Certified Thermoplastics Co., Inc.
Certified Thermoplastics was founded in 1978 by George Duncan, a chemical engineer and Air Force pilot who previously worked for Rogers Corporation, and Bard Parker. His son Robert took over in 2004 and most recently, in 2018, the company was acquired by Ducommun Incorporated. Ducommun (NYSE:DCO) was founded in 1849 and is the oldest continuously operating company in California. Ducommun has been a supplier to the aviation industry since planes first began flying, and Certified is proud to be a part of this great company.
Originally a supplier of custom plastic extruded profiles to the aviation & aerospace industries, including civilian, military and defense contractors, Certified now supplies extrusions and extruded assemblies to a wide variety of industrial customers. Some of the applications our extrusions are used in include LED lighting lenses and bases, medical applications such as surgical tray dividers and bumpers (extruded from chemically resistant resins reusable after autoclave sterilization), energy exploration including solar applications and oil extraction, instrumentation, communications, and parts for industrial machines such as extruded spindles for lathes or platens for wide format ink jet printers.
