Mo-Sci was founded by Dr. Delbert Day in 1985 to develop and supply specialty glass and ceramic products for specific market applications.
Mo-Sci supplies glass microspheres, fibres, and powders to the medical device industry.
It also provides sealing glass and test services for the aerospace, automotive, and electronics industries.
The company was led by Ted Day, Dr Delbert’s son, up until his passing in September 2020.
ETS was founded in 2012 to develop and commercialise a novel borate-based bioactive glass technology platform for wound care and haemostasis.
Nicolas Guggenheim, Head of Business Area Medical Technologies, said: “Across every treatment area, medical technology is changing rapidly.
“The acquisition of Mo-Sci and ETS gives us new capabilities to help our customers deliver innovative technologies and breakthrough treatments that will improve outcomes and patient care.”
Kimberly Day, the owner of Mo-Sci and ETS, said: “Mo-Sci and Heraeus have been in contact for many years and prior to his passing, Ted identified Heraeus as a preferred partner to take Mo-Sci and ETS to the next stage of development.
“I am glad to carry this vision through to completion.”
Both Mo-Sci and ETS are based in Rolla, Missouri, USA.
Heraeus plans to keep the existing Mo-Sci team and facilities in Rolla and the acquisition is expected to close by the end of 2021, pending legal clearance and satisfaction of customary closing conditions.
