| DESCRIPTION |
Lamtuf Phenolic Asbestos Sheets are manufactured using
heavy weave
Asbestos cloth impregnated using phenolic resin with or without graphite
graphite addition depending upon customers
requirement. The principle
feature of this material is its ability to operate at much high temperature
than phenolic paper or cotton grade
material. The material is used for
wide varieties of bearing application & general mechanical components
in high temperature situation. It is not recommended for primary
insulation for electrical application
at any voltage. This can be lubricated by almost
any liquid including water/emulsion,
chemical liquors or by conventional
method using oil/grease or dry lubricants.
The graphite mixed phenolic asbestos sheet is better in lubrication as
graphite is dispersed uniformly through out the structure to assert the
lubrication under bounding condition. |
