Wedge-Vermiculite Insulation Board

wedge w-vcl high temperature insulating boards are manufactured with base material exfoliated vermiculite and inorganic binders. 

​

the material is free of asbestos and organic substances. vermiculite is an aluminium-magnesium layer silicate, which bloats to ultralightweight granulates through heating and is processed to boards, bricks and shaped parts through a compression mould procedure.

​

advantages

• high thermal shock resistance.

• can be applied in the furnace at fire side.

• fireproof, non-combustible a1, excellent fire protection.

• no smoke nuisance during heating-up.

• low thermal conductivity.

• high electrical resistance.

• easy handling and installation.

• high thermal resistance.

• good chemical resistance to acids, alkalis and exhaust gases.

​

applications

• industrial furnace construction for thermal insulation.

• hot face directly in the furnace and backup insulation.

• widely used in aluminium melting furnace, steel ladle, tundish, torpedo ladle, glass melting as backup insulation.

• household appliances: night storage heaters, boilers, hearths, vessels and tanks.

• fireplace linings, hot stove.

• resistant to co and ch4 atmosphere;

• non wetted by fluid aluminium, kryolite and flouride.
