As I said, I do not believe the problem to be with the ABS component. In our experience with this resin, we never had this kind of problems. We only had this problem when processing PC/ABS, which is why I think the problem is in the conjugation of polycarbonate with metallic stearate.
The fact...
The problem, I suspect, shouldn't be with the ABS component, as we have processed ABS with no problem in the past, only a decrease in the lubricant perfomance.
But now, the end product shows some strech marks that dissapeared with the substitution of the stearate (metallic for an amide). I see...
Hi! A small question about lubricants:
Is there any incompatibility between metalic stearates (zing e.g.) and PC/ABS? If so, which would be the correct lubricant?
