Silane-terminated polymer
Geniosil XM 20 and Geniosil XM 25 silane-terminated polymers can be used as binders in adhesives and sealants, where they can modify the mechanical properties, in particular impacting modulus. This is said to allow adhesives and sealants manufacturers to compound without the need for conventional plasticizers. In plasticizer-free adhesives, the two grades additionally enhance the bonding properties. In low-modulus sealants, they are said to ensure elastic recovery. As a result, Geniosil XM is said to open up applications in the adhesives and sealants sector that had previously been unaccessible to silane-crosslinking polymers. The two grades are said to complement the portfolio of silane-terminated polyethers that the company markets under its Geniosil brand. As with all silane-terminated polymers, Geniosil XM cures at room temperature under the influence of atmospheric humidity via silane crosslinking. In contrast to the other polymers, Geniosil XM 20 and Geniosil XM 25 only have one silane group at one of their chain ends, meaning they are crosslinkable only at that end.

Synthetic rubber solutions
Standard and advanced synthetic rubber solutions offered by the company include functionalized synthetic rubber and high-cis polybutadiene rubber. Rolling resistance, wet and dry grip, improved abrasion resistance and good handling are among the key properties consumers are looking for in a good tire, according to the company. The firm offers ongoing research and development efforts to continuously enhance its next generation synthetic rubber portfolio. Polymer solutions for energy efficient summer and winter tires are now available in experimental grades. Since high-performance functionalized S-SBR grades are said to typically be difficult to process, an alternative highly functionalized clear (oil-free) S-SBR grade was developed which indicates good extrusion characteristics and relatively low polymer-silica formulation viscosity. The experimental grade also indicates good wear characteristics.

Innovative applications for specialty carbon blacks
Innovative applications for specialty carbon blacks This brochure highlights the uses and benefits of specialty carbon black grades in applications beyond polymers, coatings and printing systems. These special applications include agricultural products, batteries, building materials, ceramics and carbides, graphite molded parts, latex and acrylic dispersions, non-woven materials, paper and refractory material. The 14-page color brochure describes the role of specialty carbon black grades in each special application. It details product recommendations based on the coloring, conductive, reactive and UV/IR protective effects benefiting each segment. The brochure also provides a comprehensive list of application-specific literature for more detailed information. The company produces high-performance as well as standard gas blacks, furnace blacks, lamp blacks, thermal blacks and other specialty carbon blacks that tint, colorize and enhance the performance of polymers, plastics, paints and coatings, inks and toners, adhesives and sealants, tires, and mechanical rubber goods such as automotive belts and hoses. Sable 7800 and Sable 3300 are clean mechanical rubber goods (MRG) carbon black grades with low NDM (non-dispersible matter) residue for extrusion and high-quality molding applications. The new ASTM D7724 NDM test is said to be a more reliable way than the classical sieve residue test to monitor and prevent the occurrence of surface defects in high quality MRG extrudates. The Sable products are said to be characterized by low NDM values to ensure exceptional performance, according to the company. They are said to enable customers to increase productivity, eliminate a step in the compounding process and reduce scrap rates.

Soy products for rubber
Soy products perform as process aids and reinforcing fillers in rubber compounds with a sustainability advantage. Vulcanized vegetable oil (including soy) as an extender and rubber substitute is said to result in improved ozone resistance and improved flow properties. Developments are underway that could help the environment and consumers alike by reducing the amount of petroleum-based oil used in tires, while simultaneously extending tread life. Tests are said to have shown that using soy oil in tires can potentially increase tread life by 10%, while reducing the use of petroleum-based oil. Improved mixing capabilities in the manufacturing process are said to have been demonstrated, and rubber compounds made with soy oil are said to blend more easily with the silica used in building tires. This can improve plant efficiency and reduce energy consumption and greenhouse gas emissions, according to the company. Bridgestone created an agricultural concept tire for large, four-wheel drive tractors with eight tires. Soy oil constitutes more than 10% of the 900-pound farm tire. At least two companies are said to be currently developing or testing tires made with soybean oil. Goodyear has a project which replaces petroleum-based oils in tire tread compounds and is testing tires for passenger cars. In Bridgestone's agricultural concept tire, soybean oil constitutes more than 10% of the 900-pound Firestone farm tire.

Cleaner carbon blacks
Carbon black, one of the world's most widely used industrial chemicals, is produced by this company with 90% fewer emissions, while simultaneously creating an alternative energy source. Conventional carbon black production uses crude oil or coal tar in its process. Alternatively, this company has invented, developed and perfected process technology that converts pipeline-grade natural gas into carbon black and clean burning hydrogen. The result is said to be high-grade carbon black that is manufactured and produced in the United States. The only co-product of the process is said to be hydrogen gas that can be used in a number of processes, including generating clean power.

Carbon blacks improve tires
Three rubber carbon black products for creating more fuel efficient tires have been introduced in response to consumer demand and federal standards for vehicle fuel economy. These grades are said to offer reduction in rolling resistance via narrow particle size distributions and lower sidewall hysteresis, and lower air permeation through the inner liner for better tire inflation consistency. For sidewall applications, blending Ecorax S 204 combined with N300 series grades is said to reduce sidewall hysteresis significantly, and thus lower rolling resistance and improve fuel efficiency, while maintaining other key tire properties. Ecorax S 204 is said to achieve the lowest hysteresis of any furnace carbon black. Ecorax S 206 reduces air permeation through the inner liner by up to 25%, maintaining tire air pressure critical to vehicle safety and tire life in addition to fuel efficiency.
