Webinars, seminars address plastics processing and extrusion issues

Extrusion expert and PlasticsToday contributor Allan Griff has announced two webinars this month and face-to-face one-day seminars on extrusion fundamentals in Chicago, Los Angeles and Houston later this year.

A webinar on June 9, sponsored by SPE (Bethel, CT), will address plastics in the environment. “I will discuss the widespread negative public image of plastics, which has led to so many restrictive laws and a general feeling that plastics are somehow bad for us and for our environment,” explains Griff. He will explain how plastics, in fact, do more good than harm through lightweighting by requiring less fuel to transport goods, enabling sanitary practices in medical and packaging applications and optimizing agriculture. Griff also will cover the confusion surrounding phthalates, the 50-year history of the vinyl chloride danger, BPA, polystyrene foam products and bioplastics, specifically biosourced versus bioactive materials.

“Finally, we’ll discuss the underlying fear of science, in general,  and chemistry, in particular, as a challenge to our need to believe in the impossible,” adds Griff.

A second SPE-sponsored webinar devoted to testing incoming raw materials is scheduled for June 16. “We buy materials on specifications, but don’t always test what’s coming in, nor do we know the acceptable variation of those specifications,” says Griff. Noting that he respects and admires material suppliers—“I used to work for one,” he says—Griff nevertheless feels that it is necessary to test what we buy, especially when the prices are lower and/or the original source is unknown. This also holds for reuse of our own scrap and trim. 

The webinar will discuss properties such as viscosity and density, color, contamination, lubricity and bulk density and Griff will suggest tests, often inexpensive, to monitor them. Sampling and testing principles and the proper use of common additives also will be covered.

The cost for each webinar is $99 for SPE members and $150 for nonmembers. They will be recorded and made available to paid registrants for six weeks after the presentation dates. SPE members may have access to the archived webinars after these dates. 

In the fall, Griff will hit the road and bring his one-day practical seminar, "Introduction to Extrusion," to Chicago, Los Angeles and Houston. Topics include the ten (11) key principles of extrusion, plastics chemistry for non-chemists, a review of extrusion hardware, the limits to production rate, quality control of raw materials, simplified rheology, start-up and shut-down procedures and troubleshooting common extrusion problems. 

Seminar fees are $495 per individual and $250 for each additional attendee from the same company.

Griff also is available for in-house seminars and can modify the content, as needed. For more information about this or the fall seminars, e-mail him at [email protected].
