M5 Electrical and Electronics (Monday, April 22, in Room 231)
• 8:30 a.m. - “Ultra-high Flow Liquid Crystal Polymer” by Young Kim
A new flow improvement technology (FIT) including reactive extrusion and Ticona’s proprietary compounding technology enables a high flow liquid crystal polymer (LCP) with lower warpage. LCP polymer chain and its molecular weight distribution were tailored via reactive extrusion, while filler length was also controlled via the compounding technology. As a result, this technology makes it possible to improve product flowability, warpage, surface smoothness, and weldline strength for electrical and electronic devices.
• 10 a.m. - “New PCT Compound for LED Reflector Resin” by Bing Lu
Light-emitting diodes (LED), as a new light source, are being used more and more as display backlight and general lighting. Due to the increase of brightness and electrical current of LED packaging (PKG), there are demanding requirements of LED reflector resins on heat and light stability. A high performance polyester poly (1,4-cyclohexylenedimethylene terephthalate) (PCT) compound has outstanding reflectance stability under heat and light, enabling medium power LED PKGs for applications such as backlight in LCD televisions. In this paper, a new PCT compound is discussed in detail in the context of a LED reflector resin, and performance compared with high temperature polyamide compounds. The processing conditions for injection molding are also discussed.
M15 Polymer Modifiers Additives (Monday, April 22, in Room 202)
• 9:30 a.m. - “Improved Impact-Modified Polyoxymethylene Co-Polymers for use in Small Off-Road Engine (SORE) Gas Tank Applications” by George Zollos
Ticona has developed a new family of impact-modified polyoxymethylene (POM) co-polymers that demonstrate a combination of improved permeation resistance, cold temperature impact strength, and melt strength that make them suitable for use in the small off-road engine (SORE) gas tank sector. The unique properties of the new products have been achieved through the modification of the polymer backbone, along with the use of a specific coupling technology. The new grades provide a monolayer tank solution with enhanced permeation resistance and impact strength for a variety of injection molding and blow molding small off road fuel tank applications.
M16 Product Design and Development (Monday, April 22, in Room 251)
• 9 a.m. - “Vandar® High Impact Strength Polyester for Sporting Goods” by Mukul Kaushik
Vandar 2100 is an impact modified engineering thermoplastic resin developed to deliver consistent performance over a wide range of temperature and humidity conditions, primarily in injection molded articles. Vandar 2100 provides outstanding ductility and stiffness combined with the excellent chemical and environmental resistance properties of polyesters. The unreinforced and higher flexibility Vandar grades fill the property gap between standard thermoplastic polyesters and elastomers. These plastics are easy to process including by injection molding and retain their impact strength down to -30 °C.
M22 Color & Appearance (Monday, April 22, in Room 203)
• 2:30 p.m. - “High Temperature Aesthetic Grade Liquid Crystal Polymers for Consumer Applications: Not Just For Connectors Anymore” by Mark Tyler
For many years the use of high flowing engineered resins, such as Liquid Crystal Polymer (LCP), have been used for very detailed and intricate parts in the electronics and connector industries where function and performance far outweigh any need for coloristic attributes. Today we find the uses of such resins extending out to more visible consumer products that need the performance and functionality of the LCP with the additional demand of excellent aesthetics. This paper looks to show where the coloring of LCP and the producing of aesthetically pleasing parts has brought LCP’s from behind the scenes to center stage for the consumer products industry.
• 3 p.m. - “Low Gloss, Low Emission UV Stabilized Polyacetal Copolymer (POM)” by Bruce Mulholland
Automotive OEMs have increasingly become more interested in monitoring cabin air quality inside the vehicle. This leads to the need for further understanding and testing of emissions from the various materials including plastic parts. In addition, styling trends for automotive interiors continue to demand low gloss appearances. This paper explores how both demanding requirements can be met through the development of a low gloss, low emission POM material.
M24 Electrical and Electronics (Monday, April 22, in Room 231)
• 1:30 p.m. - “Laser Direct Structuring LCP for Mobile Antenna Applications” by Paul Yung
The rapid growth and global demand for wireless communication and increasing need for more functionality in smart phones have created a need for advanced engineering resin to meet new antenna requirements for mobile devices. This paper discusses performance of new laser direct structuring LCP grades and developmental grades with improved mechanical, thermal properties and dielectric properties engineered to meet new challenges of increased functionality and reduction in antenna size.
• 4 p.m. - Halogen Free Polyphenylene Sulfide for Consumer Electronics Applications by Rong Luo
The recent push for environmentally friendly halogen-free products has resulted in significant changes in the of polymer materials used in consumer electronics industry. A series of halogen free polyphenylene sulfide (PPS) products were developed to enable consumer electronics original equipment manufacturers and their suppliers to design and make products that will comply with halogen-free industry standards. These halogen free PPS products offer inherent flame retardancy (UL-94 V0), high flow suitable for small connectors, and high dimensional stability for metal over molding parts without loss of superior mechanical properties.
T25 Engineering Properties & Structures (Tuesday, April 23, in Room 204)
• 2 p.m. - “Integrated Anisotropic Simulation for Components Made from Glass Fiber Reinforced Thermoplastics” by Ulrich Mohr-Matuschek
Designing components made from glass fiber reinforced thermoplastics is not trivial since the fibers are inclusions in the matrix material which are specifically oriented in the mold filling phase during manufacturing through injection molding technology. This leads to, first, non-uniform and anisotropic shrinkage during and after the manufacturing process and, secondly, to a complex mechanical part behavior which cannot easily be predicted. Simulation techniques such as finite element analyses are well established and can effectively support the part design process but in many cases calculate the mechanical behavior of a component under external load by means of isotropic material models. The quality of the simulation results can be significantly improved if the local fiber orientations are taken into account. This is possible when a mold filling simulation is done upfront and the resulting local fiber orientation tensors are mapped to the structural analysis model and non-linear and anisotropic material models are generated locally in this FEA model. This analysis process and a practical application of the integrated approach are presented.
W6 Engineering Properties & Structure (Wednesday, April 24, in Room 205)
• 10:30 a.m. - “Plasticized Polyoxymethylene Performance in Fuels” by Jeremy Klug
Polyoxymethylene (POM) or polyacetal is an engineering thermoplastic resin that has been used for the past 50 years, primarily in injection molded articles. POM’s benefit is derived from its strength, stiffness, toughness, lubricity and inherent chemical resistance. This combination of properties has made standard POM a preferred material for applications involving fuel exposure - both in gasoline and diesel fuels. An innovative development has led to the introduction of plasticized POM, a material that has substantially increased flexibility and improved low-temperature performance versus standard POM. This paper details the properties of this new material and explores the performance of extruded tubing in different fuels.
Poster Sessions (Tuesday, April 23, 4 to 6 p.m.)
• “Innovative Polyphenylene Sulfide Material Tailored for Robotic Manipulated Blow Molding” by Ke Feng
A new technology has been developed to enable high tensile elongation of glass filled Polyphenylene Sulfide (PPS) materials at blow molding processing temperature. This technology enables engineers to tailor Fortron® PPS materials for different blow molding processes. Factors such as melt strength, impact strength, and manipulation capability could all be designed. A lab scale test has also been developed to well simulate any blow molding process. As the results of the material and testing development, a first-ever robotic manipulated 3D blow molding (RMBM) production run of ducts of very complex shape has been successful.
