Special polyurea lubricating grease for sintering machine
DESCRIPTION
This product is made of refined mineral oil thickened with an organic thickener and added with high-efficiency additives. It is used for lubrication and sealing of sintering machine slideways and other sliding friction parts that require lubrication and sealing under high temperature conditions.
Advantage
◎Excellent oxidation stability to prevent grease from deteriorating at high temperatures;
◎Excellent high temperature performance, no dilution or loss under high temperature conditions, ensuring good lubrication of the slideway;
◎Excellent sealing performance, good slideway sealing effect, reducing air leakage rate, improving sintering efficiency and sintering quality;
◎Good pumping performance ensures grease supply to the centralized lubrication system; good lubricity protects the slideway and reduces wear.
Application
◎ Suitable for lubrication and sealing of sintering machine slideways and other sliding friction parts that require lubrication and sealing under high temperature conditions.
◎Temperature range: -20℃-180℃
