Abstract
New glass fibers having an average length of about 100 to 400 &mgr;m and an apparent density of about 1 to 0.2 g/cm,are produced by spinning glass fibers, comprising spinning glass fibers into bundles, cooling with liquid to form wet bundles, directly cutting such bundles in the wet state, without previous drying, grinding said bundles to milled glass fibers in a high-efficiency mixer with the addition of a liquid, and then drying. The fibers are especially suited for filling polyurethanes by the PUR-RIM process.
