Title
(EN) CHEMICAL BLOWING AGENT AND THERMALLY EXPANDABLE THERMOPLASTIC COMPOSITION
(FR) AGENT D'EXPANSION CHIMIQUE ET COMPOSITION THERMOPLASTIQUE THERMOEXPANSIBLE
Abstract
(EN)
The present invention relates to a chemical blowing agent comprising at least one tertiary alkyl carbamate. The chemical blowing agent can be activated thermally and is suitable for foaming thermoplastic materials and can for example be incorporated into thermally expandable baffle and/or reinforcement elements which are used in automotive manufacturing and building insulation.
(FR)
La présente invention concerne un agent d'expansion chimique comprenant au moins un carbamate d'alkyle tertiaire. L'agent gonflant chimique peut être thermoactivé et est approprié au moussage de matériaux thermoplastiques et peut par exemple être incorporé dans des éléments de garniture ou de renforcement thermoexpansibles qui sont utilisés dans la construction automobile et l'isolation des bâtiments.
