W. Conshohocken, PA – ASTM International’s recovered carbon black (rCB) committee (D36) is developing a proposed standard that will be used to differentiate between different rCB products and provide quality control tool for producers and users.
Read MoreOne-component liquid silicone rubber cures at room temperature by reacting to the atmospheric humidity. After curing, because it has superior combined characteristics, including heat resistance, cold resistance, weather resistance and outstanding electrical properties, it is used as adhesive/sealing materials and coating materials in such products as component parts for electric vehicles (EV), semiconductors, and electric/electronics. Furthermore, because it cures at room temperature, it is not necessary to have a heating furnace and ultraviolet (UV) irradiation equipment. Accordingly, these new products will contribute to reducing environmental impact
Read MoreThe March issue is now available online. Issue emphasis is on Custom Mixing & Compounding. Includes Suppliers directory for 2022.
Read MoreDue to the long service life of the washing machine, all polymer parts, especially rubber parts, need to have a service life of at least 10 years, which means excellent resistance to aging.
Read MoreThe following directory lists custom services suppliers. The first part lists custom rubber mixers along with plant locations, equipment, mixing capabilities and whether technical service and/or recipe development are offered. A directory of companies that offer various custom services to the rubber industry follows.

Read MoreAustin Black 325 is a finely divided (below 325 mesh) powder produced from high carbon content, low volatility, sustainable bituminous coal. It has different properties compared to carbon black, including a lower specific gravity of 1.30 versus 1.80, a platy ground structure versus the reinforcing morphology of carbon black (figures 1 and 2), and a lower surface area in comparison to carbon black. Beyond its carbon composition, it is more similar in structure to platy fillers like clay and talc. The specific gravity comparison to other platy minerals (1.30 versus 2.50) provides economical and efficiency gains.
Read MoreNR is usually masticated for viscosity reduction through breakdown of the long molecular chains to facilitate subsequent processing steps (e.g., extrusion and calendering) and improve rheological properties, such as die swell, shrinkage and building tack.
Read MoreThe new 25-kiloton line at the facility in the northern city of Ravenna produces both specialty and technical rubber carbon blacks, primarily for the European market.
Read MoreThe most recent Ceresana report concerning the world market for carbon black shows that this important industrial base material is still mainly produced by incomplete combustion of fossil raw materials, most often from heavy petroleum fractions. The current market report predicts that the demand for carbon black will rise to 17 million tons per year by 2030
