New antimicrobial additive for flexible polymer applications
Sanitized, a leading producer of antimicrobial hygiene
functions and material protection for textiles
and plastics, has
developed a new
product for long-

lower molecular weight than Kraton G1652 polymer,
it still retains the high tensile strength and toughness
of Kraton G1652 while offering significantly lower melt
and solution viscosities. Kraton G1653 is suitable
for food contact and medical applications. Although
Kraton G1653 retains similar physical properties as
Kraton G1652, it has a much lower solution viscosity.
This low solution viscosity increases solid content
and decreases VOC of solvent based products,
yet maintains similar processability. For coating
applications, the increased solid level translates to
potentially reduced coating layers and lower labor
cost.
For sealant applications, the increased solid content
is expected to reduce shrinkage and costs associated
with solvent. Kraton G1653 also can be dissolved
in PCBTF at 20 percent solids, which may enable
formulators to replace organic solvents with PCBTF to
reduce VOCs associated with the final product.

flexible polymer applications. Besides thermal stability
and compatibility with most formulations, Sanitized
PL 14-32 is said to provide water resistance, as well as
It is designed to protect the material against unwanted
effects of microbes, like bacteria, mould, mildew, yeast
and algae – all of which can cause material destruction,
unsightly stains, cross contamination, odour development
and biofilm formation. Beside thermal and colour
stability, the antimicrobial efficiency was checked in
several formulations, the company reports. The product
is supported under the EU`s Biocidal Products Regulation
(BPR) and the active substances are approved under the
US EPA.
Celanese to announce five
polymer innovations
Celanese will introduce its five new polymer products,
as well as showcase three trends driving polymer
innovation and the advantages that come from
choosing an engineered material from Celanese at the
K 2016. These innovations are Celapex™ high flow PEEK
– high flow polymers that address injection molding
processing issues typically associated with PEEK.
The Celanese solution enables molding of thin wall,
intricate parts with high precision and tight tolerance
and facilitates ease of processing even at high filler
loading. Celstran® high flow LFT – Celanese offers one
of the most advanced lines of long fiber thermoplastics.
New high flow grades help molders and designers
to develop thinner (1.0-1.5mm thick walls), lighter,
and more efficient components and parts. Fortron®
flexible PPS – a highly durable, heat resistant polymer
is now available with the flexibility required for clips,
fasteners, tubes, and cable ties in today’s complex
automotive and industrial systems. Hostaform® M25IE
POM – to gain higher production throughput rates,
polymer sheet manufacturers are increasingly utilizing
the calendering process to produce polyoxymethylene
(POM) sheets in a wide range of thicknesses and sizes
that the market demands. MetaLX® appearance nylon
– by applying our experience in metal-effect and mold-
in-color polymers to nylon.
