Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.

Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions. Chemical effects of electric powertrain oils on rubber materials.

Background

New engine and transmission oils are regularly introduced at Scania and in the past, these introductions have mainly concerned new combustion engine platforms and new gearboxes. In recent years however, many of the introductions have been connected to electrification since the development of electrified vehicles and powertrains is in focus and progressing at high speed.

These new oils have more or less different compositions from the previous ones and therefore also the potential to have different impact on the various rubbers used in seals.

Generated test data could also form the basis for updating Scania’s material standards, both regarding used reference oils when testing and the requirements when evaluating. Updating the standards with relevant tests and requirements is critical to ensure lifetime performance of seals.

Objective

Assignment

You will study the impact different oils have on the properties of various rubber materials. The rubber tests will mainly be done according to established ISO-standards, the same standards that are also referred to in Scania’s own material standards.

The work consist of theoretical part where you will learn the basics about the properties of rubber materials. You will also familiarize yourself with the standards to be used when testing.

The practical part covers planning, preparing, conducting and evaluating of tests. You will investigate effects on the rubbers before and after exposure to oil by means of for example: tensile testing, volume change determination, hardness measurements and compression set determination.

In addition to the main work described above, your task might also include exploring the oils effect on a new rubber material never used at Scania before. This rubber, if the results turn out to be good, might then be added to list of future usable materials for Scania.

You will work in a dedicated and experienced team with a positive, creative and cheerful spirit.

The work will be performed at Scania Materials Technology in Södertälje.

Education

Master’s student in chemical or material engineering, chemistry or equivalent. Basic polymer knowledge is required.

You should have an interest in experimental work and enjoy team collaboration as well as independent work where you are allowed to design your own routines and workflow.
