Flat Chopped Glass Fibers

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.

Flat chopped glass fibers are used across multiple industries for reinforcement and insulation purposes.

• Injection molding – improved flow and dimensional stability
• Construction materials – added durability and tensile strength
