What Mercury Plastics does

Mercury Plastics LLC is a privately held custom thermoplastic manufacturer founded in 1965 and headquartered in Middlefield, Ohio, where it operates three co-located manufacturing plants. Since 2017 the company has been a wholly owned subsidiary of Masco Corporation (NYSE: MAS), a Fortune 500 building-products conglomerate, and operates with continued management autonomy. Mercury is vertically integrated across five in-house process capabilities — custom profile and tubing extrusion, proprietary Air-Core® blow molding, forming and fabrication, injection overmolding, and industrial electron beam (e-beam) processing for polymer crosslinking and bioburden reduction — serving OEM customers from concept through production in markets including plumbing, water dispensing and filtration, wire and cable, and battery energy storage systems, with secondary exposure to appliance, automotive, building products, electrical, marine, medical, and offshore oil and gas.

The company's principal differentiator is its ownership of two of the largest e-beam accelerators in North America — a 5 MeV unit and, as of October 2025, a newly installed $15 million 10 MeV IBA Rhodotron accelerator — which together enable high-throughput, chemical-additive-free PEX-c crosslinking and advanced polymer modification. Branded product lines such as Merflex® PEX OT® tubing and Click Connex® connection systems, combined with deep regulatory certifications (ISO 9001:2015, NSF 14 and 61, ASTM F876/F877, CSA B137.5, PPI TR-4, ASME A112.18.6, DIN 4726, PFAS-free), are integrated into customer specifications and bills of materials.

Mercury generates revenue through two streams: (1) custom thermoplastic component manufacturing (extruded profiles, tubing, blow-molded parts, formed and overmolded assemblies) sold B2B via direct enterprise field sales with collaborative engineering engagement across the United States, Canada, and Mexico; and (2) fee-based electron beam processing services for polymer modification and bioburden reduction offered to wire and cable, industrial, and laboratory customers. Pricing is quote-based and not publicly disclosed; lead times of 7–10 working days are quoted against an industry norm of 3–4 weeks.
