Vermiculite Grade 3

Description

Vermiculite is used as a filler in gypsums. The advantage vermiculite plasters have over conventional types of plasters are:

• improved coverage
• lighter weight
• improved workability
• excellent fire resistance
• reduced thermal conductivity
• improved adhesion to a wide range of backgrounds and increased resistance to cracking and shrinkage.

Vermiculite improves the resistance to chipping of plasters due to the ability of the particles to accommodate dimensional change. It is used as a growing medium in horticulture, and can be used in conjunction with hydroponics and potting mixes. Other uses include insulation, fire protection, refactory, spill absorption and can be used to replicate railway ballast on scale model sets.These granules are non-combustible, and are insoluble in water and all organic solvents. Expanded vermiculite is easily poured, is light, clean, highly absorbent and provides baffle against impact shock when used for packaging. Exfoliated vermiculite is used in the friction brake linings market, high temperature insulation, loft insulation, various construction products, animal feeds, and many other industrial applications. Vermiculite with its layered structure and surface characteristics, is utilised in products such as intumescent coatings and gaskets, the treatment of toxic waste and air-freight packaging of hazardous goods.
