摘要:
Crosslinked flame retardant thermoplastic elastomer gels are provided. The crosslinked flame retardant thermoplastic elastomer gels comprise a char catalyst, a char former, a maleic anhydride-modified styrene ethylene/butylene styrene polymer, and a softener oil. Methods are provided of making crosslinked flame retardant thermoplastic elastomer gels.
摘要:
Die vorliegende Erfindung beschreibt die Herstellung und Verwendung von vernetzten Gelmaterialien auf Basis kationisch modifizierter Polysaccharide, die sowohl auf porösen Oberflächen, z.B. aus Holz oder Papier, als auch auf glatten Oberflächen haften und dadurch eine deutlich längere Wirksamkeit als Brandschutzadditiv aufweisen. Ebenso ist die Verwendung von vernetzten kationisierten Polysaccharid-Derivaten als Additiv in wässrigen Formulierungen, die sowohl den vorbeugenden Brandschutz als auch das Löschen von Bränden effizienter gestalten, Gegenstand der vorliegenden Erfindung.
摘要:
A method of treating a material to improve flame retardancy, the method comprising applying to the material urea, phosphorous acid or a salt thereof, and a base5 comprising a monovalent metallic cation.

The instant invention relates to 3,3'-bis(3,4-dihydro-3-phenyl-2H-1,3-benzoxazin-6-yl)-1(3H)- isobenzofuranone and analogues based on phenolphthalein, formaldehyde and a primary amine. Such compounds are, when cured to form polymeric networks, difficultly inflammable and resistant to high temperatures. Such compounds may especially be used in the production of printed wiring boards.
摘要:
A method for protecting a structure or organism from the effects of fire caused by an explosion comprising covering at least a part of said structure or organism in a barrier comprising a water gel.
摘要:
The invention relates to a method for producing phosphorous-nitrogen compounds by reacting phosphorous sulfides with an amino component, which has at least one nitrogen atom with at least two hydrogen atoms or has at least two nitrogen atoms with at least one hydrogen atom. According to the invention, the desired phosphorous-nitrogen compounds are formed a temperature Tmax of >/= 200 DEG C. These compounds are preferably used as flameproofing agents in thermoplastic molding materials which, among other things and in addition to a thermoplastic polymer, can still contain a nitrogen compound, fillers, lubricants, common additives and/or common viscosity modifiers.
摘要:
The present invention is directed to silicone formulations which are capable of being rapidly cured to tough elastomeric materials through exposure to UV radiation, and optionally through exposure to moisture as well. The cured products demonstrate high resistance to flammability and combustibility.
摘要:
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 1 moles of amine moiety, selected from the group of primary and secondary amine and covalently bound to Z 2 moles of one or more at least partially hydrolysable silane moiety, with Z 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 x (OH) y R 5 z . The resulting film forming flame retardant is contemplated.
