Any cruising vehicle will come to a halt after some time, however a train on steel wheels running on a steel track will roll much further than a bus of the same weight on a tarmac road, since the deformation of the rubber when it rolls on tarmac is much more than the deformation of steel wheels on a steel track.

Reduction of rolling resistance has been at the top of every tyre manufacturer’s priority list and this has to be done without compromising on factors like life of the tyre, safety, comfort.

The tyre manufacturer has to work with high quality materials to get to the desired result of reduction of rolling resistance and one solution provider Nynas AB has a product which could be of help in this endeavor.

Nynas is a different kind of Oil Company –their credo is” We want to use oil, not burn it”. With around 1,000 employees, production facilities in Europe and South America as well as offices in over 30 countries, Nynas is dedicated to researching, producing and supplying specialty naphthenic oils and bitumen for a growing global market. Their aim is that together with their customers, and the knowledge base and technology available with Nynas they will  find new applications and meet new challenges that can help shape society.

Nynas AB launched a new process oil for the rubber and tyre industry Designed to meet just about any demand, tyre oils from specialty oil producer Nynas AB helps customers tackle challenges such as rolling resistance, fuel economy and reliable supply. A new high performance grade has now been added to the product slate. The all-new rubber process oil Nytex 842 provides all of the advantages of pure naphthenic oils, such as high compatibility with polar and non-polar rubber, good process ability and excellent low-temperature properties.

Furthermore, its low color allows for the formulation of innovative colored products. Dr. Herbert Fruhmann, Global Marketing Manager for Tyre Oils, explains: “Nytex 842 has been developed to support the challenge facing the tyre industry to meet the ever-growing demand to improve fuel economy whilst not compromising on road safety or wear.” Nytex 842 is produced using future-proof, state-of-the-art hydro treating technology, and the polarity was defined to ensure that the product is compatible with a wide range of polymers, including natural rubber, (functionalized, solution- and emulsion-) SBR, polybutadiene rubber and halobutyl rubber, as well as EPDM.

The new product comes with a high viscosity in the Bright stock range, a low glass transition temperature and a high flashpoint for safe process operation, which makes it very attractive for high-temperature curing operations in EPDM applications. “The product’s glass transition temperature (Tg) is -55°C. We believe that Nytex 842 can significantly reduce the rolling resistance of tyres and also improve traction at low temperatures,” notes Dr. Markus Hoffmann, Global Technical Manager for Tyre and Rubber Applications. Nytex 842 is designed to meet all present and foreseeable health, safety and environmental demands on polycyclic aromatic hydrocarbons (PAHs) as set by legislative bodies around the globe for tyre and for general rubber goods, making it a sustainable and safe choice for the tyre and rubber industry. Nytex 842 will be available from Nynas global depot network, serving the needs of a globally active industry.
