Clariant Masterbatches Continues Global Expansion of Engineering and High-Temp Resin Processing Units

On October 26, Clariant announced that its approximately CHF 10 million (US$10.13 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 for 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.
In order to work effectively in polymers that are processed at temperatures between 300°C and 450°C, masterbatches must be specially formulated using not only the same high-temperature base material, but also special pigments and additives that can stand up to extreme levels of heat and shear. All of this requires not only advanced extrusion equipment but also specialized auxiliaries, including pre- and post-drying equipment and multiple gravimetric side feeders.
“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. Around the world, our customers will soon have a local source of supply for these advanced materials, which means substantially reduced product-development and delivery times as well as back-up supplies that are critical to BCP (Business Continuity Planning).”
Besides masterbatches, the plants also can produce fully-compounded and pre-colored resins in small and medium quantities in collaboration with major resin producers. This is particularly important as these companies have begun to limit availability of certain colors and/or increase minimum order quantities, leaving many users in a difficult supply position.
