A method of forming articles made of an inorganic fiber material using compression molding. In one respect, a method of forming an article, wherein the method includes providing a molding composition comprising inorganic fiber and an inorganic binder, and compression molding the molding composition into the article. In another respect, the method including providing a molding composition comprising inorganic fibers and binder, and compression molding the molding composition into the article, wherein at least 75% by weight of the molded article is inorganic material. In some embodiments the cured binder is capable of withstanding temperatures of at least (315 ~C) without significant degradation or deterioration due to heat. Articles made by the use of such methods and a molding composition for use in compression molding an article are also included.

L'invention concerne un procédé de formage d'articles en matériau à base de fibres inorganiques, par moulage par compression. Selon un aspect de celle-ci, l'invention concerne un procédé de production d'un article, qui consiste à prévoir une préparation de moulage comprenant des fibres inorganiques et un liant inorganique, et à mouler par compression ladite préparation, de sorte que l'article soit formé. Selon un autre aspect, l'invention concerne un procédé qui consiste à prévoir une préparation de moulage comprenant des fibres inorganiques et un liant et à mouler par compression ladite préparation, de manière que l'article soit formé, au moins 75 % en poids de l'article moulé étant constitué de matière inorganique. Dans certains modes de réalisation, le liant traité est capable de résister à des températures d'au moins 600 ·F sans dégradation ou détérioration due à la chaleur. Les articles fabriqués selon lesdits procédés et une préparation de moulage à utiliser dans le moulage par compression d'un article sont également décrits.
