BIOPOLYMERS
MATERIALS, PROPERTIES, SUSTAINABILITY
Within component production, the material factor represents the main aspect not only in terms of cost, but also in terms of energy. Therefore, the increase in sustainability must inevitably also lead via the use of materials. Establishing a circular economy is of course an option here, but it is not the solution for every company or product.
The use of bio-based and/or biodegradable polymers, possibly in combination with the circular economy, can be a solution in particular.
But what materials and raw material manufacturers are there? What properties do these materials have and to what extent can properties be adapted and where are the limits?
Enabling project participants to judge for themselves which materials can be used for their own products and whether they increase the sustainability of the product.

MULTI-COMPONENT TECHNOLOGY
NEW THOUGHT
Multicomponent technology is an important achievement that has been continuously perfected for decades, and even poorly adhering material combinations have been technically optimized to achieve the best possible bond. This simply ruled out or made it impossible to repair or change individual combinations, and a cycle for these products as well.
It won’t be long before there will be regulations on this that will make it difficult, if not impossible, for these very composite components to exist.
For this reason, we decided to tackle this project.
You can find all the information in the flyer.
Project start: January 2023
Duration: 2 years
Costs per company: 9 ,500 euros per year plus ges. VAT
Minimum number of participants: 10 companies
Project meetings: 2-3 times per year at the Kunststoff-Institut Lüdenscheid or at participants’ premises
Project content: 6 defined work packages, fine tuning is done in the project group at the kick-off meeting

WERKSTOFFE, EIGENSCHAFTEN, NACHHALTIGKEIT
Der Faktor Material stellt innerhalb der Bauteilproduktion nicht nur kostentechnisch, sondern auch energetisch den Hauptaspekt dar. Daher muss die Steigerung der Nachhaltigkeit zwangsweise auch über den Materialeinsatz führen. Die Etablierung einer Kreislaufwirtschaft ist hier natürlich eine Option, aber nicht für jedes Unternehmen oder Produkt die Lösung.
Der Einsatz von biobasierten und/oder biologisch abbaubaren Polymeren, ggf. in Kombination mit der Kreislaufwirtschaft, kann insbesondere eine Lösung darstellen.
Aber welche Materialien und Rohstoffhersteller gibt es? Welche Eigenschaften besitzen diese Werkstoffe und inwieweit lassen sich Eigenschaften anpassen und wo sind die Grenzen?
Die Projektteilnehmer in die Lage versetzt, selbst beurteilen zu können, welche Materialien für die eigenen Produkte eingesetzt werden können, und, ob diese die Nachhaltigkeit des Produktes erhöhen.

PVD COATING OF PLASTIC PARTS 3
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
The desire in the decorative field to apply a robust PVD coating directly to the plastic substrate or a PVD layer to a primer coating without a protective coating in order to save process costs, minimize scrap, obtain a better gloss image, be able to perfectly reproduce textured plastic surfaces or realize a precoating for electroplating is often clouded by low adhesion or the mechano-chemical fragile properties of the overall system. This project demonstrated the potential of HiPIMS technology for these aspects.
INDIVIDUAL CO2 BALANCE
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
The central purpose of the project was to develop a common understanding and a uniform approach for determining the product environmental footprint. In addition, a CO2 balance sheet was drawn up in practice using the example of the technical center at the Kunststoff-Institut, and recommendations for action were developed.
The project has shown that there are many individual ways to balance processes, which makes comparability difficult. In addition, benefits can be achieved through technical measures.
EMV SHIELDING THROUGH PLASTICS 2
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
Due to new design concepts and simultaneous technical function integration, cases of electronic components require innovative solutions with regard to the material. Electrically conductive plastics can contribute to the trouble-free operation of electronic systems, particularly with regard to shielding against electromagnetic radiation. Technology drivers are advancing digitalization, electrification and the increase in radio applications in the automotive, electronics, household or medical sectors. Devices must function or interact side by side without unintentionally influencing each other.
On the one hand, the project dealt with material technology issues. Conductive plastics for EMC applications, based on fillers such as carbon, steel or conductive carbon black, are nowadays well established. The use of the fillers increases the stiffness of the material, but at the same time reduces important housing properties such as impact strength and elongation at break. The toughness and elongation of conductive plastics can be optimized by using modifiers. Currently unresolved is the effect on conductivity and shielding effectiveness, which are being investigated in this project.
On the other hand, the connections of case components (e.g. by screws) require special consideration with regard to the joining situation. In contrast to metallic materials, plastics exhibit increased contact resistance in the joining area, which has a detrimental effect on the shielding behavior. By choosing more suitable geometry modifications, the penetration and leakage of electromagnetic waves can be prevented. The study of the influence of geometry variation was initially performed using 3D printing. This was followed by the injection molding of cases to evaluate the influence of different materials.
ANTIMICROBIAL SURFACES 2
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
The term “biocide” describes the property of a substance to prevent or reduce the emergence of bacteria, viruses or fungi. In the context of the collaborative study, the focus was on antibacterial efficacy. The growth of microbes and germs on surfaces is an undesirable effect in many respects, as it poses a hygiene risk, impairs the utility value of surfaces or leads to food spoilage.
The demand for biocide-treated surfaces has increased enormously in recent times, leading to a useful functional improvement in many products. Within the study, basic principles of antimicrobial action are shown and the possibilities of surface modification for plastics are presented. Different antimicrobial systems were researched, system suppliers were listed, the development status was scrutinizes and the application possibilities were differentiated.
FOAMING IN INJECTION MOLDING PROCESS
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
As part of the joint project “Foaming in injection molding”, the properties of components produced by thermoplastic foam molding (TSG) were scrutinized as a function of material, process and process parameters.
For example, the question of the achievable degrees of foaming and how these influence the mechanical properties was answered. There were also insights into which tests and measured values correlate best with the requirements of real components and how component stresses and environmental influences affect the properties.
OVERMOLDING ELECTRONICS 2
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
In the project “Overmolding of electronics”, the possibilities of encapsulating electronic components were to be further developed. Two focal points were set for this purpose. On the one hand, the aim was to validate the influence of the molding compounds and process parameters on the function of electrical components; on the other hand, the media tightness of different cable, molding compound combinations was investigated.
In the first project focus, a printed circuit board was designed which was equipped with different electronic components (electrolytic capacitors, ICs, Hall sensors, etc.). For this purpose, a measuring stand was developed with which it was possible to test the function of all components at component level. The printed circuit boards were encased in various thermoset molding compounds and molding parameters and subjected to a selection of component stresses. The function of the components was checked “fresh from the spray”, in the cooled state and after the component stresses. With many parameter settings, almost no influence on the function of the components could be determined.
For the second project focus, different cable materials were coated with the same molding compounds and process parameters. These test specimens also underwent component stressing. To determine the media tightness of the molded compound – cable combinations, the leakage rates were determined by means of pressure drop testing. Here, depending on the cable type, very high sealing densities could be determined.
HEAT-CONDUCTIVE PLASTICS 3
APPLICATION CENTER FOR SURFACE TECHNOLOGY (AOT)
Heat-conductive plastics are increasingly coming into focus within innovative development processes. There are many reasons for using thermally conductive plastics: economical production, lightweight construction, new assembly concepts, high design freedom, functional integration and the possibility of targeted plastic additives. However, a 1:1 substitution of existing materials within an assembly is not always effective. As a result of the high filler content and the associated loss of mechanical properties (elongation and toughness), the realization of e.g. snap-on hooks, fasteners, etc. on housings or other components is hardly feasible. The 2-component technology will be used to investigate the use of multi-materials with regard to the adhesion of the material systems, with the aim of being able to use thermally conductive plastics only in partial areas where heat dissipation is necessary.
In the course of increasing demands on materials, the topic of flame retardancy came to the fore in areas of E&E as well as in electromobility. Often, based on the requirements, a material classification UL94 V-0 is required by halogen-free flame retardants. Within the project, flame retardant systems available on the market were to be specifically investigated in the context of thermally conductive plastics based on material compounding with regard to thermal conductivity, mechanics, processability and flame retardancy.
Finally, the market for heat-conductive plastics is growing steadily, so a broader portfolio of materials is needed to give users more room for maneuver in the concept phase. In the previous projects, investigations were carried out exclusively with polyamide and polycarbonate materials. These results were then applied to other matrix systems.
