Inert Lubricants Oils – Greases – Waxes Halocarbon Inert Lubricants
Inert Lubricants Oils – Greases – Waxes Halocarbon Inert Lubricants Halocarbon oils, greases and waxes are polychlorotrifluoroethylenes (PCTFE), which are chemically inert and nonflammable lubricants with high thermal stability, good lubricity, high dielectric strength and low compressibility. Halocarbon was the first to commercially produce PCTFE-based lubricants over 60 years ago. We offer a wide range of oils, greases and waxes to meet industries' needs. The inertness of our lubricant is required for the safe handling of highly reactive and/or aggressive chemicals like oxygen, chlorine, hydrogen peroxide, sulfur trioxide and nitric acid. This unique chemistry can also provide advantage in many other applications from lab-scale to the production plant. Have Questions?

NASA Technology Roadmaps TA 6: Human Health, Life Support, and Habitation Systems
NASA Technology Roadmaps TA 6: Human Health, Life Support, and Habitation Systems May 2015 Draft 2015 NASA Technology Roadmaps DRAFT TA 6: Human Health, Life Support, and Habitation Systems Foreword NASA is leading the way with a balanced program of space exploration, aeronautics, and science research. Success in executing NASA’s ambitious aeronautics activities and space missions requires solutions to difficult technical challenges that build on proven capabilities and require the development of new capabilities. These new capabilities arise from the development of novel cutting-edge technologies. The promising new technology candidates that will help NASA achieve our extraordinary missions are identified in our Technology Roadmaps. The roadmaps are a set of documents that consider a wide range of needed technology candidates and development pathways for the next 20 years. The roadmaps are a foundational element of the Strategic Technology Investment Plan (STIP), an actionable plan that lays out the strategy for developing those technologies essential to the pursuit of NASA’s mission and achievement of National goals. The STIP provides prioritization of the technology candidates within the roadmaps and guiding principles for technology investment. The recommendations provided by the National Research Council heavily influence NASA’s technology prioritization. NASA’s technology investments are tracked and analyzed in TechPort, a web-based software system that serves as NASA’s integrated technology data source and decision support tool. Together, the roadmaps, the STIP, and TechPort provide NASA the ability to manage the technology portfolio in a new way, aligning mission directorate technology investments to minimize duplication, and lower cost while providing critical capabilities that support missions, commercial industry, and longer-term National needs.
