Professional Polypropylene Synthetic Microfiber Supplier
Tenabrix® polypropylene microfiber offers multiple benefits to elevate the quality and reliability of your concrete or mortar.
Enhanced Impact & Seismic Resistance
Reinforced with polypropylene fibers, concrete gains increased impact and seismic resistance, making it ideal for high-performance projects where structural strength is critical.
Superior Water Resistance
By enhancing the impermeability of concrete, our microfibers help block water infiltration, protecting the structure from damage and ensuring long-term durability, even in moisture-prone environments.
Thermal Stability
Minimize the risks of thermal expansion and contraction, which are common causes of cracking, by using Tenabrix® microfibers. Our fibers help maintain the integrity of concrete under varying temperature conditions.
Environmental & Chemical Resistance
Polypropylene fibers are highly resistant to chemicals and corrosion, ensuring that your concrete can withstand harsh environmental conditions and extend its lifespan in aggressive environments.
