Product Q&A
What is Xiechang’s high-temperature Viton (FKM) diaphragm made of?
A fluororubber diaphragm built on aramid fabric: a meta-aramid reinforcement layer coated with FKM (Viton). Aramid keeps its strength at flue-gas temperatures where ordinary nylon fabric would soften, and FKM keeps sealing where nitrile hardens. The service temperature range is in the parameters table on this page.
