material for dual wiper secondary seal

[HubertChen]

Hello everybody, I work in oil & petroleum company in east Asia. My boss ask me if I can find the laminated PTFE(PTFE sheets laminated to both side of dipped glass fiber) to be the material of dual wiper secondary seal. After searching on the internet, I found some of the oil tank manufacturers that can meet our requirement, however, what I think is if I can find the supplier of this kind of PTFE, I think we don't have to find the oil tank manufacturer. After all, if someone knows the supplier of this kind of PTFE, please make some recommendation to me. Thanks in advance.

PTFE does not make a good wiper because it has poor mechanical and wear strength. You can get laminated PTFE in whatever thickness you want, in multiples of 2 and 3 mil thicknesses, in whatever width and length you want. Is this for an internal or external floating roof?
