Provided is a fiberglass binder composition which comprises a polycarboxy polymer, polyol and an imidazoline. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus-containing organic acid. The resultant binder provides minimal processing difficulties and a product which exhibits minimal water absorption.

A type of (and method of making) fiberglass insulation is disclosed. Such insulation comprises: glass fibers; a polyacrylic glycerol (PAG) binder coating said glass fibers; and at least one of a coloring agent and a biocide adhered to said PAG binder. Such fiberglass insulation can take the form of a batt, board (a heated and compressed batt) or molding media (a different form of heated and compressed batt). The coloring agent and/or the biocide can be applied where the batt (or board or molding...

Glass fibers prepared by flame attenuation display excellent chemical resistance to both acids and moisture while being highly biosoluble at the same time. The glass compositions are characterized by ratios of components which are reflective of acid resistance, biosolubility, and moisture resistance. Preferred glass fibers exhibit a biodissolution greater than about 350 ng/cm/.sup.2 hr.

A fiberglass railcar roof that includes a fiberglass surface with a central portion and a peripheral portion adapted to be joined to the upper edge region of a railcar. In some embodiments, the roof includes plural elongate fiberglass ribs extending transverse to the longitudinal axis of the fiberglass surface. In some embodiments, the roof is adapted for use on refrigerated, high cube and cryogenic railcars. Methods for forming the invented roofs and roof panels are also disclosed.

A tunable fiberglass whip antenna comprises an elongated fiberglass core having a conductive wire coiled around the core and serving as the antenna. The uppermost extremity of the wire is tightly coiled around an axial bore within the fiberglass. A metal insert, fixed within the fiberglass bore is in threaded engagement with a set screw accessible from the top of the antenna. By adjusting the longitudinal position of the set screw relative to the tightly wound wire at the end of the antenna, the...

A seismic float is made in two parts--an upper foam-filled fiberglass hull and a lower steel hull, thereby resulting in a more stable float of reduced dimensions.

This invention is directed to an improved process for making fiber reinforced articles comprising the steps of (a) applying a preformed plastic shell having the configuration of the desired article to a holding fixture therefore having sealing means at the peripheral edges thereof; (b) applying to the surface of the shell fibrous reinforcement material; (c) introducing to the reinforcement material a liquid plastic resin mixture; (d) applying to the surface of the resin mixture-containing reinfo...

A frangible fiberglass insulation batt includes a pair of fiberglass strips arranged to lie in side-by-side relation to one another and a frangible polymerized binder bridge spanning a gap between the fiberglass strips and retaining the fiberglass strips in side-by-side relation. To produce such a batt, a stream of uncured fiberglass insulation is cut along its length to form two side-by-side fiberglass strips and then passed through a curing oven to cause heat generated in the oven to polymeriz...

A cable wrap fabric for protecting a communications cable is woven of fiberglass yarns plied with or without low melt thermoplastic yarns, and water swellable superabsorbent yarns. The water swellable superabsorbent yarns are interspersed at spaced intervals within the fiberglass yarns. The fiberglass yarns dissipate heat energy created by lightning strikes or excessive thermal shocks. The superabsorbent water swellable yarns block the progression of water through the cable. The low melt thermop...

A frangible fiberglass insulation batt includes a pair of fiberglass strips arranged to lie in side-by-side relation to one another and a frangible adhesive bridge spanning a gap between the fiberglass strips and retaining the fiberglass strips in side-by-side relation. To produce such a batt, a fiberglass insulation blanket is cut along its length to form two side-by-side fiberglass strips and then an adhesive material is applied to form a frangible adhesive bridge between the strips.
