Polyvinyl Alcohol (PVA) Fiber

Polyvinyl Alcohol (PVA) fibers are high-performance additives that can be added to concrete and mortar. What makes PVA fibers unique is their ability to create molecular bonds with the concrete or mortar resulting in a bond that is up to 300% stronger than the bond others fibers can create.

The benefit of adding Polyvinyl alcohol fibers into concrete is their ability to increase crack resistance and the elasticity. Furthermore, they have beneficial effects on the tensile and molecular bond strength, and resistance to alkali, UV, chemicals, fatigue and abrasion.


PVA Fibers are commonly used in Thailand.
