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.
ButaPhalt: Advancing PMB Performance and Safety Featured in Roads & Infrastructure Australia
Sripath Technologies’ innovative approach to polymer modified bitumen (PMB) crosslinking and pavement performance has been highlighted in the December 2025 issue of Roads & Infrastructure Australia. The feature focuses on ButaPhalt®, Sripath’s innovative crosslinking additive, which is designed to address long-standing industry challenges while enhancing both performance and safety in PMB production. Polymer modified bitumen plays a crucial role in creating high-performance, durable roads capable of withstanding heavy traffic and challenging conditions. However, maximizing its performance [...]
