Fire-resistant seating, in particular aircraft seats, which consist of at least a soft, supporting material and a cover, between which there is a fire-resistant intermediate layer, which is a combustion of a layer of fiberglass fabric, which is firmly attached to the soft supporting material, and a layer of polyurethane foam, which has been rendered fire-resistant and is firmly attached both to the layer of fiberglass fabric and to the cover.

Fire-resistant seating, in particular aircraft seats

The present invention relates to a fire-resistant intermediate layer for covering articles of seating furniture that consist of at least a soft supporting material and a fire-resistant covering, and which fire-resistant intermediate layer comprises a combination of a layer (a) of polyurethane foam plastic rendered fire-resistant, which rests on the soft supporting material, and (b) a glass fabric which is situated on the layer of polyurethane foam plastic rendered fire-resistant.

Fire-resistant intermediate layer for covering articles of seating

A soil stabilizer based on a prepolymer with terminal isocyanate groups, obtained by reaction of polyol with a stoichiometric excess of polyisocyanate, said prepolymer being such that in water a substantially stable dispersion of polyurea polymer particles is formed in the presence of a surface-active product.

Soil stabilizers and their preparation

The present invention provides a method to improve the rupture stability of polyurea foam materials to such a level that they can be applied on a commercial scale. This is achieved by incorporating 0.5 to 50 parts by weight of at least one alkanolamine having at least one amino group, one hydroxyl group and a molecular weight of from 47 to 2000 per 100 parts by weight of polyisocyanate used for the preparation of said polyurea foam materials. Preferably the foam material prepared is cut into pieces by cutting it in the rise direction, more particularly in the rise direction that is perpendicular to the machine direction of the foam, and subsequently crushing said pieces at least once.
