All gone green
LANXESS has developed a new range of MDI polyether prepolymers
containing renewable, bio-based raw materials. Marketed under the
brand name Adiprene Green, the products are suitable as replacement
for existing fossil based polyether prepolymers to manufacture highly
durable polyurethane (PU) elastomers.
The overall objective to develop Adiprene Green was to create a
range of bio-based prepolymers which allow the PU processor to
produce components with a reduced CO2 footprint. Depending on the
system, a reduction of CO2 between 20 to 30 percent is possible
compared to fossil-based prepolymers due to the use of polyether
polyols based on starch. The share of bio-based raw materials varies
between 30 to 90 percent dependent on the targeted system
hardness. At the same time the existing PU processing capabilities
would remain applicable and the properties of the final polyurethane
elastomer would be similar to established elastomers based on fossil
based polyether or even better.
Big batches
The new metallic colour masterbatches from Tosaf Color Service put an
end to the previously typical and undesirable streaks and similar
surface defects on plastic parts. The key to this lies in the
manufacturer's compounding know-how acquired over the last few
decades in combination with the special effect pigments with a
rheologically optimized geometry that have only recently become
available. As a result, these masterbatches meet the requirements for
the cost-cutting, environmentally friendly use of components with
brilliant metallic finishes in visible areas. The new masterbatches are
available on different carrier systems and, at short notice, in customized
shades. They are suitable for all transparent thermoplastics, whereby
the brilliance increases with the degree of transparency. They can,
however, also be used in opaque plastics such as PC/ABS or PA/ABS
blends.
The further developed pigment technology makes a major
contribution to the considerable reduction in the separation effects that
are responsible for streak formation or color deviations, especially in
critical areas such as weld lines, cross-sectional transitions or with
distinctly three-dimensional, concave or convex contours.
Sample selection
Tektronix has announced the
new 8 Series sampling platform,
a disaggregated modular
instrument series boasting
parallel acquisition, with up to 4
channels per mainframe and the
highest measurement accuracy
for PAM4 optical signals on
multiple inputs simultaneously.
The 8 Series consists of the
TSO820 Sampling Oscilloscope
Mainframe, optical sampling
modules, and TSOVu, a new
software platform that runs
independent of the mainframe
on host PC for both live and
offline processing of acquired
data. Tektronix also introduces
the TCR801, an external optical
Down the tracks
A highly versatile and robust
epoxy coating system has now
been introduced by specialist
manufacturer, Indestructible Paint
with particular benefits for the
rail industry. The development –
centred on the introduction of
the company’s RWIP120 product
– signals the organisation’s
recent focus on the rail sector
and gains from some four
clock recovery module which
covers dual band ranges around
both 26GBd and 53GBd. These
instruments and software
provide a platform solution for
fast acquisition and analysis.
“Our customers are facing
new challenges with the
increased demand for
bandwidth and network
capacity,” says Matt Ochs,
general manager of the
performance portfolio at
Tektronix. “The 8 Series helps
solve critical problems by
delivering a scalable platform
that reduces test times, while
also providing fast, accurate and
repeatable test results.”

specification, offers a range of
performance benefits and,
significantly, is available as either
a one or two coat system.
