The SPE Library contains thousands of papers, presentations, journal briefs and recorded webinars from the best minds in the Plastics Industry. Spanning almost two decades, this collection of published research and development work in polymer science and plastics technology is a wealth of knowledge and information for anyone involved in plastics.
|How does craft beer relate to our industry? • Companies have the same equipment, but use it differently based on the products that their customer’s demand. • Both industries are very open and collaborative. People freely share their operational ideas and innovations. • Key characteristics are closely monitored in both industries. • Particle size distribution matters. It causes molding issues in roto, and prevents you from getting your grist into the mash in brewing. • The operational set-ups are dependent on product mix. • Both processes are hot and physically demanding. • Both industries have a limited number of raw materials, and it’s up to the designer to use those to create different and wonderful products. • Both industries have to innovate to succeed.|

This is a technical marketing presentation about "Mechanical Properties of Reinforced Compounds for Large Format Additive Manufacturing (LFAM)"
When designing plastic parts that are to be 3D printed, the designer must consider certain unique characteristics of the plastic printing process. These characteristics imply that different techniques must be used during design of 3D printed plastic parts than what might be used during design of injection molded plastic parts and design of 3D printed metal parts. This session will discuss some of the unique aspects of designing plastic parts for 3D printing as well as unique aspects of the preparation for printing these parts.
Cellulose nanocrystal (CNC) thermoplastic urethane (TPU) nanocomposites offer a wide range of unique thermal and mechanical properties. This paper focuses on solution mixing and melt processing considerations for producing cellulose nanocrystal (CNC) thermoplastic urethane nanocomposite filaments which can subsequently be printed using a fused filament fabrication (FFF) machine.
The case study will provide the roadmap as to how HP’s MJF technology will be used to manufacture components for manufacturing. This case study will go through the different phases of the process that enabled 3d Printed content for the next series of MJF 3d Printers. Including the steps of Assessment, Design, Economics, and manufacturing.
Multi Jet Fusion is new to the additive manufacturing industry, but the capabilities enable the process to be used in the manufacture of production quality components. This technical session will present a deep dive into the technology and illustrate how it achieves the value proposition and how to unlock value with the technology. Additionally, applications that are enables by Multi Jet Fusion will be discussed.
Fiber orientation can create layers with oriented fibers that behave as pseudo-plies, analogous to more conventional continuous fiber or fabric reinforced composites. Warp and distortion of several part geometries produced from carbon fiber composites made on a Stratasys FORTUS 450mc printer are analyzed as a function of the pseudo layup and structures used to fabricate the parts. Practical solutions for mitigating warping and balancing physical properties are proposed.
The application of linear low density polyethylene (LLDPE) in semiconductive medium voltage power cable strippable insulation shield (IS) is investigated in this work. Carbon black is mixed in the LLDPE alone and LLDPE/EVA blend in IS compounds for study. The critical performances of the IS compound, such as compatibility of carbon black, mechanical properties, strippable force to XLPE, electrical property, are briefly evaluated initially for the feasibility of LLDPE in such application. The results meet the basic requirement and indicate such possibility with cost benefit.
This paper deals with the behavior of thermoplastic melt, which is excited by oscillations via piezoelectric actuators. The experimental setup is designed to transmit vibrations directly into the melt. The result of this procedure is a reduced viscosity for two different thermoplastic resins of up to 23 %. Amplitude and melt temperature have little to no effect on viscosity reduction during oscillation.
We have investigated the flame retardant (anti-dripping properties) of a polycarbonate resin by using a dynamic mechanical analysis. A UV curable polycarbonate resin showed a strong rubbery plateau as a function of UV dosage and the amount of UV active end group. The average storage modulus is defined in the rubbery plateau region from 160 to 190°C with average storage modulus of 9 MPa being a threshold value to achieve optimum flame rating.
Die build-up negatively impacted the capacity of a compounding line for the production of a polyolefin-based wire and cable formulation. This paper discusses a root cause analysis performed on the die build-up defect, the identified solution, and the resulting economic impact.
While dynamic testing in torsional rheometers is a well known method, the use of axial or solid state DMA is often considered more of a thermal rather than a rheological technique. DMAs like the Mettler DMA 1+ allow the testing of materials from the solid state into the melt and from the uncured liquid state to a solid. This allows a fuller range of temperatures to be covered in one scan using the shear fixtures. Examples and applications will be discussed.

The current trend towards energy efficient commercial vehicles requires a substantial improvement in their aerodynamic performance. The development of a ducted fairing design for a Day Cab using computational fluid dynamics and scale wind tunnel evaluationis presented as well as the validation of the final design by means of a full scale prototype used for comparative testing with a commercial fairing in constant velocity track tests and highway coast down
There has never been a more exciting time to be in the Auto industry, with disruption and innovation occurring on many fronts. Electrification of the Powertrain, Autonomy, Regulation, and Connectivity are Megatrends impacting the future of mobility, and plastic materials play an important part in each of these large scale changes that will ultimately remake 'what' a light passenger vehicle is and does, and 'how' humans are transported in the future. This paper will touch on each of these trends and the potential impact on the Auto sector.
Thermoplastic Polyolefins (TPOs) have become very dominant materials among automotive plastics. Because of their versatility with formulation changes the TPOs are currently being used in all automotive applications. The presentation will cover how the TPOs were evolved and why the automotive applications are growing rapidly.
Scratch resistance has been issued in automotive industry, which is a measure of scratch on the plastic material for the interior and exterior of automotive. The effect of thermoplastic olefin (TPO) composition with various fillers and novel glass filler, which has high aspect ratio, on scratch resistance and mechanical properties was investigated in this study.
Core-Back Technology enabled a 1.9mm IP substrate to be molded then expanded to 4.0 mm . Resulting in less cost & weight while increased stiffness and low emissions.
