Right: New CamoTek concentrates from Teknor Apex have been intro- duced to produce mottled, swirled, streaked or camouflage colours
and Brilliant Gun Metal, but virtually any hue can be customised for specific applications. New CamoTek concentrates from Teknor Apex have been introduced to produce mottled, swirled, streaked or camouflage colours. The company says that the new concentrates for polyolefins enable injection and blow moulders to impart variegated colours that add shelf appeal to consumer goods or have practical functions for products used both indoors and outdoors. The variegated effects in products moulded on standard equipment require only an adjustment to process parameters. Any combination of colours is possible, depending on the desired effect. The concentrates can be used to impart intriguing patterns that enhance the shelf appeal of consumer goods like containers, lunch boxes or coolers, or can yield a camouflage look for products like kayaks or fishing tackle boxes. In the past, variegated effects were easy to

achieve, but this is no longer possible with modern processing equipment, according to John Wood, Technical Manager. “Improvements in screw design and mixing have defeated old methods of achiev- ing these effects,” he says. “CamoTek concentrates, combined with appropriate changes to process parameters, make such colours possible again.” Austria-based Gabriel-Chemie is constructing a new masterbatch facility to serve the Russian market and neighbouring countries including Belarus, Kazakhstan and Azerbaijan. The 27,500 m² site in the Vorsino industrial park is about 90 km south- west of Moscow. The industrial park attracts numerous Russian and international corporations due to its infrastructure and transport connections. During the first stage, around 400 million roubles will be invested in the new plant for a capacity of 2,000 tonnes per year. The maximum production capacity will increase gradually to reach 20,000 tonnes per year after completion of all the construc- tion phases.
Silvergate Plastics has engineered a new
generation of white masterbatch products to counter rising prices of titanium dioxide. The main ingredient used in the production of white master- batch is titanium dioxide but the company says that it has reduced the content by up to 25% without compromising on colour or opacity. They are also suitable for food contact applications and FDA compliant options are available. The company adds that the use of titanium dioxide is not restricted to whites and almost all solid colours contain it. The technology will be extended to high volume colours. Orion Engineered Carbons has introduced its
latest conductive speciality carbon black. XPB 633 BEADS has been specifically developed for thermo- plastics requiring conductivity and anti-static properties. The carbon black is claimed to exhibit excellent dispersion quality and improve compound melt flow rates and mechanical properties. Orion says that it continues to expand its portfolio of speciality carbon black grades and meet the requirements of a broad range of polymeric applica- tions and improve finished-product performance.
