Carbon nanotubes for new thermoplastics Long term cooperation is the goal for Bayer MaterialScience as it cooperates with Clariant Masterbatches on carbon nanotubes for new thermoplastics.
The excellent electrical conductivity and mechanical strength of Baytubes* carbon nanotubes were the decisive factors leading to a cooperation agreement on thermoplastics between Bayer MaterialScience AG and Clariant Masterbatches (Deutschland) GmbH. Bayer MaterialScience will supply Clariant with industrial quantities of high-quality Baytubes for the manufacture of development and sales products for compounds and master batches. The carbon nanotubes, CNT for short, will initially be used in the new CESA® conductive CNT product range. Potential applications for the resultant compounds include electrically conductive machine components and packaging for delicate electronic components such as computer chips. "Clariant is one of the world’s leading suppliers of thermoplastic
compounds and master batches and is the ideal partner for us to promote
greater use of Baytubes on an
industrial scale thanks to its wealth of experience in compounding technology
and application development," explains Martin Schmid, head of global
Baytubes operations. Compounds are formed by combining one or more plastics
with fillers or aggregates. Master batches are additives such as dyes
that are incorporated in high concentrations into polymeric carriers and
mixed into plastics to give them specific properties such as a particular
color. Clariant also sees great growth potential in cooperating to develop
innovative materials. According to Christian Funder, Product Manager at
Clariant Masterbatches (Deutschland), "The CESA conductive CNT product
range represents a valuable addition to our portfolio that has a particular
advantage over semi-conductive products based on carbon black in terms
of its mechanical and melt flow properties." The cooperation between Bayer MaterialScience and Clariant on Baytubes is a long-term arrangement that is intended to extend to other product areas in future. According to Schmid, "The objective is to enjoy joint growth on the expanding market for compounds and open up new markets. Clariant’s wide-ranging product portfolio - including everything from commodity plastics such as polyethylene to engineering thermoplastics such as highly heat-resistant polycarbonates - represents a major advantage for us in this respect." Clariant Masterbatches (Deutschland) GmbH has branches in Lahnstein,
Ahrensburg and Döbeln and is part of Clariant’s Masterbatches Division,
a world-leading Swiss company for specialty chemicals headquartered in
Muttenz, near Basel. The Clariant Group includes over 100 companies and
is represented on five continents with a workforce of around 21,000. In
2007, Clariant generated sales amounting to 8.5 billion Swiss francs.
It is split into four divisions - Textiles, Leather & Paper Chemicals,
Pigments & Additives, Masterbatches, and Functional Chemicals. If you're an employer looking to fill a job opening, click here to find out about posting your job listing through Jobwerx.com. See all the Press Releases from Bayer sites. Read a recent article about -
