In passenger cars, “green” tyres have already proven to be effective in conserving resources. Evonik has now developed the silica Ultrasil 9100 GR that, according to the company's latest findings, is particularly suitable for use in truck and bus (TBR) tyres. In contrast to passenger car tyres, these use mainly natural rubber, which, in combination with the silane, places special requirements on the silica.

The Netherlands has prepared a proposal to support a possible restriction to address the risks from eight polycyclic aromatic hydrocarbons (PAHs) found in granules and mulches used in synthetic turf pitches, or in loose forms at playgrounds and other sports facilities. The proposal, prepared by the Dutch National Institute for Public Health and the Environment (RIVM) in cooperation with the European Chemicals Agency (ECHA), states that the general concentration limits set under REACH for eight carcinogenic PAHs in mixtures are insufficient for protecting those who come into contact with the granules and mulches while playing at sports facilities and playgrounds.

Nouryon (formerly AkzoNobel Specialty Chemicals) has introduced a new dibenzoyl peroxide (BPO) formulation, Perkadox GB-50, to customers in the composites market. GB-50 will replace Perkadox CH-50, a peroxide that is desensitized (or “phlegmatized”) with dicyclohexyl phthalate (DCHP), which the European Union recently reclassified as a category 1B Reproductive Toxin.

The need for life-time recycling loops for all kinds of products is steadily increasing. Tires and rubber products prove no exception. A recent paper from the University of Twente describes the devulcanization of rubber articles including tires of various sorts. It highlights what has been achieved for different major rubber types, but also what hurdles are to be overcome before rubber recycling is as obvious a technology as the manufacturing of first use rubber-articles.

Kistler, a specialist in dynamic pressure, force, torque and acceleration measurement technology, announced that it will share a stand with the Netzsch Group at JEC World 2019 (hall 6, stand R20) from 12 – 14 March 2019 in Paris, France. Visitors will be able to see how technologies from the two companies complement each other ideally in plastic composites processing. Both product portfolios will be showcased, and a simulation will show how the combination of information from mould filling and characteristic material values represents a major step towards intelligent part production, said Kistler.

Korean tire manufacturers are working on high-tech and innovative products in step with the fast-changing car market. For example, Kumho Tire is developing plastic tires for launching within this year. Tires to which special plastic materials are applied do not become flat and, as such, are regarded as futuristic tires. Kumho’s plastic tire can become the first one of its kind in South Korea if released as planned.
