Main Applications

1

Water/glycol-based hydraulic fluid 

Most hydraulic fluids used in hydraulic equipment are mineral oil-based hydraulic fluids. However, because they are flammable, there is a risk of fire if they are used near ignition sources. In such locations, water/glycol-based fluids are used, which are based on water, which does not burn, and to which polyalkylene glycol-based lubricants, such as NEWPOL 75H-90000, described below, are added to give the water appropriate viscosity and lubricity. 

General characteristics of water/glycol-based hydraulic fluids include flame retardancy, no risk of fire, low flow point, high viscosity index, excellent shear stability, and no stickiness. 

Recommended grades:  NEWPOL 75H-90000, NEWPOL V-10-C 

2

High-temperature lubricants

The use of mineral oil-based lubricants at high temperatures has been considered extremely difficult due to the carbonization and sludging of mineral oil. 

 Polyalkylene glycol-based lubricants such as NEWPOL LB-300X contain antioxidants and are resistant to oxidative decomposition even when exposed to high temperatures. Even if oxidative decomposition occurs, the products will volatilize or dissolve in the lubricant and produce almost no carbonization or sludge, so they will not burn metals or other materials.

Because of these characteristics, it is used as a base oil for lubricating gear chains and bearings that are operated at high temperatures in cement manufacturing equipment, ceramics manufacturing equipment, glass manufacturing equipment, and plastic processing machines. 

Recommended grade:  NEWPOL LB-300X, LB-650X, LB-1800X, LB-400XY
