Plastic Datasheets: What They Do and Don't Tell Us
UL Prospector lists tens of thousands of different plastic resins. When tasked with material selection, 99% of us turn to the typical property data sheet. What are the issues with the single point numbers listed on these datasheets? Why does sole reliance on this information often lead to failed product? What should we be doing instead? Selecting the proper material for an application requires the right data. While plastic project have evolved over the past 50 years, the data we are given has not evolved. This webinar will present the deficiencies of the information presented on plastic data sheets, and suggest what is really needed.

Advanced Material Characterization Performing Rheological Investigations and Dynamic Mechanical Analysis with a Multidrive System
A new measuring device concept is introduced which combines an electronically commutated (EC) motor as a rotational top drive and a moving magnet linear drive or another rotational EC motor, as bottom drive to enable rheological measurements and dynamic mechanical analysis (DMA) on one single device.
The concept enables various modes of operation by using different combinations of the bottom drive. Three different testing modes can be realized when using the upper rotational EC motor and additionally a second rotational EC motor as the bottom drive. While the use of the upper EC motor allows one to perform measurements in combined motor transducer (CMT) mode, the use of both EC motors allows one to work in the separate motor transducer (SMT) mode and the counter movement mode on one device. CMT mode not only allows all tests and options a single drive rheometer can do but advanced powder rheology characterization in the fluidized dynamic state through the use of a classical pressure drop device attached to the rheometer are also possible. A ring shear cell attached to the rheometer in CMT mode allows one to do quasi-static characterization of granular materials at elevated temperatures and humidities. In the separate motor transducer (SMT) mode the bottom motor acts as the actuator and the top motor acts as the torque transducer.
A SMT mode has advantages in sensitivity under certain measurement conditions and allows the use of special tools such as a cone-partitioned-plate (CPP), which enables measurements with edge fracture prone samples, extended frequency sweeps with soft materials such as pressure sensitive adhesives where inertia of the measuring drive can effect results etc., In counter movement mode both motors rotate or oscillate in opposite directions which enables the creation of a stagnation plane in the sheared sample which could be beneficial for investigation of Taylor-Couette instabilities or extending the range of shear rates for high shear rheology applications or for rheo-microscopy, since the structures under investigation are not moving out of the field of view when shear is applied. In addition, combining the upper rotational motor with a linear drive in the bottom permits one to apply force and deflections in the axial direction.
This is suitable to perform dynamic mechanical analysis in bending, tension, compression, and torsion. DMA in tension by the linear drive and DMA in torsion by using the upper rotational drive are possible on the same specimen which allows one to extract the Poisson’s ratio of the material. In this talk benefits of having such a modular device configuration in different modes will be showcased via different application testing examples ranging from liquids, solids to granular materials.
Introduction to PVC Gelation and Formulation
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.

Fractography of Glass Reinforced Plastics
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:
Less is More: How to Maximize Energy Savings in Plastics Processing - Part 2
This is the second part of a two-part webinar.
This webinar will address behavioral and organizational approaches to industrial energy management. Josh will explain how manufacturing companies can implement energy programs, both through proven best practices and through local and regional utility funding programs.
Thermal Analysis of Plastics
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:
Less is More: How to Maximize Energy Savings in Plastics Processing - Part 1
Wasted energy is wasted profit. In these webinars, plastics engineers, plant managers, and financial managers will learn about the typical opportunities to save energy at plastics plants. In the first webinar, Josh Bachman and Pamela BIrkel will share energy savings opportunities that have been uncovered over the years. They will also share case studies of successful projects, many of which were funded by the local utility.
Environmental Stress Cracking
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:
