Since people want to switch to resins vs. glass

Migrated topic.

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 Chemical Compatibility Chart - LDPE, HDPE, PP, Teflon Resistance

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

i second that! wonderful, useful info and all of us doing any sort of extracting are greatly helped by this.

much love for sharing this !!

...and GRATITUDE!!
 
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
 
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.
 
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.
