Plastics & the Environment: Dispelling Popular Myths With Scientific Facts

Chris DeArmitt, July 2020

In order to make wise decisions, we must start with facts. Unfortunately, plastics have been sentenced in the court of public opinion without facts or evidence. The public have turned against plastics based on nothing more than unsubstantiated social media posts and sensationalist journalism.

As a career scientist, I decided it was time to go look for the facts. It took over a year to collect and read more than 400 peer-reviewed scientific publications. I discovered that virtually everything the public believe today is utterly untrue. This talk distills down the science around waste, litter, degradation, microplastics and more. You will be shocked to discover what the science tells us. Plus will be given free access to The Plastics Paradox book which explains how today’s policies are harming rather than helping the environment and what we should be doing instead.

Developed for a Fortune 500 company who offered over $10,000 dollars, SPE members can access it for free. The first couple of chapter is available to the public at: plasticsparadox.com.

Impact Failure of Plastics

Jeffrey A. Jansen, June 2020

While in service, plastic materials are subjected to many different types of mechanical stress. One common type of stress that is typically severe on plastics is rapid impact loading. The rate at which loading is applied, otherwise known as the strain rate, is a very important factor in the performance of a plastic component. Impact, together with snap fit assembly, and rapid pressurization are the most common forms of rapid loading or high strain rate mechanisms.

The response of plastics to impact and the ability of a plastic part to withstand the stress through absorption of the applied energy is dependent on many aspects, including the material, design, processing and the service conditions.

Topics covered as part of this presentation will include:

• Failure Mechanism of Plastics
• Strain Rate as a Ductile-to-Brittle Transition
• Impact Failure
• Factors Effecting Impact Resistance
• Impact Testing
• Case Studies

Impact loads are among the most challenging stresses that plastic component designers and manufactures must deal with. In many cases impact stress is not adequately accounted for. In may cases this leads to unnecessary premature or unexpected failure.

Fundamentals of U.S. Patent Law

Dr. Steve Grossman, June 2020

This seminar will focus on fundamentals of U.S. patent law with applicability to medical plastics, medical devices and pharmaceutical technology.  Issues considered will include: (1) what is patentable subject matter; (2) pros/cons of provisional patent applications; (3) novelty and non-obviousness; (4) sufficiency of disclosure to enable an invention; (5) the importance of providing “reasonable certainty” in patent claims to optimize claim scope (some interesting recent cases);  (6) a primer on the U.S. first-to-file system; and (7) the relatively new “prior user rights” defense providing more security to trade secret holders.

Plastic Failures Associated with Metal Fasteners

Jeff Jansen, May 2020

The need to secure plastic components is prevalent in the manufacture of assemblies in many industries. Joining plastic components to other plastic parts or metal parts often involves the use of mechanical fasteners, such as screws, inserts, or rivets. The joining of plastic parts is inherently more complicated than assembling two metal components because of the fundamental differences in physical properties, including strength, chemical resistance and susceptibility to creep and stress relaxation. Case Studies will be presented to illustrate failures associated with the interaction between plastic components and metal fasteners. The presented cases will illustrate how the failure analysis process was used to identify the failure mechanism as well as the primary factors responsible for the failures. The cases depict representative failures involving varied designs and service conditions.

A MultiDrive Rheo-DMA Platform for Extended Polymer Analysis

Abhishek Shetty, March 2020

Dynamic mechanical analysis (DMA) is a well-established technique for characterizing mechanical properties of all kinds of materials, particularly polymers or polymer-based products such as thermoplastics, thermosets, elastomers, adhesives, paints and coatings, films and fibers, as well as composites. A new measuring device concept is introduced which combines an electronically commutated (EC) motor as rotational top drive and a moving magnet linear drive or another EC motor, as bottom drive to enable rheological measurements and DMA on one single device. The concept enables various modes of operation by using different combinations of the bottom drive. Besides working in the rheological modes such as separate motor transducer (SMT), combined motor transducer (CMT), counter-rotation and counter-oscillation the device is suitable to perform dynamic mechanical analysis in bending, tension, compression, and torsion. DMA can provide quantitative and qualitative data regarding:     Viscoelastic moduli and damping
    Material structure and morphology
    Relaxation behavior (Primary, secondary)
    Influence of fillers and fibers in polymers
    Crystallization/melting processes
    Curing behavior In this webinar, you will learn how DMA can be used to gain a better understanding of the viscoelastic and thermal properties of your material. The theoretical basics of DMA measurements will be covered along with the test methods and the information gained from those. Various DMA applications ranging from polymer plastics, rubbers to composites will be discussed and the flexibility and versatility of such a 2 in 1 device concept will be demonstrated for extended polymer characterization.

Failure Associated With Injection Molding

Jeff Jansen, December 2019

The injection molding process is one of the key characteristics that determines how a plastic part will perform in service. Manufacturers certainly attempt to avoid failure, but often unanticipated factors result in unexpected problems. The chances for a successful application can be significantly increased through preventative measures, including appropriate material selection, proper mold design, and process development. Even when appropriate actions are taken, failures can still occur. The evaluation of these failures provides an opportunity for learning. By understanding how and why a plastic component is failed, steps can be taken to prevent future occurrences. Case Studies will be presented to illustrate failures associated with the deficiencies from the injection molding process. The presented cases will illustrate how the failure analysis process was used to identify the failure mechanism as well as the primary factors responsible for the failures.

Managing Difficult People Without Becoming One of Them

Patricia Simpson, October 2019

Being an effective and positive communicator at work is vital to every role. When we work with other people, however, communication styles don’t always work well together. This webinar will share ideas about how to be a successful communicator as well as how to deal with people whose communication styles don’t always complement yours. While this webinar is not a ‘conflict management how-to,’ the communication etiquette tips shared will help make some of those situations easier. First setting a positive foundation can assist with making negative communication situations easier to handle. Additionally, learning how to provide a sincere apology without overdoing it - and communicating personal responsibility and credibility - can help calm impassioned interactions. In truth, we can’t change others…but we can manage ourselves and thus mitigate negative situations.

Understanding Failure Rate in Plastic Components

Jeff Jansen, September 2019

When a plastic part fails, a tough question is often asked, “Why are a limited number of parts failing?”. This is particularly true with seemingly random failures at significant, but low, failure rates. Two aspects are generally linked to such low failure rates, multiple factor concurrency and the statistical nature of plastic failures. Failure often only takes place when two or more factors take effect concurrently. Absent one of these factors, failure will not occur. Plastic resins and the associated forming processes produce parts with a statistical distribution of performance properties, such as strength and ductility. Likewise, environmental conditions, including stress and temperature, to which the resin is exposed through its life cycle is also a statistical distribution. Failure occurs when a portion of the distribution of stress on the parts exceeds a portion of the distribution of strength of the parts. This webinar will illustrate how the combination of multiple factor concurrency and the inherent statistical nature of plastic materials can result in seemingly random failures.

Meetings from Ordinary to Extraordinary

Paul Axtell, September 2019

Effective meetings are a competitive advantage for organizations. The ability to set up a conversation, manage the conversation, and wrap it up effectively is usually the missing piece in most organizations. Meetings continue to be a source of frustration—especially when people end up taking work home to make up for time lost in unproductive meetings. Make your meetings a welcome part of your week with this workshop on process skills, which can also expand your influence in the organization. While most people think that passion, knowledge, and drive are all they need to succeed, your meeting skills are what will set you apart.
