Miles biosyn FR is formulated to offer superior fire resistance and enhanced lubrication and protection. Unlike most water soluble glycol based formulations, Miles biosyn FR is far easier to maintain, has an exceptionally long fluid life, and, offers superior pump protection. It is non-toxic and non-hazardous, and its exceptional oxidative stability, corrosion resistance, and anti-wear properties make it particularly well suited for applications where other fire resistant fluid technologies are restricted.
