Imerys exhibited and presented at this week’s UNITECR, a key technical conference for the refractory industry. Experts from the Group discussed new products, sustainability and how to support young professionals in the industry.
As it seeks to take on the challenges and opportunities of the future, Imerys needs partners in innovation with whom it can fully leverage the latest emerging and transformative research.
Calcium aluminate has been used in sewer environments since the 1940s. Initially, the drivers for its use included its resistance to sulfates in soil, rapid return to service and superior abrasion resistance.
The team's joint efforts brought recognition from the Center for Disease Control and Prevention (CDC).
