Twin-screw extruder specialises in
compounding
Supporting a freely selectable sequence of feeding, mixing and shearing elements, Polymer-Chemie's segmented twin screw allows screw configurations to be matched exactly to the processing task.
The R and D centre of Polymer-Chemie at Bad Sobernheim in Germany has received a twin-screw extruder with peripheral technology geared towards compounding tasks The new co-rotational compounding unit supplements a line-up of diverse mixers, rolling systems and counter-rotational extruders at the Sobernheim facility used by Polymer-Chemie's PVC Compounds Division to develop tailor-made material compositions to customer specifications

PVC retains antistatic properties
Unlike plastics with an antistatic finish, Polymer-Chemie's permanently antistatic compounds do not even require particular ambient conditions to retain their effect.
Re-inforced PVC boosts strength and stiffness
The new material's increased strength and stiffness will usually permit a reduction in wall thickness while keeping product characteristics unchanged.
Structured analyses and tests, conducted in the attached material testing laboratory, provide near-real-time quantitative data on how closely each new recipe meets requirements.
Extensive resources for instrument-based analytics enable the laboratory to carry out structural investigations, thermal, optical and rheological measurements, evaluations of industrial processing characteristics and testing of mechanical properties, up to and including accelerated ageing tests.
Polymer-Chemie rapidly completes numerous custom development projects each year.

The PVC experts' full-service range comprises consulting, process cost optimisation and project management modules, even where the process chain involves multistage or trans-national interfacing.
For example, recent developments include compounds for producing sealing profiles with a long-term weather resistance for use on exterior building fronts and even compounds with a transparent matrix and distinctive olfactory properties for decorative or technical applications.
The new extruder system installed at the research and development centre offers plenty of flexibility to address changing objectives.
Supporting a freely selectable sequence of feeding, mixing and shearing elements, the segmented twin screw allows screw configurations to be matched exactly to the processing task.
In combination with a discharge extruder flanged to the twin-screw unit and a die-face pelletiser (dry type), the machine forms a complete extrusion line, which is capable of delivering samples of newly developed material to the customer in sufficient quantities for trials.
The Business Unit PVC Compounds of Polymer-Chemie develops, produces and markets - under the trade name SorVyl - both unplasticised PVC compounds and plasticised PVC compounds.
Its fifteen production lines together have a compounding capacity of around 70,000 tonnes/year.
These compounds enjoy application in numerous branches of industry, from the building and automotive industries through to the electrical engineering and household appliance industries.
