industry, for use in rubber, plastics and pigment applications, comments Bill Cole, director of product management at tyre-recycling firm Delta-Energy Group and an ASTM International member. At this early stage in its existence, the rCB industry needs ‘a set of common terminology’ in order to communicate effectively to product users and to each other, Cole explains. ‘Unique industry terms’ are defined in the new terminology standard, which will be added to as new standards for rCB are developed, he reports. The rCB products recently developed by several manufacturers are distinct from ‘char’ products, according to Cole. Despite both product types being derived from the thermal degradation of rubber compounds, typically sourced from tyres, there are significant differences in the way they perform in rubber applications, he reveals. ‘Having common terms provides a strong basis from which to clearly distinguish the value of rCB from char products. It also allows us to discuss performance within proposed applications’, Cole observes. Manufacturers of rCB products will find the standardized nomenclature and new methods useful when communicating product performance, he says. In addition to defining terms, ASTM D8178 includes an appendix of ASTM International standards developed by other committees that are currently recognized as available for use in the rCB industry. This includes those norms formulated by the carbon black committee, which was established in 1956. More information: www.astm.org
MARKETS Ceresana analyses the market for polymer stabilizers

cast to see steady growth over the next six years, attaining a predicted value of US$5.5 billion by 2025. The study examines the prospects for tin-based, leadbased and calcium-based stabilizers, as well as for liquid mixed metal stabilizers and other products. These indispensable additives protect polymeric materials from the effects of heat, UV light or oxygen, ensuring safe production, processing and use. Ceresana expects global consumption of calcium-based stabilizers to increase by 3.9% per year during the forecast period to 2025, while global demand for tin-based stabilizers is predicted to increase to about 231 000 tonnes/year by the same end date. Lead-based stabilizers have completely disappeared from the market in the European Union and are being increasingly replaced by calcium- or tin-based products in other regions too as demand for more environmentally friendly alternatives grows. In Europe, calcium-based stabilizers are by far the most popular type but North America utilizes tin stabilizers most frequently, Ceresana finds. By geographical region, Asia Pacific is the largest market for stabilizers, currently accounting for a share of 57%, followed by Western and Eastern Europe. The production and processing of polyvinyl chloride is one of the most important application areas for stabilizers worldwide. Currently, the largest application area by volume is the production of plastic pipes, which consumed about 375 000 tonnes in 2017. Production of profiles ranked second, followed by cables, films and flooring, all highly dependent on the construction sector. In Western and Eastern Europe, the application of stabilizers in profiles tops the regional market, while in Asia Pacific the plastic pipe sector dominates. In addition to analysing the stabilizers market according to stabilizer type, application area and region, Ceresana’s study also examines 16 countries in more depth and profiles 63 of the most important manufacturers of these additives worldwide. The 310-page report contains 58 graphs and 110 tables; prices range from E3500 for a single-use pdf up to E7900 for a corporate licence. More information: www.ceresana.com/en
