Frequently Asked Questions
What is the difference between FKM and FFKM?
While FKM offers good resistance, FFKM contains higher fluorine content and no C-H bonds, providing near-universal chemical resistance and much higher temperature limits.
Can FFKM O-rings be used in semiconductor plasma?
Yes, our specialized semiconductor grades are designed to resist erosion in aggressive plasma environments while maintaining high purity and low outgassing.
