Friction, wear and lubrication of plastics

Right now polymer tribology is highly affected by the approaching banning of Teflon and other PFAS related materials. These are known for low friction and wear. This is why several of the talks at this ATV-SEMAPP seminar describe how PFAS could be substituted by more environmental friendly compounds.

Otherwise the basics of polymer tribology are worth remembering as they in fact define the success of your product outcome. A simple mistake, and you will be struggling with challenges that are irreversible.

Principal outcome
Industry and Academia will get updated in the advances within polymer wear and friction.

This seminar has been developed by Kristian Meldgaard (Senior Manager, LM Wind Power), Ion Marius Sivebæk (Associate Professor, DTU Construct & Tribologist, Novo Nordisk A/S) and Edwin Groothuis (Country Manager, Erteco Rubber & Plastics AB) from ATV-SEMAPP’s steering group for polymer technology.

Polymer tribology fundamentals

Ion Marius Sivebæk, Associate Professor, DTU Construct & Materials Specialist (Tribology), Novo Nordisk A/S

Tribology is the science and technology of two surfaces in contact and relative sliding. Polymers behave quite differently than metals when it comes to tribology. The coefficient of friction was established as a constant by Amontons in 1699 but this is mainly true for metals in dry sliding. Polymer sliding is dominated by adhesional interactions thereby rendering the coefficient of friction a non-constant. Several do’s and don’ts in polymer tribology will be revealed and a scientific/technological solution for very low polymer friction will be served. Without lubrication, of course.

Ion Marius Sivebaek works with tribology in both Industry and Academia. This ensures that the tribology is well looked after scientifically and at the same time that it is used in the real world, in a high volume production. Is there a better way to prove that you treat the topic in the right way?

Advances in wear and friction solutions

Erik Schwartz, Staff Scientist, SABIC

Sometimes neat resins may not provide the performance needed in term of strength, fatigue or wear. SABIC’s Specialties’ LNP™ compounds portfolio is based on a variety of reinforced and internally lubricated thermoplastic compounds to address such needs. In this contribution, we will present internally lubricated solutions with an emphasized on our fully compatibilized olefinic alloys which can serve as an alternative to PTFE based material and show that these can emulate the tribological performance and colorability of traditional lubricated materials while avoiding the use of PTFE.

Erik Schwartz is Staff Scientist of LNP & Copolymers product line for SABIC’s Specialties business. He obtained his PhD in Polymer Science from the University of Nijmegen in 2010. Before joining SABIC he spent two years at the Scripps Research Institute in California and two years at Eindhoven University of Technology as a postdoctoral fellow. He has co-authored >30 peer-reviewed research papers, > 20 patent applications and a book chapter. His current focus is on developing lubricated and structural solutions as well as sustainable thermoplastic products

Lubrication management in linear and rotary sealing systems and the implications of PFAS on Sealing Technology

René Vølcker, Account and Technical Manager, Trelleborg

Trelleborg’s Lubrication Management technology approaches hydraulic sealing and lubrication systems from a comprehensive perspective, in which each element is a complementary component of a unified whole. Lubrication Management technology uses adequate lubrication to reduce the load on each sealing element, thereby optimizing the performance of the hydraulic system in terms of friction, wear and lifetime.

Get in control of surface texture and protect functionality of your engineered products

Stefan Rosén, Surface Metrology expert, Toponova ab


Surface deviations are the small-scale geometrical deviations that always occur during manufacturing. Since surface deviations significantly impact the functionality, reliability, and performance of engineered products and systems, these deviations must be controlled. Surface texture is the term in ISO GPS (Geometrical Product Specifications) used to specify and verify allowed surface deviations on drawings, using parameters with tolerances and the correct measurement method. This presentation provides an introduction to ISO GPS and the toolbox for surface texture

Stefan Rosén is a surface metrology expert and a member of the Swedish Standardization Technical Committee 507, working group 06, focusing on ISO GPS: Metrology and Surface Texture. In 1995, he founded the knowledge-based company Toponova AB in Halmstad, Sweden. Since its inception, Toponova has been assisting leading manufacturing companies in the Nordic region by developing over 2,500 methods for managing and controlling surface quality in accordance with ISO standards

Influencees on Wear and Friction Systems

Holger Vandrich, Senior Business Development Manager, Lehmann&Voss&Co. KG

The presentation will provide a brief overview of the influence of fillers and their respective orientation on wear and friction testing. Processing methods of articles, or samples do have an influence that will be exposed. Last but not least, mating materials and their surface have an influence on wear and friction testing that should be observed.
The presenter will also show that there have been wear and friction compounds without PTFE around since long ago and explain why they are not widely known.

Measuring friction on plastic materials for toys

Martin Brorholt Sørensen, Senior Testing Manager, LEGO Group

From the first LEGO bricks were produced until this day, where millions and millions of bricks exist, only one thing has been holding them together. And that is friction. Because of the importance of friction the LEGO Group has studied this property of plastics for many years.
This presentation will focus on the current methods used for quantifying friction used by the LEGO Group and the background for why the methods are designed, as they are. Some of the challenges of measuring friction properties on plastics will be discussed and some applications of friction data will be introduced.

Martin Brorholt Sørensen has a MSc in Nano Materials Engineering from Aalborg University. Currently he works as Senior Testing Manager in the Materials Laboratory at LEGO System A/S.

A non-PFAS low friction coating

Ion Marius Sivebæk, Associate Professor, DTU Construct & Materials Specialist (Tribology), Novo Nordisk A/S

Many tribological coatings are made of PTFE (Teflon) due to the very low friction of this material. PTFE is a PFAS that are very soon to be banned due to their negative impact on the environment.
In this presentation, an example is given where polyethylene is used as a substitute for PTFE. It has the same friction properties as PTFE and can match the physical properties except in high temperature applications. It is shown how the polyethylene is applied to a steel surface and how the coating performs in a very harsh friction test.
