is a D4 siloxane and it may be an impurity from the synthesis of the main siloxane surfactant.

Can you suggest someone we could discuss this with - someone in your organisation who is familiar with REACH and give us definitive guidance Best wishes

Fluorinated PA for Fluoropolymer Production Fluoropolymers are specialty performance materials that have a unique combination of performance properties.

[Conclusion] - Fluorinated grease is selected and used because of its advanced properties such as heat resistance, chemical resistance, and no effect on electrical contacts for which other lubricants' characteristics can't substitute. - Fluorinated grease is mainly used in the closed system of specific machines and parts for a long time. - Fluorinated grease is 10-1000 times more expensive than general-purpose grease.

Dear, This comment addresses 1,2,3,3,4,4,5,5-Octafluorocyclopentene (C5F8, CAS-No. 559-40-0).
