Maxtop fatty acid ester fire resistant hydraulic oil (MTFAE) is a kind of fatty acid ester fire resistant hydraulic oil made from fatty acid ester as the base component, adding a variety of functional agents such as anti-wear agent, oiliness agent and rust inhibitor. High flash point and spontaneous ignition point: will not burn in the event of fire, providing a high level of fire protection. Safe use: Suitable for high temperature or open fire environment to avoid fire accidents. High temperature performance: can maintain performance at high temperature, suitable for high temperature working environment. Stable viscosity: Viscosity that remains stable under temperature changes.
