The German company Wickert Maschinenbau GmbH has developed a coil station for rubber with an integrated load cell and automatic weight adjustment. The system allows for separating the roll material from the release film without any elongation and cutting it precisely. At a deviation of over ±1 g, the cutting length is automatically adjusted. In clean rooms compliant with ISO class 8, the peripheral component may also be used.

Plastics behave dependent on temperature and strain rate. When designing components, it is therefore important to know the behaviour of the plastic used, not only under laboratory conditions, but also under the subsequent conditions of use. The entire spectrum of possible temperatures must be considered. To this end, scientists at the Fraunhofer Institute for Structural Durability and System Reliability LBF have expanded the dynamic possibilities at the institute's own modified high-speed testing machine with a device that enables plastics to be examined even at low temperatures – validated down to -40 °C-– without a thermal chamber.

The German company Gummiwerk Kraiburg GmbH & Co. KG has developed an elastomer-based solution to protect the leading edges of wind turbine rotor blades. According to the company, during their operations, the rotor blades are exposed to enormous loads. The leading edges of the blades, in particular, are subjected to a disproportionate degree of stress from raindrops and other particles.

There are numerous methods to measure filler dispersion in rubber compounds. Kylie Knipp from Akron Rubber Development Laboratory has compared three of them in the current issue of RFP Rubber Fibres Platics 02 2020: Phillips Dispersion test, Dispergrader test, and nSpec 3D topography scan. A simple SBR compound was selected and five different fillers were evaluated. The paper will briefly discuss the advantages and disadvantages of the three different dispersion measurement techniques.

For some months now, KraussMaffei’s R&D centre at the Hanover site has been equipped with an advanced industrial-scale recompounding system. With the new system KraussMaffei substantially extends its capacities for customer trials and its own testing activities associated with recycling and recompounding processes. Interested customers can carry out industrial-scale trials on the new EdelweissCompounding line in at the R&D centre. The line is composed of two ZE 65 BluePower twin-screw extruders and designed for a maximum output rate of 2,000 kg/h. The combination of two twin-screw extruders enables high degassing capacities, efficient odour removal, ideal dispersive and dispersing mixing effect, gentle melt treatment at a high throughput rate, the company says.
