compound grades, which will be added during the year to its existing E-Tecrange. The new, permanent electrically conductive and ESD grades are all particulate based, with percolation characteristics claimed to be excellent. They will have surface resistance performance levels from 1 x 109 than 103
to less ohm-sq.
“The new grades will offer customers enhanced electrical performance for film, sheet and profile extrusion, injection moulding, vacuum forming and blow moulding, with less mechanical properties trade-off and the added benefit of enhanced process capability, excellent weldability and good aesthetics,” a company spokesperson says. Colloids is targeting medical devices, electrical and electronics, automotive, consumer and ESD packaging. It uses various forms of carbon in its E-Tec range and does not divulge which type is used in any one grade. Finnish speciality conductive compound maker
Premix recently extended its product slate with the introduction of an electrically conductive polyke- tone (PK), which it is targeting at fuel filler and system component applications. The Pre-Elec POK grade benefits from the very low gasoline permea- tion of PK and can be used as a replacement for PA and POM in multi-layer fuel system components. The company says the use of the new grade can

reduce weight and cut complexity by eliminating the need for barrier layers. Other recent introductions from Premix include a halogen-free and fire retardant electrically conductive PP – Pre-Elec FR-PP – which is aimed at production of anti-static ducting for industrial enviroments. The new material is said to offer a V-0 rating at 3.0mm. Also new is Pre-Elec TPU, a new line of carbon fibre filled TPUs that can be provid- ed in red, blue and a range of dark colours. The materials are said to be soft, abrasion resistant and non-marking and are pitched at applications such as rollers, handles and seating arm rests.
Dissipative acquisition Last November, speciality chemicals company Croda International acquired Finnish company IonPhasE, a supplier of static electricity protection products. At the time of the acquisition, Croda said IonPhasE has developed and supplies a unique range of anti-static additives that help to prevent damage to electrical components, increase the safety of chemical and food packaging and improve the long-term appearance of consumer appliances. It said IonPhasE’s inherently dissipative polymers (IDPs) release static electricity in a controlled way and are a natural extension to its own product portfolio.
