Abstract: The invention relates to a thermal insulation product based on mineral wool comprising mineral fibers, the product comprising two main faces and longitudinal and transverse edges perpendicular to the main faces, the product being characterized by the following orientation fractions: a longitudinal orientation fraction greater than or equal to 48 %, or even 50 %, along an angle of more or less 6° with respect to the plane of the main faces, when the mineral fibers are counted only in a longitudinal cross-section, and a mean orientation fraction greater than or equal to 40 %, or even 45 %, along an angle of more or less 6° with respect to the plane of the main faces, when the mineral fibers are counted both in a transverse cross-section and in a longitudinal cross-section. The invention allows the insulating power of a thermal insulation product based on mineral wool to be improved without increasing its thickness.

Abstract: A composite forming material of the present invention in which a fiberglass and a thermoplastic resin are compounded, where the fiberglass is a glass wool and a surface treatment is performed on the glass wool by spraying a solution which includes a silane coupling agent and/or a film former, a weight percent of the silane coupling agent to the glass wool is 0.24 wt %, and a weight percent of the film former to the glass wool is 2.4 wt %, the mean length of the glass wool is 600 ?m, and the diameter is 3.4 ?m.

Abstract: A device for manufacturing inorganic fibers by internal centrifugal spinning including: a centrifugal spinner configured to form inorganic fibers by fiberizing from molten inorganic material and at least one ring configured to spray water onto the inorganic fibers being formed. The device makes it possible to manufacture dry inorganic fibers thereby making energy savings.
