I see an increasing trend in people utilizing resins/plastics for use in thier extractions verses using glass. The upsides to this can be seen immediately, they are lighter, stronger, more resiliant to damage than glass, but they also have their downsides. Certain plastics are susceptable to damage using hydrocarbon solvents, so I did some searching and found this nice little cheat-sheet as to which plastics are safe for use with your solvent. Green: 30 Days of constant exposure causes no damage. Plastic may tolerate for years. Blue: Little or no damage after 30 days of constant exposure to the reagent. Yellow: Some effect after 7 days of constant exposure to the reagent. The effect may be crazing, cracking, loss of strength or discoloration. Red: Not recommended for continuous use. Immediate damage may occur. Depending on the plastic, the effect may be severe crazing, cracking, loss of strength, discoloration, deformation, dissolution or permeation loss. For reference, I sourced this chart and the color codes from http://www.calpaclab.com/pages/chart.htmlDarkerweb attached the following image(s):  Chemical_Reference_Summary.jpg (175kb) downloaded 279 time(s).

This is very helpful for a number of applications. Thanks! intechgration is a fictitious persona. anything he says, writes, suggests, or does are simply the products of someone's imagination and have no place in reality.

Right On Darkerweb!!! Thanks for posting this up! I'm sure a lot of people will benefit from having this info in an easily understandable & comparable chart! I'm going to copy this thread over to the "A/B" & "STB" pages of the "Extraction" section so it can be more readily accessed. Thanks again, great find! Cheers WS All posts are fictional short stories depicting the adventures of WSaged!! None of these events have actually happened and any resemblance to any real persons or incidents is totally coincidence!!!!!!!!!!!!

that's awesome! If for no other reason, the Nexus is amazing simply because it's comprehensiveness makes for an incredible single reference point. This is another outstanding tool and reference to add to the collection. Thank You Wiki • Attitude • FAQThe Nexian • Nexus Research • The OHTIn New York, we wrote the legal number on our arms in marker...To call a lawyer if we were arrested. In Istanbul, People wrote their blood types on their arms. I hear in Egypt, They just write Their names. גם זה יעבור

Seems to say that PVC is all right for butane honey oil extractions, but it may be advisable to only use a tube once?

Does this mean you can't use Xylene with HDPE?
Or am I confused with the definition of aromatic hydrocarbons?

Are there any other names for FEP, TFE, PFA and FLPE? I have no clue what these are or how to find containers made of these. ––––––
DMTripper is a fictional character therefore everything he says here must be fiction.
I mean, who really believes there is such a place as Hyperspace!!

Normaly these containers should have the type of material they are made from on them, take a look at you milk container, the plastic one if you use those, underneath it it should say HDPE. Not sure about the rest of them though.
