ButaPhalt Archives

ButaPhalt® is an innovative cross-linking agent that helps improve the effectiveness of sulfur to cross link the SBS polymers with bitumen during the manufacture of polymer modified bitumen (PMB). It also helps in improving the thermal stability and storage stability of the PMB. A unique blend of proprietary ingredients, ButaPhalt acts as a H2S scavenger, helping reduce the hydrogen sulfide (H2S) emission and odor. It is easy to use in a PMB operation and is safe to handle and use. A more effective cross-linking agent, low levels of ButaPhalt deliver the desired results. ButaPhalt also helps in reducing the amount of polymer needed to meet the established specification and deliver the desired performance. The product is available both as a free-flowing, dust-free powder and as a liquid.

Sripath Asphalt Additives and Proven Durability in Roadway and Roofing Applications

In modern asphalt mix design, the use of high-quality asphalt additives has become essential to improve performance, sustainability, and long-term durability.
