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 will explore viable solutions, such as fingerprinting recycled resin feedstock by measuring polymers properties like crystallinity, viscosity and processing temperature. By doing so, you can 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.

Watch this webinar to learn:

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