– Degradation and Selection of Materials
4 June 2019
5230 Odense M
Time to market is becoming increasingly important for most companies that develop new products.
Over time, plastic parts can change properties due to external factors. This can result in the need for time-consuming tests in order to document and predict the lifespan. To limit the amount of testing, data available from suppliers can be applied in the design phase and make more relevant tests possible.
At this seminar, we will hear about known factors that influence the performance of plastic materials and how to design products using both traditional and additive/3D manufacturing.

Degradation of polymer materials during life cycle stages
Arnim Saalbrink, Lead Consultant, Danfoss A/S
Degradation of plastic and rubber parts does not only take place during service in application, but also in the earlier stages of the life cycle. This talk will give a short introduction to different degradation mechanisms along with examples of failure cases, where these different mechanisms play a role.Arnim Saalbrink is consulting specialist for plastic and rubber materials and processes at Technology Centre, Danfoss A/S. He has a chemical engineering background and has worked with polymer selection and analysis in various research and industry positions.

Behind the scenes at UL: material testing, recognition (yellow card) and selection
Wendy Stikvoort, Staff Engineer Chemicals, UL International
Knowing the material properties and requirements for a material in an electrical, electronic, and mechanical application can help you make more informed decisions on the choice of plastics, and lets you move from design phase to production faster. This presentation will discuss the following questions: What testing is done to establish the long term properties (RTI) of a plastic material? What testing is done in an outdoor investigation (f1)? It will also show where can you find the outcome of these investigations (in the database of recognized materials (Yellow Cards)). References will be made to general standards with requirements for plastic materials in E&E applications.Wendy Stikvoort has a background in chemical engineering and was previously employed by the Dutch Standardization Institute (NEN). Since 2006, Wendy Stikvoort has been with UL International (Netherlands) B.V. in Arnhem. Wendy handels projects for Plastics recognition, including properties as flammability, HWI, HAI, CTI, GW etc, as well as long term properties (aging of materials).

UV absorber strategies for polycarbonate product development and application
Rolf Wehrmann, Scientific Fellow, Covestro
Polycarbonate’s unique combination of properties – heat stability, transparency and toughness – enables a broad spectrum of applications. UV protected grades are of high importance in this context. Depending on the application, dedicated approaches are necessary to meet the demanded customer requirements. Typical examples are safety goggles, LED lenses for luminaires, automotive lighting and sheets for construction or sun glasses. Each of these applications require specially adapted and optimized formulations, so that the remaining key properties are affected as little as possible.After completing a thesis in organic chemistry from the Philipps University of Marburg, Germany, Rolf Wehrmann entered the main research department of Bayer AG in 1985. Rolf Wehrman has had several positions within research and development in the field of polycarbonates: production processes, QS, characterization and product development. His focus is on transparent qualities for optical, automotive, LED and medical applications.

Use of 3D printed materials in hearing aids: quality issues related to production and product lifetime
Jakob Lauritz Hansen, Director Product Quality Verification, Oticon A/S
The hearing aid industry has used 3D printed materials for production of custom made hearing aids for decades. This presentation will describe some of the developments of the process over the years, including materials used, the process improvements made, and how they each affect the quality. Special focus will be on the quality of the end product in test and in a lifetime perspective.Jakob Lauritz Hansen holds a MSc in chemical engineering and has 15 years' experience from the coating industry, mainly in product development. The last 8 years Jakob has been with Oticon in various quality positions.

Application design with additive manufacturing: material and process similarities, differences and what knobs to turn
Niklas Franke, Senior Engineer, Additive Manufacturing, Danfoss A/S
While additive manufacturing is considered a revolutionary technology by some, physics, chemistry and certainly the material science remain the same as for traditional manufacturing methods. However, the selective and layer based approach of additive manufacturing, which provides great geometric freedom, also allows for material modification on the voxel level and new hybrid materials, which enables new design possibilities. This presentation will give you an introduction to the unique design and material opportunities that additive manufacturing provides and also which knobs to turn to achieve it.Niklas Franke has been working at Danfoss as a Senior Engineer within additive manufacturing since 2017.
15:15 - 15:50
Characterization of surfaces and interfaces for prediction of product lifespan and performance of polymer materials
Torben Ruby, Material Specialist, Force Technology
Characterization services are in demand by a wide range of industries in connection with failure analysis, problem solving, quality assurance, product development, etc. But more precise methods of characterization down to micro and nano levels can contribute with new and valuable knowledge. They can contribute with a completely different basic understanding of the functional properties of materials, and the mechanisms that lead to degradation and failure or affect the durability and longevity of the materials. This talk will also present the OFGRIP project on surfaces and interfaces in industrial Products.Torben Ruby is Materials Specialist at Force Technology. He has a background in medico device development at Novo Nordisk A/S.
