Production
PVB is a 80-year-old product. It has been the dominant interlayer material since the late 1930s. It is currently manufactured and marketed by a number of companies worldwide, including Sekisui (Kyoto, Japan)(Winchester, Kentucky) ("S-Lec" brand PVB film and powdered PVB resins). DuPont (Wilmington, Delaware, USA) ("Butacite"-brand PVB), Solutia (St. Louis, Missouri, USA) (Saflex-brand PVB), Kuraray Europe GmbH (Frankfurt, Germany) ("Trosifol"-brand PVB and "Mowital / Pioloform" for powdered PVB resins).
The market for laminated glass products is a mature one, and relatively stagnant. With only minor modifications, the PVB interlayer sold today is essentially identical to the PVB sold 30 years ago. Since its introduction in 1938, the worldwide market for PVB interlayer has been dominated by a handful of large chemical concerns. As a result, inventive efforts have tended toward methods of making the interlayer itself cheaper to manufacture, or making the interlayer easier to handle and less prone to material defects during the process of fabricating laminated glass panel.

Famous quotes containing the word production:
“... if the production of any commodity necessitates the sacrifice of human life, society should do without that commodity, but it can not do without that life.”
—Emma Goldman (1869–1940)
“The growing of food and the growing of children are both vital to the family’s survival.... Who would dare make the judgment that holding your youngest baby on your lap is less important than weeding a few more yards in the maize field? Yet this is the judgment our society makes constantly. Production of autos, canned soup, advertising copy is important. Housework—cleaning, feeding, and caring—is unimportant.”
—Debbie Taylor (20th century)
“To expect to increase prices and then to maintain them at a higher level by means of a plan which must of necessity increase production while decreasing consumption is to fly in the face of an economic law as well established as any law of nature.”
—Calvin Coolidge (1872–1933)
