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.
What Asphalt Crosslinking Actually Does and How ButaPhalt Is Different
Polymer modified bitumen (PMB) is a cornerstone of asphalt mix design, enabling pavements that can resist rutting, cracking, and aging under increasingly demanding traffic and climate conditions. While polymers provide the backbone of these performance improvements, the real durability of PMB depends on how effectively those polymers interact with the base bitumen. That interaction is where crosslinking plays a critical role. Crosslinking is often [...]
