Sripath Launches ButaPhalt® to Advance PMB Performance

Sripath Technologies® LLC, Mahwah, New Jersey, has launched its innovative crosslinking additive, ButaPhalt®. In May 2025, Sripath acquired the “Buta Business” consisting of the assets of ButaPhalt Products LLC, ButaChem LLC, ButaMix LLC, and related businesses and activities.

ButaPhalt is the first product of the Buta Business being offered under the Sripath banner. ButaPhalt is an innovative crosslinking additive that is specially engineered to improve the performance of polymer-modified bitumen (PMB). It allows sulfur to more effectively crosslink with the polymer during PMB production, according to the manufacturer, which may help reduce the amount of polymer needed in a PMB mix to deliver desired performance. ButaPhalt is formulated from a proprietary blend of sulfur powder, accelerators, scavengers, surfactants, absorbing agents and specialty oils. The result is a product the manufacturer states is a more effective crosslinking additive as well as highly dosage efficient.

The company states: “ButaPhalt is available as both a free-flowing, dust-free power and as a pumpable liquid suspension for easy handling. ButaPhalt powder also helps reduce waste and backhaul charges. ButaPhalt typically improves productivity, reduces processing time, and lowers operational costs. ButaPhalt is an operations-friendly product that is easy to use and safe to handle. It can reduce hydrogen sulfide (H2S) emissions and odor typically associated with PMB production. It helps improve working conditions while mitigating potential environmental impacts. ButaPhalt improves the thermal stability of a PMB. It easily delivers desired PMB performance.”

“We’re incredibly proud to add ButaPhalt to Sripath’s product portfolio,” said Dr. Krishna Srinivasan, president of Sripath Technologies. “We believe it fills a need in the industry for high-performing crosslinkers that improve polymer modified bitumen performance and grade more effectively than traditional solutions.”

“From a technical perspective, ButaPhalt has been and continues to be a significant step forward in crosslinker technology,” said Dennis Krivohlavek, business development specialist for Sripath Technologies. “Its proprietary formulation delivers greater stability, consistent performance, and enhanced ease of handling for producers. We’ve designed it to integrate seamlessly into PMB production, helping our customers optimize their processes while meeting stringent performance specifications.”
