    Abstract: A method of rapidly compounding melt forming resin (such as polypropylene) mica, and heat sensitive additives, such as chlorinated waxes, which comprises providing a molten mass of the resin, introducing the mica and heat sensitive additive into the molten resin and kneading the so introduced mica and additive to provide admixture thereof. The compounding is rapid and at optimal temperature.

    Abstract: A flash resistant epoxy encapsulating composition and its process of manufacture. The composition comprises a blend of from about 15 to about 80 weight percent epoxy resin, from about 9 to about 82 weight percent filler, from about 0.01 to about 2 percent catalyst by weight of resin, from about 10 to about 50 percent hardener by weight of resin, from about 3 to about 12 percent flash retardant by combined weight of resin and hardener and up to about 1.5 weight percent lubricant. The cured blend physically consists essentially of particles intimately and entirely embedded in a matrix. The process comprises blending the components of the above blend followed by milling the resulting blend between the rolls of a differential roll mill equipped with plows where the rolls have different surface temperatures, the hotter of the rolls being near the melting temperature of the resin.

    Abstract: A process for the production of synthetic linear polymers which contain atives is described, in which the polymer and the additives, both in the fluid state, are mixed, the resulting mixture is homogenized, and the homogenized mixture is in part conveyed to apparatus which uses it to make a product and in part is recycled, the recycled amount being preferably at least 5% of the total weight of the mixture. The preferred polymers are polyamides. The additives may be of any kind, e.g. antistatics, and they may be added as such or as a master batch consisting of a polymeric base containing finely particulated solid materials such as carbon black, matting agents or pigments. An apparatus for carrying out the process is also described, which comprises means for mixing fluid polymer with fluid additive, means for homogenizing the stream of the resulting mixture flowing through the apparatus, and means for recycling part of the homogenized stream to a zone of the apparatus upstream of the homogenizing means and for conveying the remaining part to an apparatus for subsequent processing. Static mixters may be used to homogenize the aforesaid mixture. The amount of the mixture that is recycled may be varied by suitable means such as a variable delivery pump. A particular preferred device for mixing polymer with additive is also described, which comprises valve means for preventing the polymer from backing up into the additive feed conduit.

    Abstract: To provide a resin composition, from which a molded body excellent in mechanical properties and having high elasticity, can be obtained, and the molded body obtained from such a resin composition. A resin composition comprising a melt-moldable fluororesin and inorganic fibers, wherein the ratio of the fluororesin to the sum of the fluororesin and the inorganic fibers is from 60 to 95 mass %, the inorganic fibers are inorganic fibers, of which at least a portion of the surface is treated with a sizing agent, and the mass loss ratio after heating the inorganic fibers at 400° C. for 60 minutes, is at most 3%; a method for producing the resin composition; and a molded body formed from the resin composition.
