A system that provides for simultaneous thermal regulation of both components of a two-component system, while maintaining their separation prior to introduction into a conventional static mixer element, in order to assure that the mixed fluid, when dispensed, is at the optimal temperature and viscosity. The thermal capacity can be adjusted by altering the configuration to increase or decrease the thermal transfer area as required for each specific application.

Method and system for manufacturing bulked continuous filament having tonal coloring from PET comprising: an extruder (202); a static mixing assembly (208) coupled to the extruder and comprising a housing and one or more individual static mixing elements disposed within the housing; the method and system further comprising a plurality of colorant ports along a length of the static mixing assembly such that each of the plurality of colorant ports is configured to provide colorant (204) to a polymer stream at a different location along the length of the static mixing assembly, and one or more spinning machines (212) positioned downstream of the static mixing assembly and coupled to the static mixing assembly to receive the colored polymer stream. The spinning machine(s) may be configured to form the colored polymer stream into bulked continuous carpet filament having a tonal color effect.

An installation for manufacturing cross-linkable polyethylene compounds which comprises a melting machine (101), a melt pump (102) and a filtration unit (103) to produce cross-linkable polyethylene compounds that may be further used for manufacturing insulating parts of medium, high and extra-high voltage power cables, and a method for manufacturing such cross-linkable polyethylene compounds.

The invention relates to continuous methods for compounding and applying adhesives, characterized in that (i) a base component of the adhesive is mixed continuously with at least one aggregate so as to produce a compounded adhesive; and (ii) the adhesive compounded in this manner is applied to a substrate. The invention also relates to such methods where a device as described here is used to carry out the method.

An application device for paste-like and/or flowable material, including a housing with a feed region for material and at least one discharge region for material. At least one mixing region is formed between the feed region for material and the discharge region for material and the at least one mixing region is designed as at least one mixing device.

Dispensing system for dispensing a mixture of a first component and a second component, the dispensing system comprising: (i) a dispensing gun comprising an inlet body with a first passage for feeding in the first component under pressure and a second passage for feeding in the second component under pressure, the first and second passages respectively comprising a closable first outlet and a closable second outlet, which may be operable by means of a handle or trigger of the dispensing gun; (ii) a static mixing nozzle, detachably connectable to the outlets of the body and provided for mixing and dispensing the components, the static mixing nozzle comprising a first section containing a first chamber and a second chamber for conducting the first and second component respectively and a second section, subsequent to the first section (in forwards flow direction), containing a mixing chamber with static mixing elements which promote mixing the first and second components and conducting the mixture to a nozzle tip serving as an outlet for the mixture. According to the invention, at least one of the first and second chambers of the static mixing nozzle contains a series of static backflow prevention elements, arranged for hindering backflow of the respective component within the respective chamber.

The invention relates to a process for the production of thermoplastic moulding compounds, in particular for the production of acrylonitrile-butadiene-styrene (ABS), wherein at least a first reagent (11) and a second reagent (12) of the thermoplastic moulding compounds are fed to a loop conduit (29) which comprises a static mixer (36), wherein the reagents (11, 12) are pressed in loops through the loop conduit (29) and passing the static mixer (36), whereby the reagents (11, 12) are dispersed to form a dispersion (15) in the static mixer (36). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

A process and device continuously prepare a filled rubber masterbatch. The process comprises bringing into contact, in a mixing zone, a first liquid-phase flow and a second liquid-phase flow, the first flow being an elastomer emulsion, the second flow being an aqueous suspension of filler particles, such that one of the two flows emerges inside the other flow and that the two flows are transported at low pressure before they are brought into contact.

A device for reducing the microbiological contaminants of container products made predominantly of plastics materials feeds a plastics granulate to an extruder assembly (19) that melts the granulate. The granulate is subsequently supplied to a form-fill-seal machine for producing a container product. A guide assembly (35) guides the plasticated plastic material from the extruder assembly (19) to the machine. At least one guide assembly (35) has at least one flow or channel guide (41) for the melted plastics material, so that microbiological contaminants are guided predominantly into the interior of the wall of the polymeric tube that interior is enclosed by regions of the plastic material that are less contaminated.
