Fiberglass Yarn for Insulated Sleeve Braiding

Fast wet-out and wet-through: The sizing chemistry of fiberglass yarn enables rapid resin penetration, fully saturating fiber bundles in seconds for efficient processing.

Strands are easily opened to expose their filaments: Low cohesion for fiberglass yarn allows strands to split uniformly, promoting complete filament separation without mechanical damage.

Good fiber dispersion: Uniform fiber distribution for fiberglass yarn eliminates resin-rich or dry areas, ensuring consistent composite quality throughout the part.

High composite mechanical properties: Optimized fiber-matrix adhesion for fiberglass yarn transfers loads effectively, delivering superior strength, stiffness, and impact resistance.

Minimal fuzz during processing: Robust sizing of fiberglass yarn protects filaments from abrasion, reducing loose fibers that can clog equipment or cause defects.

Low rate of dry abrasion over creel contact points: Engineered surface of fiberglass yarn reduces friction at guide points, extending component life and maintaining production uptime.

Ultra high strength, lightweight and high-strength: The finer the fiber diameter of fiberglass yarn, the larger the specific surface area, and the higher the bonding strength with the resin.

Excellent heat resistance and fire resistance: Fiberglass yarn is stable, non-combustible, and has a high melting point, ideal for high-temperature insulation, fireproofing, and wire/cable coating.

Excellent electrical insulation performance: Fiberglass yarn is a core PCB copper-clad laminate substrate and is widely used as motor and appliance winding insulation.

Good corrosion resistance: Fiberglass yarn resists acid/alkali corrosion, moisture, and aging, making it suitable for chemical, marine, and long-term outdoor use.
