IMS Strong Board

IMS Strong Boards are produced from refractory fibre compositions specailly developed to give rigid, self-supporting boards with excellent high temperature properties.

IMS strong board is designed for use in applications requiring higher rigidty than blanket forms. Because of its higher density, it offers improved thermal insulation properties and good abrasion resistance.

IMS strong boards are manufactured using our vacuum forming process. The process allows the production of white boards in a wide dimensional choice, offering excellent homogeneity throughout the thickness which allows for high definition machining of the board.

IMS strong board is produced by the additon of selected refractory fillers to the ceramic fibre in order to improve its mechanical properties. Strong board has two times the strength of 1260 board, both when measured fired and unfired.

All board fomualations contain a small amount of organic binder to improve the cold handling strength and this burns out on first firing at approximately 200-300°C. Heat treatment can be made to burn the organic binders on special request.
