[[Polytetrafluoroethylene|PTFE]], mentioned in the article, is the proper chemical name for Teflon. People who get here via a link or search might not realise that.

Hi I have a conflict of interest in that I work for Illinois Institute of Technology, but now that the ETFE-clad Kaplan Institute is built, it might be useful to make the Ed Kaplan Family Institute for Innovation and Tech Entrepreneurship, Illinois Institute of Technology, Chicago, Illinois a hyperlink: here's a possiblity: https://web.iit.edu/kaplan-institute [[User:Marydawsoniit|Marydawsoniit]] ([[User talk:Marydawsoniit|talk]]) 21:17, 14 May 2019 (UTC) |

How ETFE Compares to Chlorinated polyethylene
[edit]- Given Chlorine is easier to produce than Fluorine in a decentralized context (Ocean Water, vs Mineral Deposits), i was in truiged in alternatives to ETFE with similar properties
- Since Chlorine is still a halogen, i was interested if this could fill the roll, or if that little extra electronegativity is key
- Not too much information on the Chlorinated polyethylene page yet
- Also the Transmittance / Coefficient of Friction would be good to know, at least for Architectural + Agricultural Applications
- Here are some links i found in quick search, although they may need some double checking:
