Phosphoric acid flame retardant liquid EHC PLUS
Product Overview:
This product is formulated using phosphate esters as the base material, with the addition of antioxidants, anti-hydrolysis agents, and anti-corrosion additives. It exhibits a high ignition temperature of 545℃, excellent corrosion resistance, and good antioxidant properties. It effectively prevents the decomposition of phosphate esters caused by water contamination.
Scope of Application:
This product is suitable for hydraulic systems that require flame-resistant properties, especially those with high fire hazards such as power hydraulic control systems. In case of leaks, ruptured oil lines, or other reasons, the hydraulic oil may come into contact with heated surfaces during processing, posing potential risks. This product can prevent such hazards from occurring.
Precautions:
This product should not be mixed with water-glycol or emulsified hydraulic systems. It may also have a certain impact on seals made of neoprene rubber. However, it is suitable for use in applications that employ sealing materials such as silicone, polytetrafluoroethylene, and fluororubber.
