Filtration of Post-Consumer Recycled Material

The addition of post-consumer recycled materials poses challenges for high quality extruded material. Post-consumer recycled feedstock can contain various contaminates and unpredictable molecular weight distributions which can result in increases in black specks and gels in high quality film and blow molded applications.

Polymer lines equipped with melt filtration can reduce and eliminate much of these defects, however on-line filter life can become problematic as the media will begin to plug at a faster rate. Cleaning melt filtration systems also pose challenges due to the ever-changing additives contained in post-consumer recycled feedstock.

At Carolina Filters, we are equipped with state-of-the-art technologies which can efficiently remove these various unknown organic and inorganic materials which become embedded in the filter media.
