MF-06 is a short, fine-denier polyvinyl alcohol fiber developed as a formulation aid for cement-based mortar, wall putty, skim coat, repair mortar, and other thin-section products. Its 6 mm cut length is intended to distribute through fine aggregates and powders more readily than longer reinforcement fibers, helping formulators control early microcracks without introducing a coarse visible texture.

PVA has a hydrophilic surface and strong affinity with cement hydration products. In a compatible mix, dispersed MF-06 filaments bridge developing cracks and redistribute local stress. The grade is a crack-control component, not a replacement for structural reinforcement, movement joints, correct curing, or a sound substrate.

PropertyTypical value
PolymerPolyvinyl alcohol (PVA)
AppearanceWhite chopped fiber
Cut length6.0 ± 0.5 mm
Linear density2.0 ± 0.25 dtex
Nominal diameterApproximately 14 μm

Hot-water solubility, 90°C for 1 hour≤2.0%

These values use the same industry logic seen in public high-strength, high-modulus Chinese PVA fiber data: fine fiber around 2 dtex, tensile strength at or above 1,200 MPa, modulus above 30 GPa, low elongation, and density near 1.29 g/cm³. Test method and conditioning must be stated when comparing suppliers.

Where MF-06 fits

  • cement-based wall putty and skim coat;
  • dry-mix plaster and render;
  • tile-setting and repair mortars;
  • non-structural patching compounds;
  • fine precast and thin cementitious products.

The expected benefit is control of plastic-shrinkage and early microcrack development. Final effects on water demand, workability, flexural behavior, surface finish, and cracking depend on fiber dosage, powder grading, admixtures, mixing sequence, curing, and substrate movement.

Mixing and trial guidance

In a factory dry-mix process, pre-blend MF-06 with a free-flowing powder fraction before introducing it to the full batch. In wet batching, meter the fiber slowly into a moving mix rather than tipping a compact mass into water. Continue mixing only until the fibers are uniformly separated; excessive mixing can add air or change workability.

Start with a controlled dosage ladder in the buyer’s complete formulation. Record spread or flow, entrained air, finishing, fiber-ball count, crack response, adhesion, and strength. If workability falls, review the mixing sequence and admixture balance before simply adding more water.

Frequently asked questions

What is MF-06 designed for?

MF-06 is a fine 6 mm PVA fiber intended for dispersion and microcrack-control trials in mortar, cement-based wall putty, skim coat, repair compounds, and thin cementitious products.

What is the typical diameter of MF-06?

The nominal diameter is approximately 14 micrometres, corresponding to about 2.0 dtex. Confirm the current shipment specification and batch COA before approval.

How should MF-06 be added to a mortar mix?

For most dry-mix systems, distribute the fiber through the dry powders before adding water. Add it gradually, use enough mixing energy to separate the filaments, and check the wet mix for fiber balls.

Can I request a sample?

Yes. Milorez provides a free sample for laboratory evaluation. Commercial supply starts at one 20-foot FCL, approximately 12–15 tonnes depending on packing.
