adhesives, plastics, rubber, and textiles. Dover Chemical holds ISO 9001:2015 certification, is a member of the American Chemistry Council with Responsible Care program participation, and earned an EcoVadis Bronze Medal in 2024. Its product cadence has remained active through 2026, with platform extensions such as DoverCycle™ (recycled polyolefins, 2025) and EcoGuard LCCP positioning the company around sustainability and regulatory tailwinds.

Core offering

Dover Chemical Corporation manufactures and sells specialty chemical additives for industrial applications. Its core portfolio includes alkylphenols, chlorinated alkanes (liquid and solid), polymer additives (phosphite stabilizers and hindered phenol antioxidants), flame retardants, and additives for water-based and oil-based metalworking fluids and drilling fluids. Products are sold under proprietary brands such as Doverphos®, Dovernox®, Paroil®, Doversperse, Doverlube®, DoverClear™, and MAYFREE to industrial customers in plastics, rubber, textiles, paints/coatings/adhesives, metalworking, and oilfield drilling.

Product overview

Dover Chemical Corporation is a leading producer of specialty chemical additives serving diverse industrial markets. The company operates as a single-company specialty chemicals manufacturer with multiple complementary product lines rather than a platform-plus-modules architecture. Core product lines include polymer additives (Dovernox® hindered phenol antioxidants and Doverphos® phosphite stabilizers including Doverphos® LGP-12 and DoverCycle™), chlorinated alkanes (liquid Paroil® and solid forms), metalworking fluid additives (Doverlube® line including MAYFREE 2033 and DOVERLUBE 31700), drilling mud additives, alkylphenols, and PIBSA dispersants. These products serve markets including plastics, rubber, textiles, paints/coatings/adhesives, metalworking, and oilfield drilling. The company emphasizes regulatory compliance with FDA and EU food-contact authorizations for its Doverphos® LGP-12 technology, and sustainability through products like DoverCycle™ for recycled polyolefins and EcoGuard LCCP alternatives.
