Elastomer bonded with ABS, good solubility in Acetone 1

[polymer2006]

Hello,

I am looking for a type of soft rubbery material, which has a good adhesion with ABS and a good solubility in Acetone.

Definitely TPU is a very good candidate, but its solubility in Acetone is not good.

I tried SBS elastomer, but the adhesion with ABS was not good as TPU.

Thanks.

ABS is what I would call medium polarity, therefore you need a medium polarity elastomer to get adhesion (this is proven in books, not speculation). SBS is low polarity and I know from experience that it will not stick well to ABS.

One suggestion would be if you can use HIPS instead of ABS then the SBS will stick very well to it. Another would be to look for a more polar elastomer, perhaps something like nitrile rubber as that contains similar chemical groups compared to ABS (i.e. nitril groups). You could also try adding maleated polybutadiene (Fortirey
z or similar) to the SBS, it may act as an adhesion promoter. I am sure Pat can recommend something.

I would check what grade of ABS you are considering. All my books say ABS is not recommended for Acetone. I only deal with pipe grade from Samsung or GE.
