Reaction Injection Molding (RIM) – Low-Quantity Injection Molding for the Life-Sciences Industry

Presented by: Ken Schweitz & Doug Culbertson, Premold Corporation, January 20, 2010
$99.00
Description:
The Reaction Injection Molding (RIM) process economically produces low-quantity injection-molded parts for the life-sciences industry. Medium-sized to large enclosures and housings can be produced from low-cost tooling. Designing for the RIM process is easier than designing injection-molded parts because the RIM process allows more design freedom. The RIM process is relatively new and perhaps the least understood and most underutilized of the low-pressure processes for plastic parts. Recent developments in resins have allowed this high-value process to compete with injection molding.

Ultraviolet (UV) Effects on Plastic Materials

Presented by: Jeffrey A. Jansen, Stork Technimet, January 27, 2010
$99.00
Description:
If you work with plastic components that are subject to outdoor exposure, this webinar will enhance your understanding of the interaction between UV radiation-based weathering and plastic resins, and help you prevent the components’ premature failure. Topics covered include an introduction to UV degradation and an explanation of the failure mechanism characteristic of UV radiation/plastic interaction. Case studies associated with UV radiation exposure will be presented.

Plastic Conversion Processes Selecting the Correct Process for Your Design, Parts 1 & 2

Presented by: Eric Cybulski, 3M, February 3 & February 10, 2010
$149.00
Description:
Overview

The Promise of Bioplastics – State of the Technology, Feedstock, and Commercial Landscape

Presented by: Ramani Narayan, Michigan State University, February 11, 2010
$99.00
Description:
Biobased plastics offer the value proposition of a reduced carbon footprint. Biodegradability offers an environmentally responsible option for products at the end of their lifecycles. This webinar reviews this value proposition and presents an approach to positioning and communicating the value proposition with real-world product examples. Material and process carbon footprint analysis and LCA (lifecycle assessment) tools will be discussed.

Breakthrough Inventions in Polymer Extrusion and Compounding Processes, Polymer Blends and the Role of Fundamental Mechanisms

Presented by: Chi-Kai Shih, Chi-Kai Shih LLC, December 9, 2009
$99.00
Description:
Vast improvements in polymer extrusion have been achieved through breakthrough innovations and inventions in fundamental mechanisms, machinery, screw and barrel design, functional operations, monitoring, and control. Discoveries in the fundamental extrusion mechanism played a major role in these inventions. Over the years, these discoveries helped identify the deficiencies existing in the original extruders, screw designs, and compounding processes, and hence initiated a variety of breakthroughs leading to the highly productive processes of today.

Pricing for Profitability - Activity-Based Pricing for Competitive Advantage

Presented by: John Daly, Executive Education, Inc. and Craig S. Carrel, Team 1 Plastics, November 5, 2009
$99.00
Description:

    John Daly will present the first section, which will focus on the theory of activity-based pricing.

Morphology and Properties of Exfoliated Graphene/Thermoplastic Nanocomposites

Presented by: Chris Macosko, University of Minnesota, November 18, 2009
$99.00
Description:
Graphite has attracted attention as a reinforcement for polymers because of its ability to modify electrical conductivity and the mechanical and gas-barrier properties of host polymers, and its potentially lower cost than carbon nanotubes. If graphite can be exfoliated into atomically thin graphene sheets, it is possible to achieve the highest property enhancements at low loadings. However, exfoliation of graphite via conventional composite-manufacturing strategies is challenging.

Review on Mechanism and Quantification of Polyethylene Discoloration

Presented by: Dr. Thoi Ho, December 3, 2009
$99.00
Description:
The discoloration of polyolefins has been extensively studied. The key mechanism of discoloration includes oxidation of polyethylene and/or oxidation of hindered phenolics used as antioxidants by oxygen or nitroxide pollutants from hydrocarbon combustion, e.g., internal combustion engines, or methane- or propane-fired heating systems.

Elimination of Defects From Injection-Molded Parts via Screw Modifications

Presented by: Mark A. Spalding, The Dow Chemical Company, December 2, 2009
$99.00
Description:
Many defects in injection-molded parts are caused by improper screw designs. Elimination of defects and optimization of the process can often be achieved via simple modifications to the screw. In a case study described in this presentation, a splay defect was caused by a screw with a low compression ratio, regions where resin can stagnate and degrade, and a limited melting capacity. Modifying the screw eliminated the defects, decreased the cycle time by 8%, and increased the plant capacity by 14%.

A Formulation Study of Long-Fiber Thermoplastic Polypropylene (Part 2): The Effects of Coupling Agent Type and Properties

Presented by: Creig Bowland, PPG Industries, October 21, 2009
$99.00
Description:
The relationship between the resin and fiber properties in polypropylene long-fiber thermoplastics is further analyzed in the second part of this work. The properties of the maleic anhydride–grafted polypropylene additives (coupling agents) are studied, and correlations between the maleic anhydride content, melt flow, and base polymer are presented. Various samples of polypropylene long-fiber thermoplastic pellets (PP GLFT and PP DLFT) were compounded with various coupling agents. The materials were then molded and tested for normal mechanical properties.
