In FY24, for the development of high oleic soybean oil (HOSO) based Fire Resistant Hydraulic Fluid (FRHF) and Environmentally Attractive Lubricants (EAL), through the first round of Factory Mutual (FM) screenings and various internal tests, we successfully pinpointed which raw materials were affecting fire safety. Additionally, we identified successful combinations from well-established chemistry that could guide our next formulation revisions. Our collaboration with Petro-Lubricant Testing Laboratories, Inc. (PLTL) also yielded breakthrough insights from the spray ignition test, revealing specific additive technologies that would significantly improve our chances of meeting the required standards. Armed with these valuable findings, we are now designing experiments to finalize a new formulation with much higher confidence of passing both FM and Mine Safety and Health Administration (MSHA) approvals required for commercialization for fire resistant usages and mining applications.
Our current recently developed EALs already deliver exceptional results, surpassing industry specifications in many areas. However, to ensure these products can be used safely in underground mining—a key market for us—we are focused on further improving fire safety.
Once we complete the design of experiments, incorporating the key learnings from FM and PLTL screenings, we will submit the revised FRHF samples for a second round of testing to confirm the formulation's performance before seeking final approval from FM and MSHA. The results of this second screening will also help us finalize the EALs. If needed, we will conduct additional tests, including FZG wear, Vickers Vane Pump durability, material compatibility, bioaccumulation, biodegradation, and aquatic toxicity, to ensure the highest quality and compliance standards.
Overall, our efforts have significantly advanced our understanding and capabilities, bringing us closer to achieving fire safety standards while maintaining exceptional application and environmental performance.
