Change is underway – thanks to a shifting perspective and evolving consumer sentiments, virgin resins are being surpassed by post-consumer recycled material (PCR). This move has implications across the entire plastic value chain, from polymer manufacturers to compounders/masterbatchers and converters. However, when compared to virgin resins, PCR feedstock has its own issues – such as being inherently variable and prone to contamination.

In this hour-long webinar, industry experts explore viable solutions, such as fingerprinting recycled resin feedstock by measuring polymer properties like crystallinity, viscosity and processing temperature. By doing so, you’ll discover how batch-to-batch variations in recycled resin composition affect thermoplastic processing. In addition, they’ll show how it is possible to harness the insights provided by thermal analysis and rheology data to take control of your processing conditions, resulting in the delivery of consistent product performance.

By the end of this webinar recording, you will have learned…

  • How to measure fundamental material properties like melting region, crystallinity and heat of fusion relevant to processing conditions
  • To quantify flow properties critical to injection moulding and extrusion processes
  • Ways to monitor the effects of thermal history on product quality, allowing you to take the relevant corrective measures
