摘要： An insulation product is disclosed that includes a plurality of glass fibers and a cross-linked formaldehyde-free binder composition at least partially coating the glass fibers. The glass fibers have an average fiber diameter in the range of 8 HT (2.03 μm) to 15 HT (3.81 μm). The insulation product is structured such that at least 30% by weight of the glass fibers in the insulation product are oriented within +/−15° of a common plane defined by a length and width of the insulation product. The insulation product has a density, when uncompressed, between 0.2 pcf and 1.6 pcf.

摘要： An insulation product is disclosed comprising a plurality of glass fibers; and a cross-linked formaldehyde-free binder composition at least partially coating the glass fibers. The glass fibers have an average fiber diameter in the range of 8 HT (2.03 μm) to 15 HT (3.81 μm). At a density (x) between 0.3 pcf and 1.6 pcf, the insulation product may achieve a thermal conductivity (y) less than or equal to that which satisfies Formula (III): y=0.116x2−0.3002x+0.4219.

摘要： A device for texturizing strand material into a wool-type product includes outer and inner nozzle sections. The outer and inner nozzle sections interface and define a passage through which the strand material travels. At least a portion of the passage has a non-uniform diameter that increases in a direction moving away from an input end of the device.
