Mercury Plastics

Mercury Plastics refers to several active U.S.-based plastics manufacturing companies specializing in custom thermoplastic solutions for diverse industries such as appliance, automotive, construction, plumbing, marine, liquid dispensing—and to a lesser extent—medical devices and healthcare packaging. The main entity "Mercury Plastics LLC" operates from Middlefield, Ohio with three facilities focused on extrusion, injection overmolding, cross-linking via electron beam processing (including PFAS-free processes), rapid prototyping with 3D printing capabilities and quality testing labs. In December 2017 it was acquired by Masco Corporation. Other similarly named firms include "Mercury Plastics Inc."—a major extruder/printer/converter of polyethylene films serving North America—and its Maryland division ("Mercury Plastics MD"), plus a California-based operation under Sigma Plastics Group.
