Meanwhile, this product also possesses performance features, including acid resistance, alkali resistance, corrosion resistance, mildew resistance, anti-moth & anti-aging properties. The product is non-toxic to humankinds, and free from pollution to the environment.
Main purpose
In the construction industry, this product is mainly used to replace asbestos in cement products and play the role of enhance. Its enhancement can be comparable with the effect of reinforcement. Meanwhile, it is not as harmful as that of asbestos. In the hydropower industry, this product can be applied to concrete dam reservoirs, making them more rugged and durable. In t he transport sector, this product can be applied to concrete bridges, tunnels, airport runways, highways, railway concrete sleepers, making them more strong, and secure. In addition, it can also be applied in the production of high-strength rope, safety net, ti re cord, rubber- reinforced materials, conveyor belts, fi re hoses, braided hoses.
