WHAT MAKES INTEGRITY ULTRAFIBERS DIFFERENT FROM CONVENTIONAL AR GLASS FIBERS?

WHY LOWER TEX MATTERS
Each kilogram of Integrity UltraFibers contains approximately 65% more reinforcing filaments than conventional 18 µm, 135 tex AR glass fibers. By using 14 µm filaments in optimized 200-filament bundles rated at 82 tex, these fibers provide greater reinforcement efficiency per pound.

CCI recommends a 2.5% fiber dose for Integrity UltraFibers versus the 3% typically required for conventional thicker fibers. This reduces material usage while maintaining or improving structural performance.

HIGHER TENSILE STRENGTH
In addition to increased filament count, Integrity UltraFibers exhibit higher than normal tensile strength. The combination of finer filaments and elevated tensile capacity produces improved crack resistance and enhanced durability in GFRC panels and cast elements.

CLEANER SURFACE APPEARANCE
Lower tex fibers reduce visual impact in architectural and direct cast concrete surfaces. This is particularly important for countertop and decorative GFRC work where fiber shadowing can affect finished appearance.

PROPRIETARY SIZING FOR MIXING PERFORMANCE
Sizing is a thin protective coating applied during fiber manufacturing to protect filaments during handling and mixing. Integrity UltraFibers uses a unique sizing formulation that:

• Maintains strand integrity under shear
• Prevents shredding during mixing
• Improves dispersion
• Enhances flow characteristics during casting

The result is more consistent reinforcement and easier placement.

CODE COMPLIANCE
Integrity UltraFibers are manufactured with zirconia content in compliance with:

ASTM C1666/C1666M-07
EN 15422

Production follows industry recommendations from PCI and GRCA for structural GFRC reinforcement.
