Any adhesive needed for PVC and PC natural bond?

hi all,

in our operation, we insert the vial stopper and rivetted injection port both with polycarbonate surface into PVC tubings without applying any adhesive. it should form a natural intact bondage between PC and PVC even without adhesive application, right?

what if the vial stopper and injection port was inserted into tubings when the tubings are wet with solution after filling, will this affect or degrade the bondage formed between the PC and PVC? do you guys have any literature to support this?

many thanks for help.

I doubt it to be honest.

At the PVC/polycarb interface you will indeed get some reaction but in the longer term this is likely to result in the degradation of the pvc. In the short term you may get some sort of bond but I doubt it would be repeatable in terms of the strength of the bond formed or reliable.

Anyway that is just speculation based on what I remember from university lectures. You want to be doing some experiments to determine what your needs are. Figure out what your requirements are, create experiments using both this "natural bond" you are talking about and using adhesive, perform the experiments and analyse your results. At the end of this you will be able to make conclusions, as long as you design your experiments correctly.
