💡 How do you prevent fluoroelastomer seals from failing under extreme heat?
A properly selected compound stays flexible and blocks leaks across tough operating ranges.
* high fluorine content shrinks down molecular gaps to stop solvent swelling
* thick crosslinked matrix holds shape when thermal expansion hits peak levels
* handier alternative to silicone when oil resistance tops your priority list
