Flat Chopped Glass Fibers

High-performance chopped glass fibers with modified oval cross section.
Enhancing liquidity, dimensional stability, and tensile strength in injection molding and composite applications.

Advanced Reinforcement Fibers for Plastics and Composite Materials

Flat chopped glass fibers are high-performance chopped strands engineered with a modified oval cross section, unlike conventional round fibers. This unique geometry provides superior flow properties in injection molding, increased dimensional stability, and improved tensile strength, making them ideal for advanced composite and plastic applications.

These fibers also offer excellent resistance to heat and chemicals, nonflammability, and reliable electrical insulation, extending their use to construction materials and printed wiring boards.

NAGASE supplies flat chopped glass fibers worldwide, delivering consistent quality, technical expertise, and global logistics support for plastics, electronics, and construction industries.
