The addition of polypropylene fibers enhances the crack resistance, tensile strength, and toughness of the mortar. For example, polypropylene fibers can increase the tensile strength, flexural strength, and shear strength of the mortar matrix while improving its fatigue resistance.
Widely used in rendering mortars, interior and exterior wall putties, thin-layer insulation mortars, grouting mortars, self-leveling floor mortars, and more.
