Within the RX Crosshead Series –
available in sizes from RX2 to RX110 – the
latest product launch of RX5 made by
Rosendahl meets the very wide-ranged
demands in the field of cable applications
between 0.1 and 5mm conductor
diameter.
Perfectly balanced polymer distribution,
temperature- and pressure-profiles
guarantee a smooth and stable melt-flow
across the outlet zone. RX-Type crossheads
generally provide high-precision centricity,
therefore preventing over-sizing cable
wall-thickness and helping to save
material.
Enhanced flow-channel geometry
ensures short residence time of polymer
melt and enables a quick and easy change
of colour or material. Easy-handling is
guaranteed by a compact and modular
design, by high precision ball-centring
over an adjustable and self-sealing
tip-holder – or by the well-proven
fine-tuning-centring which is not only
requested especially in extrusion-lines for
fibre-optic cables.
Advanced RX5-Crosshead design keeps
away process-deviations and increases
quality and efficiency in extrusion-lines
for micro-coaxial-, LAN- and standard
power cables for automotive and
non-automotive applications as well.

S&E Specialty Polymers LLC, a producer of
speciality plastic compounds, has added
numerous concentrates to its product
portfolio.
While flame retardant (FR) concentrate
technology has been a speciality of S&E
since its founding in 2004, the company’s
research and development team has
been working on developing a variety of
other compounds and alloys to expand its
product line.
New offerings include:
• ultraviolet (UV) concentrates for poly
-olefin, PVC, TPR and other polymer
families
• FR concentrates targeting different UL
ratings
• combined FR and UV concentrates
• blowing agent concentrates
• custom designed concentrates for
specific customer needs
• percentage of active ingredients as high
as 75%
As part of the concentrate development
process, S&E invested in upgrading its
feeding system for its polyolefin line.
This helped the company to produce
consistent quality concentrates with
minimal waste.
