I need to design a small, lightly loaded part (essentially a bumper to prevent two other metal parts from making contact) for use in a hot water valve. May see glycol/water and some salts (corrosion inhibitors). Normally, I'd design this part as a teflon piece and attach it with fasteners, but the boss doesn't want a fastener in this location. This leaves me with a heat-staked or ultrasonically-staked version being the design, which has lead me to look at either polysulfone or PPO. Any experience with either of these in hot water with light grazing/contact/abrasion?
Thanks,
