Simplified Rheology for the Masses: A Technical Discussion

This webinar discusses the importance of plastic rheological equipment on today’s processors. Attendees will learn about market drivers, the science behind melt flow index determined at the extruder, and how specific polymer parameters developed in the laboratory can be measured and saved during a full production run.

Date: September 14, 2017
Time: 10 AM EDT (7 AM PDT)
Duration: 1 hour

Simplified Rheology for the Masses: A Technical Discussion expands on the need for correlation between the specifications developed in the laboratory and the 24/7 validation of these through the entire production run.

Polymers producers today must balance between:

  • The variation in polymer specifications coming from different suppliers
  • The need to increase production output and process efficiency
  • The complications of using reprocessed material to meet the corporate sustainability goals of their organization, utilize the scrap material from their production line, or introduce regrind from other sources for economic advantage

The concern with each of these initiatives is how focusing on one item over another might affect the quality of the part being produced. Historically this concern was reduced by a combination of the reliance on production veterans who learned through experience and the facility's quality control personnel running back and forth from the onsite laboratory verifying if the process is stable at specified time intervals.

In this webinar, we will focus on technical aspects of correlating laboratory measurements with full production runs. We will discuss how parameters change between laboratory standards and production and how advanced equipment today can adjust for these differences. We will also go through the simplicity and ease of use of today's next-generation measurement tools and how they allow every employee to understand whether or not their material is in specification throughout the production run.

Our goal is to make a "Window into the Process" for every size processor who utilizes polymer. We are driven to make rheology simple and improve the processors' quality and profitability.

Key Take-Aways

  • Learn how melt flow index is determined directly on an extruder
  • Discover how to verify your melt flow index
  • Understand the techniques to correlating melt flow index measurements to laboratory standards
  • Learn why there is now a market need for rheologic measurement based on 3 pillars-1) recycled content/sustainability (impact of n +x material in process), 2) reshoring (impact of cost manufacturing), 3) shale play (polymerization of the US): higher quality levels to drive profit and limit liability
  • Understand the fundamentals and specifics into product features and how it ties into market trends
