An improved coating is provided for fiberglass insulation articles which is coated onto the fiberglass insulation, thereby providing the fiberglass insulation with good mechanical properties and other desirable properties such as low emission of volatiles, fire retardency, low potential smoke generation and low air friction.

A glass fiber wallcovering is made by sequential application of hydrophilic and hydrophobic agents to selectively create an image for painted effects.

A mudmat assembly for supporting a portion of a subsea offshore platform on a soft, unconsolidated underwater surface is described. The mudmat assembly includes at least one fiberglass plank, a mudline framing plane that is attached to and provides support for the fiberglass plank, and integral framing beams attached to and providing support for the fiberglass plank. The fiberglass mudmat assembly of the present invention requires minimal cathodic protection, has a high flexural strength, and is...

An improved composite fiber of fiberglass and polytetrafluoroethylene (PTFE) is provided. The composite fiber comprises a coherent strand of commingled filaments of fiberglass and PTFE which is far more resistant to flex, abrasion, and chemical attack than previous fiberglass fibers. Preferably filaments of expanded PTFE tow yarn and filaments of PTFE are combined through a process of air-jet texturing. The fibers of the present invention have a wide range of possible uses, including being forme...

A roofing system that provides a safe, long lasting, leak-free and maintenance-free insulated roof for flat roof applications. More particularly, a sandwich panel comprises an inner foam core, a fiberglass skin fully encapsulating and surrounding the core, and a gel coating surrounding the skin. The panel has two substantially parallel surfaces and a peripheral edge having a step edge. A plurality of panels having two different shapes and relative dimensions are alternately secured to purlins to...

The vaulting pole has at least three layers, two of the layers comprising fiberglass tape helically wound along the pole into a succession of butt-jointed turns with the fibers thereof extending primarily lengthwise of the tape but the turns of the two layers being crossed with respect to each other, and the third layer comprising a plurality of turns of fiberglass cloth sandwiched between the two tape layers, the fibers of the cloth extending primarily lengthwise of the pole.

A suspended ceiling grid system has parallel main runners and perpendicular cross members which are formed of pultruded fiber-reinforced plastic. The main runners have vertical webs with regularly spaced vertical slots. The cross members are connected to each other and to the main runners by resilient extruded PVC cross connectors which pass through the main runner web slots and resiliently engage the ends of the cross members. The cross connectors have a horizontal element which is received wit...

A one-piece molded tennis racket or similar article constructed of resin-impregnated fabric consisting essentially of a plurality of substantially continuous fibers some of which extend from the butt of the handle, around the head frame and back down the handle, and other continuous fibers which extend just around the head frame. In one embodiment of the invention, the unique laminating technique provides a hollow tubular handle. In another embodiment of the invention, a flat handle is formed co...

A protective covering for a fiberglass boom is disclosed. The present invention is particularly useful on the fiberglass boom used on aerial lift trucks used by electrical utilities and for other similar applications. The covering includes a polyurethane coating applied to the surface of the fiberglass boom. Polyurethane strip material is spirally wrapped over the polyurethane coating and bound to the polyurethane coating by the use of a solvent sealer, preferably tetrahydrofuran. A second polyu...

Process and apparatus for recovering clean fiberglass and urea formaldehyde from urea formaldehyde treated waste fiberglass, which involves the use of a continuous batch tunnel machine comprising end to end modules in each of which a perforated basket is rotatable and of such construction as to transfer goods within each basket to subsequent baskets and out the end of the basket at the exit of the machine. The waste fiberglass is introduced into the basket at the entrance to the machine to pass ...
