Duratec 1000


Promat Duratec materials are “technical ceramics” made from calcium silicate, it acts as a high quality asbestos replacement board.  They are formulated without the use of asbestos fibres, and are thermally and electrically insulating materials for high temperature insulation use. Duratec is available in two different grades Duratec 750 which exhibits higher strength and Duratec 1000 exhibits low shrinkage.
