History of Saflex and Vanceva

In 1938, Monsanto began manufacturing PVB resin in a joint venture with Shawinigan Resins of Canada, which resulted in the production of the Saflex brand interlayer at its adjoining plant in Springfield, Massachusetts. These early interlayers offered vastly improved processing and windscreen performance compared to previously used cellulose acetate and quickly displaced it in this application.
By the early 1950s, architectural use of laminated glass began to increase and colored interlayer products were introduced for this application. Monsanto developed a process to put a gradient color band on the automotive interlayer and began offering it commercially in 1951.
In the early 1960s, Monsanto expanded its production facilities to Trenton, Michigan, and Ghent, Belgium, and introduced the first HPR (high penetration resistant) interlayer in 1965. This product approximately tripled the penetration resistance of windscreens, and federal standards requiring laminated windscreens in the United States were enacted in 1967.
In 1997, Monsanto’s chemical business was spun off to create Solutia, which merged with Eastman in 2012. Eastman remains fully committed to maintaining the leadership position of Saflex and serving the laminated glass market for years to come.
Eastman is recognized as a world leader in PVB interlayers and has continued to expand production facilities worldwide and meet new needs of the laminating industry with products offering superior processing, laminate performance and durability.
