Vermiculite Fireproof Boards
Vermiculite is a naturally occurring aluminium-magnesium silicate layer that expands with the application of heat. This expansion process is called exfoliation and the resulting material is used in bulk form or processed to boards by a press forming process. The board can be worked easily with wood working tools. It can be sawn, drilled and sanded.
It is harmless to the environment.and it hasn't formaldehyde, benzene, toluene and xylene by the test.
It could be formed by tooling as per the drawing.
