What Composition Materials does

Composition Materials Co., Inc. is a privately held industrial manufacturer founded in 1923 and headquartered at 249 Pepes Farm Road, Milford, Connecticut. The company produces and supplies abrasives, blast media, fillers, and cosmetic-grade ingredients built around two raw-material pillars: recycled thermoset plastics (marketed under the PLASTI-GRIT® trademark and available in five grades — Type I Polyester, Type II Urea, Type III Melamine, Type V Acrylic, and Type VI Clear-Cut®) and naturally occurring agricultural by-products (walnut shell, apricot shell, pecan shell, almond shell, corn cob, rice hulls, wood flours, and tagua). Several PLASTI-GRIT® grades are Mil-Spec approved (MIL-P-85891A) for paint stripping and coatings removal; additional offerings include mineral abrasives (aluminum oxide, steel shot, steel grit, glass beads, silicon carbide), cryogenic and ambient deflashing media (polycarbonate, nylon, polystyrene), and non-skid aggregates.

The company's technology stack is conventional mechanical — milling, sifting, and grading of recycled and agricultural feedstocks — combined with proprietary formulation know-how spanning a century of operation. Manufacturing operations have been solar-powered since 2014. Composition Materials sells direct to industrial end-users via phone (800-262-7763), website inquiry, and global shipping, with products packaged in 50 lb boxes, 275 lb drums, and 2000 lb super-sacks. Pricing is quote-based across all SKUs, with no public price list disclosed.

End markets are diversified across aerospace and aviation, automotive restoration, paint and coatings, rubber/plastics/electronics manufacturing, construction and restoration, and cosmetics/personal care — the last vertically benefiting from the 2015 federal ban on plastic microbeads, which positioned the company as a natural-ingredient alternative. The company holds three registered trademarks (PLASTI-GRIT®, Clear-Cut®, CM Mask®), a BBB accreditation, and Mil-Spec approval, but operates with 1-10 employees and no disclosed venture capital, private equity backing, or parent company.
