Abstract
The invention relates to a ceramifying composition for forming a fire resistant ceramic under fire conditions the composition comprising: (i) at least 10% by weight of mineral silicate; (ii) from 8% to 40% by weight of at least one inorganic phosphate that forms a liquid phase at a temperature of no more than 800° C.; and (iii) at least 15% by weight based on the total weight of the composition of a polymer base composition comprising at least 50% by weight of an organic polymer.
Claims35
A ceramifying composition for forming a fire resistant ceramic under fire conditions, the composition comprising:
- (i) at least 10% by weight of silicate mineral filler;
- (ii) from 8% to 40% by weight of at least one inorganic phosphate that forms a liquid phase at a temperature of no more than 800° C.;
- and
- (iii) at least 15% by weight based on the total weight of the composition of a polymer base composition comprising at least 50% by weight of an organic polymer;
- wherein the composition forms a self-supporting ceramic on exposure to an elevated temperature experienced under fire conditions.

A ceramifying composition for forming a fire resistant ceramic under fire conditions, the composition consisting essentially of:
- (i) at least 15% by weight, based on the total weight of the composition, of a polymer base composition comprising at least 50% by weight of an organic polymer;
- (ii) 8-40% by weight of at least one inorganic phosphate that forms a liquid phase at a temperature of no more than 800° C., based on the total weight of the composition;
- (iii) at least 10% by weight, based on the total weight of the composition, of silicate mineral filler;
- and
- (iv) optionally additional inorganic filler in an amount of up to 30%;
- wherein the composition forms a self-supporting ceramic on exposure to an elevated temperature experienced under fire conditions.
