the new product stands out with its high thermal stability, wide process window, and its outstanding flow. It can withstand temperatures of up to 280°C.


being used as the key base ingredient in a highly temperature resistant and light stable compound for high-performance LED applications. It is also used in a compound for production of the moveable lens module units found in smartphones. In existing lens modules based on LCP, the presence of weld lines can lead to breakage of the movable frame, Evonik says. Simon Ting, global business director for high-tem- perature polymers at Evonik Resource Efficiency, says


Advanced modelling At Fakuma, DuPont was showing how its anisotropic CAE modelling capability has been used to predict the performance of a series of structural automotive engine brackets made in a glass reinforced version of its Zytel polyamide 66. DuPont says it uses advanced micro- mechanical material modelling with Digimat to optimise FEA modelling of glass reinforced materials, to accurately analyse local changes in material properties, and to identify any structural weaknesses in the design. The brackets, which stabilise and align the engine,


were developed in close collaboration with Elring- Klinger and Daimler on a shorter development cycle time and at lower cost compared to standard die-cast aluminium. In addition to its ability to absorb noise, vibration and harshness (NVH), this optimised Zytel grade provides the required blend of strength, stiffness and resistance to creep, deformation and fatigue to stand up to the loading and stress.
