AP ST
GREASE (Transperent) - 15 KG
AP ST GREASE (Transperent) - 15 KG is a solid or semisolid
lubricant formed as a dispersion of thickening agents in a liquid lubricant.
Grease generally consists of a soap emulsified with mineral or vegetable oil.

GREASE (Transperent) - 15 KG
AP ST GREASE (Transperent) - 15 KG is a solid or semisolid
lubricant formed as a dispersion of thickening agents in a liquid lubricant.
Grease generally consists of a soap emulsified with mineral or vegetable oil.
A common feature of greases is that they possess a high
initial viscosity, which upon the application of shear, drops to give the
effect of an oil-lubricated bearing of approximately the same viscosity as the
base oil used in the grease. This change in viscosity is called shear thinning.
Grease is sometimes used to describe lubricating materials that are simply soft
solids or high viscosity liquids, but these materials do not exhibit the
shear-thinning properties characteristic of the classical grease. For example,
petroleum jellies such as Vaseline are not generally classified as greases.
Greases are applied to mechanisms that can be lubricated
only infrequently and where a lubricating oil would not stay in position. They
also act as sealants to prevent ingress of water and incompressible materials.
Grease-lubricated bearings have greater frictional characteristics because of
their high viscosity.
