Raber Inoubli, July 2021
Part 2 of the All Things PVC Workshop series. The speaker will review the basics of core-shell chemistry focusing on acrylic technology and its advantages for mechanical property improvement and weatherability in PVC formulating. Core principles of mechanical property improvement via stress concentrators for PVC matrices and formulations will be presented. In addition to rheology and mechanical property enhancement via acrylic chemistry, the presentation will also provide perspective on choosing the best impact modifier based on specific formulation needs or application types where standards vary based on the final needs of the vinyl building product, for example. The talk will follow-up on the principles covered in the introduction to PVC Gelation and Formulation.
Introduction to PVC Gelation and Formulation
Kevin Yocca, June 2021
Part 1 of the All Things PVC Workshop series. While introducing the general properties of PVC suspension resin that make it unique for processors, the speaker will discuss why PVC formulations can get complicated and present so many options for optimized processing and customization by application. The focus will mostly revolve around suspension PVC for rigid vinyl applications, but touch upon some basics of plasticized or flexible vinyl as well. The speaker will talk about gelation theory, why lubricant balance is important and how different additives can influence rheology, mechanical performance, and even weatherability. The talk will be an introduction to PVC overall but also a lead-in for the next workshop, an introduction to acrylic impact modifiers and core-shell modifier chemistry.
Polypropylene: Commodity Resin, I Don't Think So
Jeffrey A. Jansen, June 2021
Polypropylene is often referred to as a “commodity resin”, however, is this really the case? Polypropylene is a versatile thermoplastic that can be processed through a variety of processing techniques. It is utilized in a wide range of applications, including packaging, automotive, infrastructure, appliances, healthcare, and electrical. Its wide use is based upon several key strengths, including:
  • Good chemical resistance
  • Good electrical insulation properties
  • Flexural strength and modulus
  • Relatively low coefficient of friction
  • Readily available and relatively inexpensive
The implication of the interchangeability of polypropylene resins does a disservice to the complexity of this material and the plastic industry in general. The properties of polypropylene are highly dependent on molecular weight and molecular weight distribution, crystallinity, type and proportion of comonomer and the tacticity. Hopefully, at the conclusion of the webinar, attendees will
  • Gain an understanding of the general properties of polypropylene.
  • Have more insight into how the molecular structure of polypropylene determines its performance properties.
  • Appreciate the diversity of polypropylene.

Fractography of Glass Reinforced Plastics
Jeff Jansen, April 2021
The goal of a failure analysis is to identify the mechanism and cause of the component failure - to distinguish how and why the part broke. A fractographic examination is an essential part of this investigation, particularly in identifying the failure mode. Cracking occurs as a stress relief mechanism as a response to the exertion of stresses on a component. Glass fiber reinforced plastics offer enhanced mechanical properties, particularly strength and stiffness over unfilled materials. Their use is widespread in a wide variety of applications where mechanical integrity is essential. However, fractographic evaluation of these materials often presents a challenge due to the confounding effect of the fibers. The fibers can obscure the fracture surface features arising from:
  • Type of material and formulation constituents;
  • Type of applied forces (tensile, compression, shear);
  • Magnitude of forces;
  • Frequency of forces (continuous, intermittent, rapidly applied);
  • Environmental effects (temperature, presence of chemical).
This presentation will explore the challenges unique to glass fiber reinforced materials and techniques that can be used to gain the maximum information from these fracture surfaces.

Thermal Analysis of Plastics
Jeffrey A. Jansen, March 2021
Thermal analysis is an important group of tests used in the analysis of plastics and other polymeric materials. It consists of a family of well-established techniques that evaluate material properties as they change with temperature, time, and ambient environment under conditions of thermal programming. The results of thermal analysis tests provide qualitative and quantitative information about the material being evaluated. In particular, this information is important to address plastic failures or in characterization of the material composition and physical properties. The upcoming webinar on thermal analysis will introduce the four primary techniques:
  • Differential Scanning Calorimetry (DSC)
  • Thermogravimetric Analysis (TGA)
  • Thermomechancial Analysis (TMA)
  • Dynamic Mechanical Analysis (DMA)
The webinar is designed to introduce the techniques to the attendees so that they may get a better understanding of how the techniques can be used to evaluate plastic materials and solve problems. No single thermal analysis technique is best suited universally, but together they provide essential data for the characterization of plastics materials. This presentation will review thermal analysis techniques and their application to plastic problem solving through case studies. The webinar will be a practical treatment of the techniques, and the focus will be on how the techniques can be utilized to better understand polymeric materials. At the end of this presentation you will:
  • Gain insight into the different types of thermal analysis techniques
  • Recognize which technique is best suited to obtain the information you need
  • Understand how thermal analysis can be used to characterize the composition and properties of plastic

Environmental Stress Cracking
Jeffrey A. Jansen, February 2021
Environmental stress cracking (ESC) is the leading cause of plastic component failure, and a recent study suggests that 25% of plastic part failures are related to ESC. If you deal with plastic components, then “Environmental Stress Cracking of Plastics” will provide you with information that will enhance your understanding of the interaction between chemicals and plastic resins, with the goal of preventing part failure. ESC is a solvent-induced failure mode in which a plastics crack through contact with a chemical agent while under stress. The webinar will be presented from a practical viewpoint with actual case studies to illustrate the ESC mechanism and explain plastic performance. Topics covered during this session include:
  • Introduction to ESC
  • How plastics fail
  • Explanation of the ESC failure mechanism
  • Generalizations related to chemical interaction with plastics
  • ESC resistance testing used to evaluate plastic/chemical compatibility
  • Case Illustrations of some common solvent-based failure modes
At the end of this presentation you will:
  • Have a better understanding how chemicals effect plastic components.
  • Recognize potential situations where ESC failure could occur in your parts.
  • Be able to design a chemical resistance program to evaluate plastic/chemical combinations.

The Consequences of Ductile-To-Brittle Transitions in Plastics
Jeffrey A. Jansen, December 2020
Thermoplastic resins are utilized in many applications because of their unique property set, including their ductile response to applied stress. This ductility is associated with the viscoelastic nature of polymers and is attributed to their unique molecular structure. In spite of that inherent ductility, most plastic components fail through one of the many brittle fracture modes. Experience through conducting thousands of plastic component failure analyses has shown that less than 5% were associated with ductile overload. The remainder represent brittle fractures of normally ductile materials. Thus, within evaluations of plastic component failures, the focus of the investigation frequently turns to identifying the nature of the ductile to brittle transition. This relatively brittle response to stress is evident through the examination and characterization of the fracture surface morphology. There are numerous factors, associated with material, processing, design, and service conditions that influence a ductile-to-brittle transition within plastic materials. These include:
  • Temperature
  • Stress Concentration
  • Chemical Contact
  • Molecular Weight
  • Degradation
  • Filler Content
  • Contamination
  • Poor Fusion
  • Strain Rate
  • Time Under Load
  • Crystallinity
  • Plasticizer Content
Taking out the Trash, Plastics Design for the End-of-Life
Eric Larson, December 2020
Nothing lasts forever. Great products might not last forever, but they usually last a long time. But no matter how great the product is, there will come a point in time where a thing no longer has any value. It then becomes waste. To be thrown in the trash. And then what? How do you design a product to account for its expected end of life? Or an unexpected end? How do you evaluate materials based on what happens at their end of life? What tools are there? How to use them? What’s next? For plastics, and for the industry.
