Master’s Thesis Worker, R&D (silica-filled rubber compounds)

Master's Thesis Worker, R&D

We are looking for a Master’s Thesis Worker to join our R&D team at Nokian Tyres.

Thesis Topic

Validation of a new method for crosslink density determination in silica-filled rubber compounds

At Nokian Tyres’ R&D, laboratory testing plays an important role in developing and evaluating advanced rubber compounds for high-performance, safe and more sustainable tire technologies. Crosslink density is one of the key parameters for understanding rubber network structure and material performance, creating a need for a fast and reliable laboratory test method. Although several methods are already available, further research is needed to evaluate emerging techniques and identify the most suitable approach for tire rubber formulations.

Nokian Tyres’ R&D is looking for a MSc thesis worker to validate the new method for crosslink density determination in silica-filled rubber compounds. The objective of the thesis is to assess whether the new method could serve as a reliable tool for measuring crosslink density in silica-filled compounds.  The practical work will include Rubber Process Analyzer (RPA) measurements, mechanical tests, and comparison with reference methods, such as swelling-based crosslink density determination using the Flory-Rehner equation and bound rubber determination. In addition to physical testing, the work includes data analysis, and evaluation of suitable filler correction approaches. An interest in polymer physics and data analysis is highly beneficial.

The thesis will be completed under a scholarship/grant arrangement. The intended start date is November–December 2026, but the exact schedule is negotiable.
