Abstract:
The present invention provides a novel filament coating process. Useful filaments include high strength, reinforcing fiber such as fiberglass. By the process, a filament bundle is transversely spread and individual filaments are coated. In a particular application, pultruded rod may be advantageously made from the coated filament.
Abstract:
Antifriction compositions useful for bearings comprising poly(arylene sulfide), a solid lubricating component, a reinforcing material, and a filler in which the commonly employed antimony trioxide filler is replaced in whole or in part by a replacement filler of calcium carbonate, titanium dioxide, barium sulfate, hydrated aluminum silicates, red iron oxide, carbon black or diatomaceous earth, compatible with the other components.
Abstract:
An improved welding rod for joining plastic materials is provided. The welding rod includes a core of electrically resistive fiber, and a winding of electrically resistive fiber separated by a plastic barrier layer. Also provided is a method for joining plastic materials using the welding rod.
Abstract:
A foamable composition useful for rotational molding, is provided. The composition advantageously includes an ethylene vinyl ester copolymer as an additive. The additive beneficially has a higher melt index than the base resin of the composition.
Abstract:
Resinous pigment concentrates comprising at least one pigment and a dispersing additive of a naphthenic extender oil and/or a phosphate ester blended with a major portion of a resinous polymer containing a significant proportion of at least one polymerized conjugated diene monomer, when used for coloring resinous polymers as described, are effective in reducing such defects in finished articles as gels and surface blemishes.
Abstract:
A method for improving the flexular modulus and/or impact strength of a polymer of olefin by admixing therewith a mica and at least one of talc or clay. A filled composition provided thereby.
Abstract:
A method for improving processability of compositions of normally solid polymers of arylene sulfide by the addition of an amount of solid ethylene polymer effective to improve the processability of the composition. A composition of matter of normally solid poly(arylene sulfide) and an amount of solid ethylene polymer effective to improve processability of the composition. In a preferred embodiment the amount of solid ethylene polymer in the total composition is in the range of about 0.1 to about 5 weight percent.
Abstract:
In one aspect, the present invention provides a load-bearing structure with a novel interlocking edge. Also provided is a method of making a load-bearing structure having an overlapping edge, in which structural members are combined so that a stepped-down lip of one structural member covers a peripheral edge of another member. Also provided is a load-bearing structure having cellular structure and which is useful with or without an overlapping edge. In addition, there is provided a molding method for making cellular, load-bearing structures.
