event preview | Compounding World Congress 2015
The speaker line up for the fi rst day of the Compounding World Congress 2015 includes (from top to bottom): Dr Oliver Frey; Dr Jörg Ulrich Zilles; Eira Kärjä; Frank Lechner; and Michael Thummert
sessions at

the conference, which will be chaired by Andy Beevers, the publisher and editor of Compounding World magazine.
Conductive compounds The opening session on the fi nal day will focus on technologies for adding electrical and thermal conductivity to plastics. Compounding World’s regular articles on such technologies always attract high levels of interest, and the conference sessions on these themes at our two Compounding World Forums in the USA have proved very popular. Dr Oliver Frey, head of the compound- ing department at Ensinger, will open the session with a presentation on thermally conductive compounds, focusing on the development of customised solutions for new applications. The German compounder has been working with a variety of thermally conductive additives in recent years, developing compounds based on high performance polymers, such as PEEK. Dr Frey will discuss the progress his company has been making in this fi eld.
Dr Jörg Ulrich Zilles, head of R&D at HPF The Mineral Engineers, a division of Quarzwerke based in Germany, will then discuss a new fi ller concept for increasing the thermal conductivity of thermoplas- tics. The company’s Silatherm mineral- based additive has been shown to increase the thermal conductivity of polymers, such as polyamide, while maintaining their good electrical insulation properties. Dr Zilles will show how the resulting thermally conductive compounds can be used to effi ciently dissipate heat and improve the reliability of electronic devices with high energy densities.
Eira Kärjä, marketing director at the
Finnish compounder Premix, will conclude the conductive compounds session with a presentation on electrical conductivity. She will focus on static dissipa- tive carbon black compounds, discussing the technical challenges, applications and standards associated with such materials.
Premix is a leading specialist in electrically conduc- tive plastics for electrostatic discharge (ESD), explosive

atmospheres (ATEX) and metal replacement applications in markets such as the
automotive, chemicals, electronics, medical and mining industries. The company has been active in this fi eld since 1983, so has considerable expertise in the development, production and application of such compounds.
Making the most of compounding lines
The next session of the Compounding World Congress will feature presentations from three of Germany’s leading suppliers of twin-screw extruders for compounding lines. We have asked the companies to give practical talks on how to get the most from compounding plants.
Frank Lechner, head of process technol- ogy at Coperion, will start the session with a paper focusing on the compounding of highly fi lled polymers using co-rotating twin-screw extruders.
There are growing demands for com- pounders to produce materials with increasingly high loadings of fi llers. Such requirements present signifi cant processing challenges, particularly when dealing with hard-to-handle fi llers. Lechner will provide practical advice on how to cope with these challenges, drawing on Coperion’s develop- ment work and its considerable experience in supplying and commissioning compounding lines and materials handling systems. Michael Thummert, head of corporate communications at Leistritz in Germany, will then give a talk on troubleshooting the twin-screw extrusion process.
This will cover practical solutions for
identifying and solving problems that can be encountered when operating such machin- ery. The presentation will draw on Leistritz’s extensive knowledge of developing,
manufacturing, testing and commissioning compounding lines, and then supporting
customers with their optimisation and maintenance. The session will be concluded by Thomas Winkel-
mann, head of development for plastics technology at KraussMaffei Berstorff. His presentation will focus on system engineering and the global rise of turn-key compounding lines. As we have reported in Compounding World, demand for turn-key systems is not only increasing in emerging
