Dear Yassine Adil,

I hope these informations can help you.

ABS plastic consists of three major components (Acrylonitrile Butadiene Styrene).  Solvents that have a similar organic structure can help break down, the components of the plastic.

This is solvated easily by Methyl Ethyl Ketone (MEK) Industrial Name

2-Butanone IUPAC Name

These chemical names are one and the same, but Industry and science have different naming conventions. It is just like the inches vs millimeters problem.  Regardless, 2-Butanone = MEK and is a cousin of the Butadiene linkage that holds the ABS polymer together. Acetone acts as a polar protic solvent that can generally solvate a wide variety of polymers. Both of these solvents can make a dilute ABS solution that can use the intermolecular forces to bond the plastic polymer to the glass. Intermolecular forces are what geckos use to run on glass, teflon, or any surface. Bonding with enough surface area on a molecular level allows the two objects to acts as one. This is how the solvated ABS prevents delamination without a hotbed, but by the same mechanism of intermolecular bonding.

Hi Dear Nodirali,

I forgot to tell you that I also tried the 2-butanone but also it doesn't dissolve well. I get a sort of two phases (such as a foam) I think that is solvated. Even with a small amount of ABS.

anyway thank you for this information.

Wish you a very nice day.

Dear Yassine,

Did you try dissolve it with pure acetonitrile or its water mixture? Also the sonification during dissolving process can be useful.

Give a try to pyridine if it is applicable. I understand that it is not a common solvent these days due to its toxicity. However, it is a powerful solvent. 

Thank you all for your answers. yes I will try Acetonitrile today but pyridine I don't think so.

Please check my answer to previous similar query: https://www.researchgate.net/post/What_is_the_best_solvent_of_Acrylonitrile_butadiene_styrene

The SAN (poly styrene-co-acrylonitrile) part of the ABS - about 80 weight-% -  is linear and soluble in many solvents like MEK, ethylenedichloride and many esters but a part of the polybutadiene part in not soluble for principle reasons. During preparation of the ABS the polybutadiene is partly crosslinked and the gelled part is only swellable in solvents but not soluble. For this reason you will never get an absolutely clear solution.

I personally tried THF and it was perfectly working in dissolving ABS. I have got a nice film of this polymer by using THF. Kind regards.

Acetone can be the answer for your question.

Best solvent for ABS:

1. Tetrahydrofuran (THF) at 40˚C.

2. Dimethylformamide (DMF) + 0.1% LiBr at 50˚C.
