Glass Fiber
In 1971, the Company entered the glass fiber business when it established the subsidiary Central Glass Fiber Co., Ltd. Then, we established the subsidiary Central Glass Wool Co., Ltd. to produce glass wool in 1982. At that point we began supplying both glass fiber and glass wool. In 2012, we merged both companies and integrated their operations as Central Glass Fiber Co., Ltd.

Glass fiber
Glass fiber is a 6-24 micron thin filament-shaped fiber. It is made by ejecting molten glass, which is melted in approximately 1,500 degrees centigrade furnace (kiln), through platinum nozzles. Basic materials for various applications can be made by bundling these minute fibers together and processing them. For its excellent properties, such as breaking strength, electrical insulation, heat resistance, and chemical resistance, make them suitable for a wide range of applications, from housing equipment, automobiles, and vessels (pleasure boats, etc.) to electronics such as computers.

-
Milled Fiber
It is a powdered product made by grinding glass fiber in a special method, which improves physical properties such as thermal property and dimensional stability while maintaining the excellent surface finishes of the product.

Chopped Strand Mat
Glass fibers are formed into a sheet (non-woven fabric). The base material strength is not directional and it is widely used as a base material for hand layup molding in applications such as vessels, vehicles, laminates, and a FRP waterproof construction base material.
