Abstract
A flexible fire and heat resistant material comprising an intimate mixture of organic intumescent filler and organic fibres adapted to char intensely within the temperature range of 200.degree. C. to 500.degree. C. The added presence of inorganic fibre components enhances the structural integrity of this structure both during char formation up to 500.degree. C. and at higher temperatures up to 1200.degree. C. once char oxidation takes place.
Claims29
A flexible fire and heat resistant material comprising an intimate mixture of organic intumescent filler and organic fibers, said organic intumescent filler and said organic fibers each being adapted to char intensely within the temperature range of 200.degree. C. to 500.degree. C.
A flexible fire and heat resistant material comprising an intimate mixture of organic intumescent filler and organic fibers, said organic intumescent filler and said organic fibers each being adapted to char intensely within the temperature range of 200.degree. to 500.degree. C. wherein the organic fiber is a hybrid fiber with both an organic and inorganic component.
A flexible fire and heat resistant material comprising an intimate mixture of organic intumescent filler and organic fibers, said organic intumescent filler and said organic fibers each being adapted to char intensely within the temperature range of 200.degree. to 500.degree. C., including a central layer comprising said intimate mixture of said organic intumescent filler and said organic fibers, and two outside layers of fiber which are separated from the central layer by two sheets of fabric, wherein the two sheets of fabric are made of organic fibers which char intensely within said temperature range.
