$Heat exchanger refractory insulation block$

Product Brief Description:

BW Vermiculite board is consists of vermiculite layered silicate, which are pressed with special additives under high pressure to moldings.

Designed for a maximum service temperature of 1,200°C (2,192°F). Suitable for condensing gas boiler heat cells, where working fast soaking by condensing water and gas fire drying, the board can keep the same performance in fireproofing and insulation. After the recycled soaking and drying, it can improve the purity and performs better on insulation.

The vermiculite board will not delaminate, pulverize or decompose, designed for working service life of more than 10 years.

Key Features:

● No pulverization

● No cracking

● No delamination

● No pollutant produced

● Small heat shrinkage ratio

● Long service life( ideally >15 years)
