"In 1961, two years after graduating from Villanova University, chemical engineer Ted Flint and a colleague founded Penn Valley Polymers in Phoenixville, PA to manufacture polysulfide sealants for construction and insulating glass.

These talented partners soon developed high-quality products that outperformed other commercial materials available, and business grew well. But in 1966 fire destroyed Penn Valley Polymers’ factory. With no production and insufficient capital to rebuild, the business was sold.

In December 1969 Ted Flint set out on his own, founding Polymeric Systems, Inc. (PSI) in a small, rented building in Pottstown, PA. Like its predecessor, PSI initially manufactured polysulfide-based insulating glass sealants. It was a one-man, one-woman operation: Ted handled product development, production and sales while his wife Debby kept the books and delivered finished goods.

The business grew but was limited in scope because of the lack of product diversity. Then, in 1972, came the first breakthrough."
