Good day, was wondering if Eng-Tips expert can lend their knowledge regarding this issue.
Our last rubber band batch has visible white particles showing on the rubber surface upon stretching. No changes in manufacturing process or formulation were made, which have been the same for some years now.
We suspect that it might be silica, but we're not sure. I'm hoping that anyone can offer their kind advise on how to proceed.
Thank you very much in advance, I greatly appreciate the help.
