"PPSU is often an excellent choice for components that are exposed to high temperatures and corrosive media because it has exceptional chemical resistance."
Those guys have a obvious type o . It would have been better than peek ifthose specs were true,it is probably Fahrenheit. It is 180 C .Check other sources. I doubt there is any plastic that can withstand that temp.
PPSU plastics offer: (best case)
- High operating temperature (180°C)
- Good chemical compatibility
- Excellent resistance to hydrolysis (suitable for repetitive steam sterilisation)
- High rigidity over a wide range of temperatures
- Very high impact strength
- High dimensional stability
- Very good resistance against high energy radiation (gamma and X-rays)
- Good electrical insulating properties
- Favourable dielectric characteristics
Polyphenylsulfone (PPSU) is a new material for the production of baby bottles. PPSU is a polyether plastic formally composed of bisphenol S (BPS) and 4,4'-dihydroxybiphenyl (DHBP), which both have slight endocrine activities in in vitro tests. So far, little is known about the presence and the...

""We found significant variations of PPSU materials from different producers with regard to polymer and oligomer chain end groups (methoxylation, chlorination), while total oligomer content below 1000 Da was similar (mean about 0.48%). BPS was not detected above 0.3 mg/kg polymer in any PPSU sample. Residual DHBP content ranged between 1.7 and 15.5 mg/kg polymer. The most common oligomer in all PPSU samples was the cyclic tetramer (about 1200 mg/kg polymer), which is the only cyclic compound below 1000 Da. Residual solvent, sulfolane, was determined to a maximum of 1300 mg/kg polymer.""

Bottom line is fuck plastics in vapes. Not only they contribute to environmental polution ,but there are very few that can withstand corrosive terpene vapors combined with high temps,also they have added coloring no one seems to take in account. This starts to smell of that Dotleaf hype trainwreck .
Cleaning just with hot water,is not something i consider cleaning.
I wonder if it will be more expensive in EU since it will have to offer minimum of two year warranty.
