High Temperature Anti-wear Urea Grease
Overview:
This product is made of high viscosity refined base oil, thickened by urea thickener, added with special extreme pressure additive and many kinds of imported additives. It's a new generation of high temperature anti-wear grease.
Features:
Excellent high temperature resistance; Long service life and stable period under high temperature; Good lubricity under high temperature and heavy load shock or very bad conditions; Stronger EP AW (Extreme Pressure, Anti-wear) properties; No dispersing under high temperature and high speed; No changing after long time mixing with water, no wash away, minimizing the noise and vibration.
Application:
Applicable between -20ºC to +250ºC, this is a multipurpose grease, can be widely used in the lubrication of bearings in the high temperature service of metallurgy, chemical, textile, printing and dyeing, automobile, mine, oil field, coast defence, sugaring, paper making, plastic, etc.
