SHOW PREVIEW | FAKUMA 2018


The Acrysmart masterbatch reacts to tempera-


ture to provide an automatically variable shading effect – it is clear at lower temperatures and turns a milky-white at higher temperatures. Intended for use in acrylic glazing sheet, the additive allows solar energy to be controlled without further energy input, the company says. � www.quarzwerke.com

product – REZYcom PP R15000FR V0 – that meets railway industry specifications. � www.polykemi.se


Polyplastics will exhibit the latest developments of its Duracon POM, Duranex PBT, Durafide PPS, Laperos LCP, and Topas COC resins. New Duracom POM grades include low-VOC emissions for the production of automotive interiors while the latest Durafide PPS grade is said to deliver improved heat shock resistance for a range of demanding applications. It will highlight an exam- ple part produced in Durafide PPS using “bump-off” moulding techniques, allowing undercuts to be created without the use of moving mould cores. The company will show its newly introduced


Duranex 457EV an unfilled high-impact PBT, which meets the UL2251 standard for electrical/electron- ics and automotive, and a range of laser welding resins. � www.polyplastics.com


Quarzwerke will present its Silatherm thermally conductive and Kaolin reinforcing fillers. It will also demonstrate its Acrysmart masterbatch for produc- tion of “intelligent” acrylic glazing. Five Silatherm grades are available, providing


improved thermal conductivity while maintaining mechanical properties. High filling levels can be employed due to the optimised particle size distributions, while customised surface treatments allow performance to be adapted to the polymer system. Kaolin TEC 110 is a phyllosilicate filler with an


extremely hexagonal plate-like quality that pro- vides good reinforcing performance. It is available with a number of silane coating options. In addition to its reinforcing effect, Quarzwerke says tests at its HPF Plastics Research Centre show that addition of Kaolin TEC 110 AST grade can significantly reduce the use of expensive flame retardants due to its release of crystal water.


54 COMPOUNDING WORLD | October 2018


Sikora will show its Purity Concept V pellet inspec- tion system configured for automatic offline inspection using an optical camera. It is the first time it has demonstrated an automatic system of this type at a show. The Purity Scanner is claimed to be more precise,


repeatable and reliable than human or conventional manual light table techniques. The Purity Concept V optical system uses a CMOS line scanning colour camera to identify and measure contamination and black specks in transparent materials and on the surface of non-transparent materials. It can work with pellets, sheets or moulded parts. The Purity Concept system is also available in an


X-ray based variant for detection of metallic contaminants in opaque pellets. � www.sikora.net


Teknor Apex will introduce a new series of high-heat glass-reinforced PA66 compounds that it says bridge the cost-performance gap between standard heat-resistant PA grades and costly specialty polymers. The Creamid 240 H7.5 Series compounds


provide the strength and stiffness of high glass filled engineering polymers while maintaining mechanical properties even after continuous service at temperatures of 240 °C. “These new materials exhibit lower melt and mould temperatures than competing PA66 com- pounds and high-performance products like PPA, providing economies in terms of energy consump- tion, cycle times, and tooling requirements,” says Dr Hartmut Elsässer, Global Director of Technology for Engineering Thermoplastics at the company. Currently available unfilled or with glass fibre contents of 35, 50 or 60%, the company says the compounds exhibit dramatically improved prop- erty retention when compared to similarly glass- filled standard PA 66 alternatives while costing around 30% less per kilo than high-performance polymers such as PPA or PA46. The new compounds process at around 280 to 300 °C; typical mould temperatures are in the range of 80 to 110 °C. Both are considerably less then PPA and PA46.
