Discoloration of PVC Products: How to Minimize or Avoid It

This is a Past Course

Recorded on May 29, 2019

Are you faced with discoloration issues like photo bluing, photo pinking, photo greying, yellowing and chalking in your colored PVC products (pipes, cables, membranes…)?

In this new course, expert Michael Schiller will explain reasons and mechanisms of discoloration. He will explain which raw material can cause the problem and eventually how to change product composition to minimize the issue at the formulation stage itself with the help of practical tips.
