Abstract (en)
[origin: EP0244964A1] Flexible intumescent sheet according to British patent 1 513 808, comprising heat-expandable micaceous mineral, inorganic fibrous material and organic binder, is made on standard board-making machinery incorporating a winding drum, so that a laminar product is obtained, not a monolithic one. The mineral particles in the sheet are thus more uniformly distributed across its thickness, and the product shows less tendency to premature failure in use.
