Development of the unique technology behind GLASFLAKE™ began in 1963 at the Osaki research laboratory. In September 1969, the technology for commercial production was transferred to Nippon Glass Fiber Co., Ltd., which later became Technical Glass of NSG. GLASFLAKE™ was initially developed using a C-glass (alkali glass) composition, and launched commercially in 1972. To manufacture GLASFLAKE™, molten glass is blown up like a balloon and smashed while still soft. This results in a unique scale-like substance, which is resistant to acid and corrosion. In 1984, GLASFLAKE™ using an E-glass (non-alkali glass) composition joined the product lineup to enhance dimensional stability and anti-warping properties of thermoplastic resins. In 2011, C-glass GLASFLAKE™ was used in the paint for the Forth Bridge, a World Heritage Site in the UK.
