DSC Interpretation Made Easy for Plastics Optimization

March 15, 2018, 11:00 AM EST
Presenters: Jeffrey Jansen

DSC is a very powerful and versatile tool. Insufficient interpretation skills prevent you from taking advantage of the additional information (material condition, propertie...) available for efficient optimization of your plastic material and prevention of premature failure. Join this course to:

Live Presentation: Preventing Plastic Part Failures (SPE Carolinas Section)

March 19, 2018
Presenter: Jeffrey Jansen

The best way to avoid plastic part failure is to understand the most common causes of failure. This presentation will cover topics essential to understanding plastic failure and present information regarding how and why plastics fail. By avoiding common mistakes it is possible to produce plastic parts that have a superior chance to perform successfully.

Based on having conducted over 1550 failure investigations, a number of the most common causes of plastic failure will be review in order to illustrate this point. These include excessive sharp corners, molded-in residual stress, insufficient drying of molding resin, improper material selection, time factors, and chemical contact.

This presentation will focus on practical techniques to avoid future failures. The participants will gain a better understanding why plastic components fail, and how to avoid future failures by applying the knowledge learned.

Environmental Stress Cracking of Plastics

March 21, 2018, 11:00 AM EST
Presenter: Jeffrey Jansen

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, and help prevent premature failure. Environmental stress cracking (ESC) is a phenomenon in which a plastic resin undergoes premature embrittlement and subsequent cracking due to the simultaneous and synergistic action of stress and contact with a chemical agent. ESC is a leading cause of plastic component failure, and a recent study suggests that 25% of plastic part failures are related to ESC.

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:

Polyethylene: Expert Advice on Formulation & Failure Analysis to Achieve Best Performances

March 29, 2018, 9:00 AM CT
Presenters: Jeffrey Jansen

Polyethylene resins are the largest volume plastic material used worldwide, approximately 80 million metric tons. In spite of a rather simple structure, polyethylene is a relatively diverse material used in a wide range of applications. One of the things that make polyethylene unique is the variation in structure, resulting different classes of polyethylene, including high density polyethylene (HDPE), low density polyethylene (LDPE), ultra high molecular weight polyethylene (UHMWPE), and cross-linked polyethylene (XLPE). Polyethylene is classified by a combination of crystallinity/density, chain branching, and molecular weight/melt flow rate. The various types of polyethylene are utilized in the manufacturing of products in numerous industries:

Part of the diversity of polyethylene is that it can be processed in many different ways, including injection molding, blow molding, extrusion, and thermoforming.

UV Effects on Plastic Materials

April 5, 2018, 12:00 AM CT
Presenters: Jeffrey Jansen

If you work with plastic components that include outdoor exposure, then "Ultraviolet (UV) Effects on Plastic Materials" will provide you with information that will enhance your understanding of the interaction between UV radiation-based weathering and plastic resins, and help prevent premature failure. Topics covered during this session 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.

The course will also include a review of the alternatives to protect plastic materials from UV degradation. These include resin additives and protective coatings.

Presenters: Jeffrey Jansen

Three different thermoplastic polyester materials were evaluated to investigate the connection between the structure of the materials and their properties. Three materials representing distinct characteristic structures were selected to contrast the results. The resins evaluated included polycarbonate, with carbonate ester functionality; poly(ethylene -co- 1,4-cyclohexanedimethylene terephthalate), a poly(ethylene terephthalate) copolymer; and poly(ethylene naphthalate), with two condensed aromatic rings. The characteristics tested as part of this work included tensile properties to illustrate the short-term mechanical attributes, glass transition temperatures to represent the thermal response of the materials, and creep modulus to demonstrate the time dependency.
