A method of forming a polyethylene terephthalate (PET) mixture with talc includes: providing a feed of PET (PET feed); providing a feed of talc (talc feed); mixing the feed of PET with the feed of talc in a mixer at a PET:talc ratio of about 3:1 to about 1:3 to form a PET/talc mixture; and providing the PET/talc mixture as output. A method of forming a Polyethylene Terephthalate (PET) alloy having talc includes: providing a feed of the PET/talc mixture (PET/talc feed); providing a feed of PET (PET feed); mixing the feed of PET with the feed of PET/talc in a mixer to form a PET alloy having from about 1% (w/w) talc to about 50% talc (w/w); and providing the PET alloy as output.

The module (19) for a conveyor system for bulk goods has at least one first tubular section (20). A second tubular section (23), which is provided with at least one coupling piece (21), branches away from said first tubular section. The second tubular section (23) adjoins a valve (13) which has three connections (25, 26). The first connection forms a flow-connection with the second tubular section (23). The second connection (26) of the valve (13) can be selectively connected to the first connection (25) by means of a first line and to the third connection (25) by means of a second line (48).

Method for the manufacture of a colored polymer composition comprising a polymer, a release agent and a colorant, the method comprising the steps of feeding a solid form of a release agent composition comprising said release agent and said colorant to a feed section of a melt mixing device, feeding said polymer to said melt mixing device and mixing said release agent composition and said polymer in said melt mixing device at a temperature above the melting temperature of said polymer, whereinsaid colorant is a pigment, or a dye which is soluble in said release agent, said polymer comprises or consists of polycarbonate, the release agent is selected from the group consisting of penta-erythritol tetra stearate, glycerol monostearate, glycerol tristearate and mixtures thereof.

This disclosure relates to a novel type of high molecular weight polyethylene composition, and product made from said composition, with industrially useful properties, and the process of making said composition and product.

The invention is a weigh ng and mixing system for the preparation of mixtures of components required by processing machines for the manufacture of plastic products. In particular the invention is suitable for the preparation of weighed mixtures comprised of at least two different masterbatches in order to obtain the color shade desired for a specific plastic product.

This invention is to improve the reaction efficiency of a peroxide introduced into a cylinder compared with conventional art. In the peroxide reaction method and peroxide reaction device using an extruder according to this invention, in which a peroxide and a raw material such as a synthetic resin, a natural resin, and an elastomer are introduced into a cylinder of the extruder, wherein the raw material and the peroxide are reacted with each other in the cylinder, the raw material is introduced from a raw material supply hopper, the peroxide is introduced from a downstream side of the raw material supply hopper, and the temperature of the raw material in a peroxide introduction portion is adjusted to a temperature lower than the one-minute half-life temperature of the peroxide.

Provided is an automatic continuous weighing/raw material supply system of a flooring tile manufacturing apparatus, and more particularly to an automatic continuous weighing/raw material supply system of a flooring tile manufacturing apparatus, which can stably supply a raw material to the flooring tile manufacturing apparatus.

The invention is a weighing and mixing system for the preparation of mixtures of components required by processing machines for the manufacture of plastic products.

A method for producing a sealant includes a weighing and mixing step, a kneading step, a stirring and defoaming step, and a filling step. In the weighing and mixing step, a main component and a curing agent are weighed and mixed together. In the kneading step, the mixture mixed in the weighing and mixing step is kneaded. In the stirring and defoaming step, the kneaded product kneaded in the kneading step is stirred and defoamed. In the filling step, the kneaded product defoamed in the stirring and defoaming step is filled into a container. In the stirring and defoaming step, the kneaded product is stirred under a condition wherein a stirring rotational speed at which the kneaded product is stirred and a stirring time for which the kneaded product is stirred are within a range from a product lower limit value to a product upper limit value.

In the field of tire production, the invention relates to methods and systems for creating unvulcanized rubber batches prior to mixing them in a rubber mixer, including selecting at least one batch for mixing in the mixer, wherein each batch corresponds to a selection of rubber bales (A.sub.I, B.sub.I, C.sub.I) each corresponding to a rubber nature (A, B, C) having predefined characteristics, in order to obtain a proportion corresponding to a predetermined proportion, a target weight to attain a difference between (a) the required weight of the batch and (b) the sum of the weight of the bales (A.sub.I, B.sub.I, C.sub.I) and the weight of the pieces (A.sub.IJ, B.sub.IJ, C.sub.IJ).
