What is glass fiber?

History and overview

Glass fiber is the first industrially produced inorganic fiber that is widely used in industry for such characteristics as strength, resistance to heat and chemicals, nonflammability, and electric insulation.
In Japan, Nittobo succeeded in the industrialization of glass fiber production in 1938, and later, in the prewar and postwar periods, the production of glass fiber continued to develop rapidly.
In recent years, glass fiber has been used for a wider range of purposes, including construction materials, fiber-reinforced plastics, and electric insulation fabric for printed wiringboards, and its excellent characteristics are widely recognized in industries worldwide.
