Characteristic:
Expanded vermiculite insulation brick is refractory products made of expanded vermiculite as the main raw material. When expanded vermiculite is used as the insulation materials, we can directly use the expanded vermiculite particles as the filling materials for the insulating layer. The fire-resistant property of the expanded vermiculite products is inferior, can easily have deformation when bear heavy load. The general should not be used for load-bearing structure in addition to the products with high density. The expanded vermiculite insulation brick is one of thermal insulation brick and its main chemical composition is expanded vermiculite.
Application:
Generally speaking, it is used insulating layer .where temperature is under 1000℃.
