PP Fiber — Polypropylene Fiber

High-tenacity monofilament and fibrillated fibers that control cracking and improve durability of concrete and mortar.

CAS No. 9003-07-0 HS Code 3902.10 (CN export 39021000) EINECS 202-316-6

Simple Addition, Big Durability Gain

PP fiber disperses evenly in concrete or mortar to form a three-dimensional support network that resists plastic shrinkage cracking.

✓

Crack control — effectively reduces plastic shrinkage and settlement cracks.

✓

Impact & abrasion resistance — tougher, longer-lasting concrete surfaces.

✓

Easy to use — just add to the mixer; no change to mix design or equipment.

✓

Alkali resistant — stable in high-alkali cement environments.
