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
ment of its flame retardant portfolio. Its POLYfill PP HC has been extended to include flame retarded glass fibre reinforced grades with up to 25% filler content while a new glass reinforced UL94 V-0 PBT for thin wall moulding is under development. It will also show examples from its POLYfill PP
HC line. These high performance reinforced PP compounds can be used as an alternative to PA6, PA66 and PBT in some applications – it says several customers have replaced PA6 GF 30% with POLYfill PP GF5030HC. Polykemi says it is now developing a 35% glass reinforced PP HC to substitute 30% glass reinforced PA66. Benefits are said to include reduced weight, easier processing and low moisture absorption. The display will be completed with a full range
of recycled compounds, including examples from its REZYcom line which combine selected recycled and virgin material. It will show a REZYcom PC/ABS grade formulated to meet automotive finish and colour requirements and a new fire retarded product – REZYcom PP R15000FR V0 – that meets railway industry specifications. �

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 example part produced in Durafide PPS using “bump-off” moulding techniques, allowing under- cuts to be created without the use of moving mould cores. The company will show its newly introduced

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 compounds and high-performance products like PPA, providing economies in terms of energy consumption, cycle times, and tooling require- ments,” 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 kg than high-performance polymers such as PPA or PA 46. 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. Teknor Apex sees applications for the Creamid 240 H7.5 compounds in automotive under-hood components such as charge air cooler end caps, air intake manifolds, quick-fit connectors and radiator end tanks, as well as electronic connectors and lamp sockets. �

Victrex will introduce its FG food-grade range at Fakuma. New to the company’s portfolio, the move is intended to meet the specific regulatory and quality requirements of OEMs in the food equip- ment sector. Offering significant benefits in terms of cost and performance compared to metals, the new grades are aimed at applications in cookware and beverage dispensers for commercial and domestic use through to industrial applications in conveyor systems, aseptic processing, sensors, gears, and nozzles. �
