A fire resistant or acoustical article comprising a bast fiber component, a thermoplastic material that acts as a binder, and a first fire retardant component, the article having a coating of a second fire retardant component, such that the article may be used in the manufacture of structures having a Class A fire rating. According to one method of manufacture, a fibrous mass including a bast fiber component and a thermoplastic binder is heated and compressed to a desired thickness and density, followed by the dispersal of the first fire retardant there through, and coated with the second fire retardant component.
La présente invention concerne un article ignifugeant ou acoustique comprenant un composant fibre libérienne, un matériau thermoplastique jouant le rôle de liant et un premier composant ignifugeant, l'article présentant un revêtement constitué d'un second composant ignifugeant, de sorte que l'article puisse être employé dans la fabrication de structures ignifugeantes de Classe A. Selon une méthode de fabrication, une masse fibreuse incluant un composant fibre libérienne et un liant thermoplastique est chauffée et comprimée jusqu'à l'épaisseur et la densité recherchées, puis le premier ignifugeant y est dispersé, et le mélange est revêtu du second composant ignifugeant.
