Materials | products in brief
❙ PolyOne has signed a cooperation agreement with Matériautech, the France- based plastics design and innovation specialist. Under the deal, PolyOne will supply a range of specialty engi- neering materials to Matériautech, which will produce a number of its GEM samples. These are used in all of the company’s design innovation centres, allowing designers to handle and evaluate materials during development of new prod- ucts. Matériautech has eight of these centres across France and Italy.

properties. The hybrid fillers have been
developed to offer easier processing and more consistent feeding compared to traditional boron nitride fillers. Momentive says that because they can
achieve high thermal conductivi- ties at lower loadings, its CoolFX additives can be more cost- effective solution for thermal management applications. Target applications for
Momentive’s CoolFX fillers
include: LED lighting; consumer electronic devices; aerospace and automotive cooling systems; motor and battery housings; temperature sensors; and heat exchangers. ❙

June 2013 | INJECTION WORLD 55 TPE Hexpol targets compression set
The Hexpol TPE group, which includes Elasto and Müller Kunststoffe, has announced a range of thermoplastic elastomer (TPE) compounds that have been engineered to deliver low compression set values. The new Dryflex CS grades
are based on SEBS and meet US and European food packaging regulations. The range extends from 40 to 90 shore A hardness with a service temperature range from -40 to 100°C. Compression set is the
STYRENICS Polyscope launches terpolymers
Polyscope has launched two new terpolymers consisting of styrene, maleic anhydride and N-phenylmaleimide. The two new grades, Xiran
IZ1018M and IZ0721M, are designed to create styrenic engineering plastics with high temperature resistance and low volatile residuals. The grades exhibit a glass transition temperature (Tg) of 175˚C or higher and can be exposed to higher processing temperatures with excellent
measure of permanent deformation remaining when an applied force is removed. It is an important performance indicator for applications such as seals, flexible connectors and gaskets. For a 40 shore A hardness
TPE, typical compression set values are 65 to 70%, according to Hexpol TPE. For the Dryflex CS range this is reduced to 40% (in tests carrried out for 22 hours at 100°C). The company says the
Dryflex CS TPE compounds are
also compliant with FDA and 10/2011 EC food contact regulations and provide improved organoleptic performance, making them suitable for a variety of food packaging applications. Dryflex CS compounds are
suitable for injection moulding and adhere to PP and PE for incorporation in two-compo- nent applications. The compounds are also easy to colour with transparent grades available. ❙
