Elongate, deformable, composite tubing for use in maintaining or controlling the temperature of a fluid conveyed therethrough comprising one or more tubular fluid conveyance lines or one or more tubular fluid conveyance lines disposed in heat transfer relationship with one or more heating lines and having disposed in encompassing relationship thereabout an improved flexible thermal barrier. The improved thermal barrier comprises one or more flexible, flame resistant, low chlorine bearing, sheet-like layers of low bulk fibrous glass elements having a density of less than about 20 lb./cu. ft. providing improved thermal insulation characteristics in combination with improved flexibility and reduced outer diameter.

Composite tubing product

A synthetic resinous tube having a plurality of bonded coaxial layers with at least one layer being thermoplastic and another substantially non-thermoplastic is formed by the simultaneous coaxial extrusion of thermoplastic tubes and electron irradiation of one of the layers of the tube to convert it from a thermoplastic resin.

Synthetic resinous tube

An electrical conductor insulated with a cured heat resistant, radiation resistant, substantially dimensionally stable electrical insulation comprising a chlorinated polyethylene elastomer composition which has been electron cured with a dosage of at least 1 megarad. The product of the invention may be a single insulated wire or a group of twisted or cabled insulated wires enclosed in an electron cured chlorinated polyethylene elastomer composition jacket.

Wire and cable

An electrically insulated conductor adapted to be used at high temperatures in power plants, refineries and chemical process plants for connecting instruments has at least one pair of electrical conductors insulated with an irradiation cured ethylene-tetrafluoroethylene copolymer, ethylene-chlorotrifluoroethylene copolymer or polyvinyl chloride polymer and a drain wire enclosed in a metallic shield and an irradiation cured halosulfonated polyethylene, polychloroprene or chlorinated polyethylene jacket.

Electric conductor adapted for use in process instrumentation

The present invention relates to methods for processing curable thermoplastic elastomers and particularly to flexible, shaped articles made therefrom which have improved high strength, radiation and temperature resistance and electrical characteristics useful as fluid transmission tubing and/or as electrical insulation. Such articles are made from uncured, thermoplastic elastomer materials -- in the form of selectively hard, radiation sensitive, flowable solids -- which are thermoplastically molded to provide an essentially uncured, dimensionally stable, intermediate shaped article. Such intermediate articles are radiation-cured to provide finished cross-linked articles having such characteristics.
