Webinar: Additive Blooming - Origins, Detection, and Control in Polymer Processing


Updated April 2023

Most polymers contain many non-polymeric components intended to stabilize, toughen, color and lubricate the final product. Certain classes of these additives are capable of migrating to the surface. This additive migration can create a surface that has a composition very different from the bulk of the polymer. If the manufacturing process includes an interface between the polymer and an adhesive or paint, or in the case of a medical device, contact with human tissues, additive migration to the surface (blooming) can have serious consequences. Blooming represents a form of contamination that can result in adhesive or paint failures or worse.

This webinar discusses:

  • The origins of blooming
  • Common additives that are subject to blooming
  • Strategies for detecting, controlling, and avoiding issues associated with blooming.
