Plastics not subject to viscoelasticity (cold flow)

[QUOTE="Bcavender, post: 6006386, member: 641525"] I have been asked to find a machinable plastic (or dielectric) that will be subject to continuous loading (20 years) that will be subject to stress of appx 100 KPa at a max temp of 64C. While not a high speed or high energy situation, it is a rotating, close clearance application and the material cannot expand from its original dimensions without creating a potential frictional failure that could generate significant heat. I have read that 'cold flow' over a long time is primarily a problem with thermoplastic polymers 'only', but the information I have been able to pull up so far is very scarce and gives me little confidence about selecting a material. Not being in materials science, my ignorance is probably has me looking in all the wrong places. Can anyone shed some light about the cold flow being largely a thermoplastic problem and/or recommend a different source of viscoelastic data that I can use to find a plastic NOT subject to this long term phenomenon? All comments welcome! Bruce [/QUOTE]
