Adhesives and Epoxies Q&A
-
We currently employ a solvent process using cyclohexanone to bond PVC tubing with an ABS molded hub. We are going to be switching from ABS to Pebax (thermoplastic elastomer). However, because we believe that there are issues with the cyclohexanone creating the bond with the Pebax that we desire, I’m looking for some information regarding our process. Is it appropriate to continue to solvent bond (maybe with a different solvent) or to switch to a new process (UV adhesive, for example)?Answered January 18th, 2012 by Expert:Solvent bonding typically works with amorphous thermoplastics such as PVC, ABS, PC, PMMA, and PS. Pebax belongs to the family of thermoplastic elastomers and generally offers good resistance to solvents. Depending on its grade and softness, it may swell in certain solvents but will not behave like amorphous thermoplastics do. If you replace the ABS with Pebax, you need to switch to a new bonding process. UV-light curable adhesives are a good option, and I would recommend that you try Dymax medical-grade adhesives 204-CTH-F and 209-CTH. They both adhere well to PVC, Pebax, and several other commonly used plastics.
