Composite Technologies International (CTI) was founded in 2015 by Stephen Gleason to fulfill a need for a true composite reinforcement in the composites industry.  CTI’s parent company, Performance Minerals Corp. (PMC), was founded in 1993 and has grown to supply over 90% of the calcium sulfate used within the bath market.
