Influence of Gas-counter Pressure on the Foaming Behavior and the Cell Morphology of Flexible Polyurethane Foam
Daniel Schneider, Institute of Plastic Processing at RWTH Aachen University
Discontinuously produced polyurethane (PU) foams can be found in various applications and branches. Typically used blowing agents show significant economic or ecologic disadvantages. Using CO2 as a sustainable blowing agent displays different processing challenges. In this context the influence of gas-counter pressure, which is introduced in the cavity of the mold before injection, and of the CO2-amount on the foaming characteristics and the foam-morphology have been analyzed.

New Generation HDPE for Pressurized Applications – Beyond PE100
Jonathan Rabiei Tabriz, SABIC Petrochemicals
Polyethylene resins developed for pressure pipe applications has been existing in the market for close to 70 years. The development of resins has been moving forward with both technology advances and developing market requirements. This paper follows this development by introducing a new generation HDPE materials classified as PE112, as a step closer to the next major pressure class, PE125. SABIC® P6006AD pipe resin family, not only shows superior pressure resistance vs standard PE100 resins but also superior ESCR performance. The paper also presents a new class of HDPE resins with superior resistance to aggressive disinfectants, so called PE100RD. Performance data will be presented of SABIC® Vestolen A RELY 5933RD compared to standard PE100 resins under exposure to aggressive disinfecting media, such as Chlorine dioxide.

Jim DiVita, KEP Americas
Korea Engineering Plastics (KEP) expands its already robust line of technical polymers with the introduction of Kepital® H100, a new polyacetal homopolymer. Already a leading producer of polyacetal (POM) copolymers, KEP recognized the need for innovation in the homopolymer category. This is especially important since it has been nearly two decades since the industry last expanded homopolymer capacity. A global solutions provider focused on innovation, KEP is eager to serve those customers looking for best-in-class polyacetal homopolymers.

Super High Flow Valox for Connectors
Kenneth Thiel, SABIC
The high melt flow of polyesters allows the molding of small, intricate parts. PBT has grown well in past years in the electrical/electronics market. There is a trend towards thinner wall connectors to fully utilize space on printed circuit boards and as new designs have emerged for computers and telecommunication devices. While still maintaining heat and mechanical performance of the application.

Volumetric to Gravimetric Conversion
Riley Wittmann, UW Stout
This capstone project consists of making a gravimetric feeder from a volumetric feeder with a speed-controlled screw. A gravimetric feeder starve-feeds material into an extruder at a constant weight per hour. A lot of extrusion companies use gravimetric feeders because it saves them a lot of money on scrap from inconsistent lines of filament. It also uses Proportional Integral Derivative (PID) controlling to monitor the weight loss and counteracts any feeding inefficiencies. Without using PID and instead using a set speed control, the screw might not feed a constant amount of material. The PID will be implemented into the system using C++ language in the Arduino software. The project will be completed using a starve-feeding hopper, a 165-lb. capacity bench scale, an Arduino Uno kit, a motor shield, and an RS-232 converter.

Stylight – New Material Solution for Lightweight Design
Brian Haggart, INEOS Styrolution
A newly developed material known as Stylight has been created for design flexibility and lightweighting solutions. Stylight incorporates carbon and glass fibers in an SAN (amorphous polymer) matrix. The SAN matrix allows for a smoother “Class A” finish than traditional thermoformable composite sheets that are normally used hidden structural applications. The glass and carbon fiber also help provide a rigid and tough backbone for structural applications as well. Stylight also provides design flexibility and is able to be painted or covered in decorative film or used with carbon weave pattern.
