Single yarn

Nittobo manufactures and sells various types of single yarn for printed wiringboards and industrial materials. It meets customers' needs by offering a unique product lineup that includes several types of glass fiber yarn, tex yarn counts, and filament diameters.

Each single yarn product of the highest quality is manufactured under rigorous quality control.

E-glass yarn

■ For printed wiringboards

Nittobo's E-glass yarn for printed wiringboards consists mainly of single yarn produced by twisting strands that comprise 4.0–7.4µm filaments. Its E-glass yarn products, which excel in electric insulation, heat resistance, tensile strength, and dimensional stability, are generally used for printed wiringboards. Nittobo offers workable E-glass yarn that features highly stable quality, which has been surface-treated for use in weaving.

T glass

Nittobo's T glass is superior even to E glass in terms of tensile strength, heat resistance, and dimensional stability. T-glass yarn is used for special printed wiringboard and industrial materials, contributing to making composite materials more efficient.

  • * Currently, Nittobo is not selling T-glass yarn, and only woven T-glass cloth is commercially available.
