Polypropylene crack resistant fiber is a high-strength bundle monofilament organic fiber formed from fiber grade polypropylene through special processing technology. It has inherent resistance to strong acid and alkali, weak thermal conductivity and extremely stable chemical properties. Adding it in the mortar or concrete can effectively control the micro cracks caused by temperature changes in the initial mould shrinkage stage of mortar and concrete, prevent and restrain cracking, and greatly improve the performance of crack resistance, impermeability, impact resistance and seismic capacity of concrete.
• Product performance
It can effectively control the microcracking caused by plastic contraction, dry shrinkage and temperature change of mortar and other factors;
Prevent and inhibit cracks formation and development;
It improve the cracking resistance,impermeability resistance,seismic resistance and shock resistance properties of mortar;
It also improve the durability of mortar.
• Recommended application
Cement-based surface mortar,gypsum based surface mortar,insulating mortar and thick layer rendering mortar.
