Excellent heat insulation performance Vermiculite for Sealing gasket filler plate
Product Description
Vermiculite(Mg0.5(H2O)4Mg3#91;AlSi3O10#93;(OH)2) is massively used in frictional surfaces industries.Its a very appropriate substitute for asbestos on brake pad which makes the pad like sponge.
Vermiculite is now used extensively in the friction lining industry (e.g. brake and clutch linings) as a safe alternative to asbestos, and plays an important role in this field.
Vermiculite has the properties of fire resistance, sound insulation, heat insulation, flame retardant and friction resistance.
Generally speaking, the basic requirements for brake pads are: wear resistance, high friction coefficient and excellent heat insulation performance.
Vermiculite has high strength and high temperature resistance, so it can meet the requirements of brake pad, clutch disc and pad. Vermiculite has strong wear resistance, can improve the wear resistance and friction of brake burning plate, absorb noise and bear high temperature of 1200 ºC.
The main size for brake pads are 20-40mesh, 40-60mesh
- improved coverage
- lighter weight
- improved workability
- excellent fire resistance
- reduced thermal conductivity
- improved adhesion to a wide range of backgrounds
- increased resistance to cracking and shrinkage.
