VERMICULATE
Vermiculate is an insulating board material with raw material of Vermiculate and a special binding material.
The Vermiculate advantage :
- Thermal shock resistance, can be used in parts of furnace that are directly related to heat.
- No smoke during heating
- Low Thermal conductivity.
- High electrical resistance
- High thermal resistance
- Good chemical resistance to acids, alkalis and exhaust gases
- Rigid and stable with sufficient mechanical stability
Aplication Area:
Insulation material for furnaces as back up for lining, Boilers, Vessels and tanks
MICROPOROUS (MICROBOARD) INSULATING BOARDS
Microporous (Microboard) Insulating Board is an insulating material that has lowest thermal conductivity. The material is made from nano-porous material using a special binder. This material can use a layer of aluminum foil on one layer, or both layers, and also use PE foil layer on one layer, or both layers.
