Lithaum compounds for ptfe etching
Wetting the surface of PTFE with commercially available solvents and liquid adhesives is virtually impossible. The exception to this is with special halogenated solvents that have a surface energy lower than PTFE, such as 3M's FC series solvents. These 3M solvents are, however, toxic and expensive. Additionally, even if wettability is acceptable, the PTFE will not form hydrogen bonds which are the primary source of adhesion strength. The PTFE surface therefore must be chemic… WebOther Standards From NEC, UL, SEMI, and CSA. Standard Number. Title/Description. UL1581. 200 °C (392 °F) fixture wire, Teflon™ FEP.
