What Molecular Products Group does

Molecular Products Group plc is a specialty manufacturer of life-critical devices for the treatment of breathable gases, headquartered in Louisville, Colorado with primary UK operations in Harlow, Essex. Founded in 1924 as Medical Practitioners United Drug Co and rebranded in 1988, the company sells four integrated technology platforms: CO2 absorbents (Sofnolime and Sodasorb soda lime brands, including pre-filled cartridges), solid oxygen generation systems (MPOG, eMPOG, EO2-30, CAN-33, ROG), activated carbon filtration media (Chemsorb MilSpec and MultiGard CBRN grades), and specialty catalysts and molecular sieves (Sofnocat, Ionex, Moleculite, Sofnofil, SofnoSiv). These products serve six end markets - defense (submarines, CBRN protection), healthcare (anesthesia CO2 absorption), diving (rebreathers, hyperbaric chambers), mining (refuge chambers), industrial safety (respirators, collective protection), and gas processing (LPG polishing, emission control, hydrogen liquefaction).

The company operates three manufacturing facilities (Louisville CO, Harlow UK, Connellsville PA), five direct sales offices (USA, UK, China, India), six regional logistics hubs, and an authorized distributor network covering more than 50 countries, with end products exported to over 80 countries. Revenue derives from one-time product sales of regulated consumables, with the company supplying over 2.8 million pre-filled CO2 absorber cartridges annually and serving embedded OEM customers such as GE Healthcare and Midmark alongside defense customers including the UK MoD, US Navy, NATO navies, NASA, and Naval Group. Pricing is not publicly disclosed and is set via direct enterprise sales or distributor agreements. The business is privately held, currently owned by Filtration Group (a Madison Industries affiliate) following a 2021 acquisition, and was previously held by Arlington Capital Partners from 2016 and earlier by the founding McKernan family and Business Growth Fund.

The company holds ISO 9001 and ISO 13485 certifications and has cleared FDA, CE, NIOSH, and MSHA approvals on its medical and safety product lines. Recent strategic activity has centered on capacity expansion (Pure O2 Center in Harlow in 2020; new soda lime capacity in Louisville in 2020), portfolio acquisitions (Sodasorb from Henkel in 2018, O.C. Lugo in 2019), US DoD DPA Title III funding (2016 and 2018) for MilSpec activated carbon capacity, and new product introductions including the FDA 510(k)-cleared ROG personal oxygen generator and the Ionex OP Catalyst for liquid hydrogen liquefaction.
