Title (EN) PROCESS FOR FOAMING POLYOLEFIN COMPOSITIONS USING AN AZODICARBONAMIDE/CITRATE MIXTURE AS A NUCLEATING AGENT
(FR) PROCÉDÉ DE MOUSSAGE DE COMPOSITIONS DE POLYOLÉFINE À L'AIDE D'UN MÉLANGE D'AZODICARBONAMIDE/CITRATE UTILISÉ EN TANT QU'AGENT DE NUCLÉATION
Abstract:
(EN) A process of foaming a polyolefin, e.g., polyethylene, composition using as a nucleator a combination of (A) azodicarbonamide, and (B) a mixture of (1) a first component consisting of at least one of citric acid and an alkali metal citrate, and (2) a second component consisting of at least one of an alkali metal citrate, a di-alkali metal hydrogen citrate, an alkali metal dihydrogen citrate and an alkali metal bicarbonate, with the proviso that the mixture is not solely composed of alkali metal citrate.
(FR) La présente invention concerne un procédé de moussage d'une composition de polyoléfine, par exemple, de polyéthylène, faisant intervenir, en tant qu'agent de nucléation, une combinaison constituée (A) d'azodicarbonamide, et (B) d'un mélange de (1) un premier constituant constitué d'acide citrique et/ou d'un citrate de métal alcalin, et de (2) un second constituant constitué d'un citrate de métal alcalin, et/ou d'un hydrogénocitrate de métal di-alcalin, et/ou d'un dihydrogénocitrate de métal alcalin et d'un bicarbonate de métal alcalin, à condition que le mélange ne soit pas uniquement constitué d'un citrate de métal alcalin.
