STOCKHOLM—Nynas A.B. has introduced a new process oil grade for rubber processors seeking to reduce rolling resistance and increase fuel economy.

The product, labeled Nytex 846, is claimed to provide all the advantages of pure naphthenic oils, such as high compatibility with polar and non-polar rubber, ease of processing and excellent low temperature properties. The product also is designed to meet health, safety and environmental demands of legislative bodies around the globe, including all requirements on polycyclic aromatic hydrocarbons (PAHs), Nynas said.

The introduction supports "the continuing challenge the tire industry faces to meet an ever-growing demand to improve fuel economy without compromising on wet grip or wear," said Herbert Fruhmann, global marketing manager for tire and rubber oils.

The process oil is produced using state-of-the-art hydrotreating technology, and its polarity is designed to ensure it performs well in conjunction with a wide range of polymers, the company stated. These include natural rubber, SBR, polybutadiene rubber, halobutyl rubber and EPDM.

The product has a glass transition temperature of -46°C, according to Mika Lahtinen, global technical manager for tire and rubber applications at Nynas.
