Abstract:

A Polyalphaolefinester base fire resistant hydraulic fluid was reformulated to include chlorotrifluoroethylene CTFE as an additive to enhance fire resistance. CTFE was added to the formulation at 2-10 by weight. Each of the formulations were evaluated for performance and flammability. Addition of the CTFE was found to promote excess foaming when tested for foaming characteristics. The formulations were adjusted to include an anti-foam additive to counteract this effect. The new formulations were found to provide satisfactory performance and improvement in fire resistance. Addition of CTFE increased the flash and fire points of the fluid. In addition, the autoignition temperature, hot manifold spray ignition temperature were both increased above what is available from MIL-HA6147O, the current military specification fire resistant hydraulic fluid.
