The present invention relates to inorganic-organic hybrids (IOHs), methods for their preparation and their use as fire resistant materials or components of fire resistant materials. More specifically, the invention relates to polyamide fire resistant formulations containing IOHs which have application in the production of fire resistant articles or parts thereof for use in the transportation, building, construction and electrical or optical industries.

A fire retardant darkening screen for use in greenhouses is provided, the screen including a top fabric and a bottom fabric. The top fabric includes halogen-containing polymeric strips laminated with a light-reflective film or foil. The bottom fabric includes polyolefin tapes, preferably high density polyethylene tapes, the polyolefin tapes including a synergistic fire resistance composition.

Method for the preparation of a film forming flame retardant comprising nitrogen and silicon in its chemical composition, said method comprising the following steps: i. conversion of Z.sub.1 moles of amine moiety, selected from the group of primary and secondary amine and covalently bound to Z.sub.2 moles of one or more at least partially hydrolysable silane moiety, with Z.sub.3 moles of a chemical substance selected from a group of chemical substances obtainable from carboxylic acids or carbonic acid and represented by formula (I), (II) or (III); ii. conversion with a with at least one HO-functionalized substance of formula (IV): M.sub.x(OH).sub.yR.sup.5z. The resulting film forming flame retardant is contemplated.

The invention relates to the use of organic oxyimide salts as flame retardants for plastics and to a corresponding flame retardant plastic composition. The invention also relates to a method for producing said type of plastic composition or a moulded part produced therefrom, a moulding compound, a moulded part, paint or a coating.
