From a fire-safety standpoint, resistance to ignition or spread of fire is recently becoming an important requirement of grease for industrial machinery applications. FR Grease we developed for centralised system can retard fire spread without compromising the lubricity. For the creation of FR Grease, base oil and additives were selected according to strict criteria with an emphasis on the property to prevent generation of combustible gas at high temperature, and a new manufacturing process was developed to ensure flame retardancy of the grease. FR Grease was developed based on our new finding that control of combustible gas generation is an effective way to put out flame when grease catches fire. Self-extinguishing FR Grease can provide safe operating environment for industrial machines where fire potential is a concern.
