Lubemater TK-R20 grease
Lubemater TK-R20 grease is a special high-performance lubricating and protective grease specially designed for the door sealing strips of rail transit vehicles. It is refined by using perfluoropolyether as the base oil and adding ultra-fine fine polytetrafluoroethylene thickener and other functional additives.
Lubrication of rubber sealing strips for the doors of various rail vehicles (such as subways, light rails, trams, high-speed railways, EMUs, conventional trains, intercity trains, etc.). The application temperature range is -40℃ to 120℃
Packed in 1kg iron drums
Core Advantage
1. Excellent low-temperature performance: Ensure the reliable operation of the sliding door in severe cold and reduce the failure rate;
2. Excellent anti-wear performance: The addition of fluorine-modified nano-solid addictives helps to improve fretting wear caused by frequent door opening and closing, reducing surface damage during long-term use. 3. Chemical stability: Not affected or eroded by chemical substances such as sulfuric acid, fuming nitric acid, hydrofluoric acid/hydrochloric acid, strong oxidants, water/water vapor, etc.
4. Good compatibility with substances such as metals, plastics, rubber and nylon;
