A method for producing hollow fine particles containing a fluorine-containing resin and having a large average particle size. The method includes a step A of providing hollow fine particles by dispersing a solution containing a fluorine-containing monomer, an oil-soluble initiator, and a non-polymerizable solvent in water containing a fluorine-containing surfactant and thereby polymerizing the fluorine-containing monomer. Also disclosed are hollow fine particles including a fluorine-containing resin and having an average particle size of 70 nm or greater and 10 μm or smaller. The hollow fine particles each have a porosity of 5% by volume or higher, and the fluorine-containing resin contains a polymerized unit based on a fluorine-containing monomer and a polymerized unit based on a crosslinkable monomer.

The present invention aims to provide a resin composition capable of providing a molded article that has high slidability and high impact resistance, as well as excellent tensile strength. The present invention relates to a resin composition containing an aromatic polyether ketone resin (I) and a fluororesin (II). The composition preferably has a sodium content of 120 ppm or less relative to the composition or a calcium content of 15 ppm or less relative to the composition.

The invention pertains to composition of fluoroplastic and poly(aryletherketone), to method of making the same, and to shaped products therefrom, including notably wire sheaths, which combine advantageous performances of both ingredients, which can be easily manufactured through conventional equipment's, and which notably deliver room temperature toughness, in combination with notably chemical resistance and dielectric properties of fluoroplastics and with mechanical performances of poly(aryl ether ketone)s.

A conductor assembly including an electrically conductive material defining a longitudinal axis, a microporous membrane surrounding the electrically conductive material defining a series of pores, and a ceramic material within at least a first portion of the series of pores.

A fluororesin cable can include an electric wire having a central conductor covered with an insulator, an inclusion, a tape made of a resin, and a sheath made of a fluororesin. The inclusion is arranged along the electric wire. The tape is wound around an outer periphery of an aggregate of the electric wire and the inclusion. The sheath entirely covers the aggregate and the tape. Here, a material for the inclusion is harder than a fluororesin material constituting the sheath.

The present invention relates to a process for synthesizing carbon nanotubes by continuous chemical vapor deposition at the surface of reinforcements, said reinforcements constituting a mixture A (i) of particles and/or fibers of a material comprising at least one oxygen atom and (ii) of particles and/or fibers of a material chosen from carbides and/or of a material comprising at least one silicon atom, said process comprising the following steps, carried out under a stream of inert gas(es) optionally as a mixture with hydrogen: (i) heating of said mixture of reinforcements A in a reaction chamber at a temperature ranging from 400° C. to 900° C.; (ii) introducing into said chamber a source of carbon consisting of acetylene and/or xylene, and a catalyst comprising ferrocene; (iii) exposing said heated mixture A to the source of carbon and to the catalyst comprising ferrocene for a sufficient time to obtain carbon nanotubes at the surface of the reinforcements constituting said mixture A; (iv) recovering a mixture B at the end of step (iii), optionally after a cooling step, said mixture B consisting of the mixture (A) of reinforcements comprising carbon nanotubes at their surface; (v) optionally, separation (a) of the particles and/or fibers of a material comprising at least one oxygen atom, (b) of the particles and/or fibers of a material chosen from carbides and/or of a material comprising at least one silicon atom.

The process of foaming a polyolefin, e.g., polyethylene, composition using as a nucleator a combination an azodicarbonamide (ADCA) and a fluororesin at a ADCA: fluororesin weight ratio of 60:40 to 20:80. The synergic effect between these two nucleating agents results in a higher nuclei density and a foamed product with a smaller cell size as compared to processes using and products produced by the use of neat PTFE or neat ADCA alone as the nucleating agent.

A production method comprising: (a) a step of melt-mixing a base resin containing a chlorinated polyethylene; an organic peroxide, an inorganic filler, and a silane coupling agent, in specific ratios, at a temperature equal to or higher than a decomposition temperature of the organic peroxide, to prepare a silane master batch; (b) a step of mixing the silane master batch obtained in the step (a) with a silanol condensation catalyst, and then forming the resultant mixture; and conducting at least one of the melt-mixing in the step (a) and the mixing in the step (b) is performed in the coexistence of a chloroprene rubber or a polyvinyl chloride; a heat-resistant chlorine-containing crosslinked resin formed body produced by the method, a silane master batch, a mixture and formed body thereof, and a heat-resistant product.

The present invention generally relates to deformable polymer composites, and more particularly to, deformable polymer composites with controlled electrical performance during deformation through tailored strain-dependent conductive filler contact. According to embodiments, a deformable elastomeric conductive material includes: an elastomeric polymer matrix; and conductive filler material uniformly dispersed in the elastomeric polymer matrix sufficient to render the material electrically or thermally conductive. The conductive filler material comprises a plurality of substantially non-entangled particles having an aspect ratio sufficiently large to enable the particles to substantially remain in contact and/or in close proximity with adjacent particles so as to maintain conductive pathways in the material when the material is subjected to deformation up to and exceeding 10% strain.

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
