    Thermal expansion of Alluminium

    It looks like my customer will now change the design of the part and glass filled PEEK of which we mould quite a bit already. Thanks to all who replied.

    Thermal expansion of Alluminium

    I am looking for a polymer that will have as near as possible the similar coeffiecient of thermal expansion rate as alluminium. Any suggestions ?

    Rexolite 1422

    Hi I too thought a cored out option would have been worth a try but they rejected this idea on the basis that they cant tolerate any voids. Thanks Steve

    Rexolite 1422

    Hi Pud This too is a stepped cone of varying sizes and customer also machines them at present. Some have quite thick sections and will be too big to mould as voids cannot be tolerated. I will give the LNP option a try as it sounds like both are similar applications. Regards Steve

    Rexolite 1422

    My understanding is that the dielectrice properties are the most important. The component is is part of an antenna for a satelite dish. Thanks

    Rexolite 1422

    Rexolite 1422 as I understand is a rigid and translucent thermoset. It has excellent dielectric, rigidty and dimensional properties, radiation resistance and is able to withstand high voltage. I1m looking for a injection mouldable thermoplastic grade as an equivalent, if it exists. Any suggestions ?
