Post-crack flexural strength and toughness
Unlike other structural fibers, PVA is hydrophilic, causing it to form a molecular bond with the matrix during hydration and curing. This unique combination of bond strength, tensile strength and high modulus of elasticity gives KURALON™-reinforced concrete substantial tensile and flexural strength.
KURALON™ is difficult to be pulled out from concrete matrix and can bridge between internal surface of cracks.
=> KURALON™ prevents cracks from growing wider and concrete board can be bent more without breaking.
