Gained importance of naphthenic tyre oils

The International Rubber Conference – IRC 2016 – brings together experts from all over the world with an interest in scientific and technical developments in the rubber and elastomer industry. Nynas is one of the participants in and Dr. Mika Lahtinen will be give a presentation under the title of “Getting the Best Out of Naphthenic Tyre Oils.

Nynas is one of the participants in Kitakyushu. On the morning of 27 October, Dr. Mika Lahtinen will be giving a presentation under the title of “Getting the Best Out of Naphthenic Tyre Oils: Utilisation of multiple variables analysis tools for optimisation of SSBR- and ESBR-based tyre rubber compounds”.

In his presentation, Mika Lahtinen confirms that Naphthenic tyre oils have gained importance and increased their market share as a result of the decline of aromatic extracts. In recent years the pursuit of sustainability has added one more dimension to tyre development: all tyre compounds must also be optimised to decrease rolling resistance.

“This means that development work is even more complex than before, and appropriate tools are needed to shorten time-to-market. Naphthenic oils are known for their tendency to improve fuel economy, so there is a strong interest in introducing them more quickly into tyre recipes,” confirms Mika Lahtinen.

In earlier studies, Nynas’ researchers investigated the performance of naphthenic oils compared with that of Group I-based counterparts, i.e. DAE, TDAE and RAE. They were able to show that the correct choice of low-PAH oils can significantly improve tyre performance and fuel economy in particular.

In the study, which will be presented at IRC 2016, they utilised a new approach, i.e. multivariate experimental design approach for an enhanced understanding of the effects of key components on the properties of cured rubber. 

“Compounds were prepared from both SSBR and ESBR, and it was observed that the multivariate analysis experimental design approach could be used to gain a greater understanding of final rubber properties. It may thus cut the development time and costs significantly,” summarises Mika Lahtinen.
The International Rubber Conference (IRC 2016) in Kitakyushu opens on 25 October. The venue is an ideal one, in view of the fact that Kitakyushu one of Japan’s most important industrial cities with significant manufacturing in fields including vehicles and tyres.

This is the fifth time that the IRC has been held in Japan since it began in 1966 in Paris and the event, including the large-scale exhibition, attracts thousands of visitors from all over the world. This year’s theme is “Innovation based on Basic Science”.
