In flexible PVC, unwanted color development is a frequent problem. Colors can show up unexpectedly: it can happen immediately after high temperature processing of flexible PVC or weeks or months after a plastic part is produced. It leads to scrapped production and product failures in the field, which can both be very expensive. But how to solve the issue when you are not sure about the cause?


Watch this tutorial and learn the 8 main causes behind all the cases of color development. Our specialist Paul Daniels will also uncover what you should do to avoid each of these pitfalls. You are just one step away from saying definitive good bye to color issues!
