Clariant Masterbatches Continues Global Expansion
Clariant International Ltd., Muttenz, Switzerland, is announcing its approximately CHF 10 million global initiative to expand its ability to produce color and additive masterbatches and compounds using engineering polymers and high-temperature plastics like PEEK (polyether ether ketone) is progressing on schedule.
Jeff Saeger, who heads the expansion program for Clariant, reports two extrusion lines at the Masterbatches plant in Ahrensburg, Germany, have been refurbished and can now run at temperatures up to 450°C. Another new line will be installed and running by the end of Q1 2017. In Shanghai, two new co-rotating extruders are now up and running and a smaller high-temperature unit has been started up in Singapore. Saeger says equipment for processing fluoropolymers has been installed in Lewiston, Maine, U.S.A, and new lines for specialty high-temperature compounds are now running in Holden, Massachusetts. A new black masterbatch line, for engineering polymers is schedule start-up in Holden in Q3 2017.
In addition, the Shanghai plant is being expanded to include not only additional compounding space, but also a new testing and quality-control laboratory. The Asian region already is served by a state-of-the-art lab in Singapore, but Clariant plans to add new physical, chemical and weathering test equipment there as well in the first half of 2017.
“Clariant is going all-out to meet increasing demand for high-temperature-compatible masterbatches and compounds around the world,” explains Jeff Saeger. “Processing knowledge and capabilities that were first developed in the U.S. and Singapore are now being replicated in Europe and China, and we are adding new personnel, including some with specialized expertise in key market sectors like electrical/electronics."
"Natural-Plus"Options for Global Manufacturers
Without high-temperature masterbatches, part producers have only a couple of choices. They can mold the parts in the resin’s natural color and then paint them, or they can use pre-colored compounds. However, Saeger explains, many companies need relatively small quantities of engineering and high temperature materials, making both these methods un-economical or even unavailable. “The major resin producers today are offering only a narrow range of standard colors and usually will not produce small quantities of special colors. Smaller custom compounders can produce smaller volumes but at higher costs,” he says. The solution, he continued, is “natural plus.” Processors buy readily available natural-color resin and then add a color concentrate (masterbatch) precisely formulated to achieve the exact finished color required. The advantages of this approach are many. The high cost of small quantities of custom-colored resin is avoided. Processors can buy larger quantities of natural resin and also have less capital tied up in an inventory of colored resin that may only be used occasionally. Storage space requirements are minimized. Production benefits accrue from centralized drying and handling of natural resin and faster color changes. Manufacturers are also much more flexible in responding to changing consumer color preferences.
The new investments are expected to be especially beneficial to manufacturers of electrical products and appliances, since many of these devices and the components in them contain engineering plastics that need to meet flammability-resistance standards promulgated by Underwriters Laboratories (UL). Clariant has obtained UL94 masterbatch listing for more than 200 commercial grades.
