Achieve Desired PMB Grade and Performance

ButaPhalt® is an innovative crosslinking additive specially engineered to improve PMB performance by allowing sulfur to more effectively form the bridges in Polymer Modified Bitumen, resulting in better PMB stability.

It helps reduce hydrogen sulfide (H₂S) emissions and odor, providing improved working conditions and a safer approach to crosslinking technology.

ButaPhalt® improves productivity and provides better thermal stability compared to traditional crosslinkers or elemental sulfur. A production friendly product, it helps reduce operational costs. It is also highly dosage efficient with low levels of ButaPhalt® delivering desired results.

ButaPhalt® maximizes crosslinking efficiency, allowing manufacturers to achieve desired performance with minimal additive concentrations. It is easy to use in a PMB operation, safe to handle, and helps reduce waste and backhaul charges.

Key Advantages

ButaPhalt® improves PMB binder quality and working conditions while resolving common processing bottlenecks.

  • Mitigates Hydrogen Sulfide Gas: Reduces emissions and foul odors for significantly safer, more compliant working environments.

  • Improves Reaction Speed: Optimizes crosslinking kinetics, to reduce processing times and boost plant productivity.

  • Improves PMB Binder Stability: Prevents phase separation and maintains structural homogeneity during hot storage and paving service life by creating robust, high-energy linkages.
  • Prevents Equipment Fouling: Protects blending units, storage tanks, and transfer pumps from build-up by eliminating the risks of over-vulcanization or localized gelation.

FAQs: ButaPhalt® Crosslinking Additive

1. What is ButaPhalt® used for?

ButaPhalt® is used as a crosslinking additive in the production of Polymer Modified Bitumen (PMB). It is designed to improve crosslinking efficiency, PMB binder stability, production productivity, and thermal stability while helping reduce hydrogen sulfide (H₂S) emissions and odor.

2. How does ButaPhalt® improve PMB stability?

ButaPhalt® improves PMB stability by optimizing the crosslinking reaction between polymer and bitumen. Its chemistry establishes strong, direct monosulfide linkages that help maintain a more stable and homogeneous PMB structure, reducing the risk of continued crosslinking reactions and phase separation during hot storage and paving service life.

3. How does ButaPhalt® compare with sulfur as a PMB crosslinker?

ButaPhalt® is designed to optimize the crosslinking reaction pathway by establishing short, direct monosulfide linkages rather than forming fragile polysulfide chains. These stronger molecular bonds contribute to improved PMB stability and thermal performance while supporting efficient, accelerated crosslinking at low additive concentrations.

4. Does ButaPhalt® reduce H₂S emissions during PMB production?

Yes. ButaPhalt® helps mitigate hydrogen sulfide (H₂S) gas and associated foul odors during PMB production. Reducing H₂S emissions can contribute to safer, more comfortable working conditions while addressing an important operational challenge associated with sulfur-based crosslinking.

5. How does ButaPhalt® help reduce PMB production time and operating costs?

ButaPhalt® is designed to improve crosslinking reaction speed and dosage efficiency, helping PMB producers reduce processing time and improve plant productivity. Its production-friendly formulation also helps reduce operational costs, waste, and backhaul charges while achieving desired PMB performance with relatively low additive concentrations.

6. What ButaPhalt® grades are available

ButaPhalt® is available in two grades: a free-flowing, dust-free powder and a pumpable liquid suspension. Each form is offered in Performance and Ultra Fast options. The Ultra Fast Grade is highly dosage efficient and can achieve similar results to the Performance Grade at approximately half the dosage, giving producers flexibility based on their production requirements.
