Knowledge-Based Product Planning And Designing Of Injection-Molded Parts
This paper presents a procedure for an integrated design process regarding injection-molded parts. The support of the designer occurs from a knowledge-based production process and material selection, throughout the designing to a rheological part optimization. Techniques of the model-based systems engineering (MBSE) were used for the acquisition of requirements as well as for the development of this supporting system. For validation, selected methods are implemented and tested in a CAD-system.
Influence Of Gas-Counter Pressure On The Foaming Behavior And The Cell Morphology Of Flexible Polyurethane Foam
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.

Improve The Performance Of Your Retort Flexible Film
In this presentation UBE will talk about the challenges of using flexible barrier films replacing traditional retort packaging and the research done to develop the right structuctures and Nylon materials to overcome these challenges.
Biopolymer Compounds For Applications Requiring Marine Degradation
The development of a biopolymer netting for the establishment of new oyster beds in intercoastal waterways is described. The netting secures the growing oysters for 18 months before biodegrading to allow the oyster bed to grow. The establishment of multiple beds will improve the water clarity and promote the growth of seagrass.
Schulamid High Performance Nylon For Fuel System Applications
Schulamid 612 compounds have low moisture absorption, good chemical resistance, and no oligomers extractions comparing nylon 12. They are suitable for fuel system applications and are good alternatives to nylon 12 compounds. This presentation describes Schulamid 612 compounds portfolio and application examples.
Advances In Wear And Friction Solutions
This presentation reviews some of the basic approaches to improving wear and friction performance in thermoplastic compounds and introduces some newer ideas in non-halogenated wear compounds.
Accelerated Weathering Insights Into Asa Polymer Uv Resistance: Xenon Vs Quv Vs Florida And Arizona
This presentation compares the differences in color and gloss retention between QUV, Xenon, Florida and Arizona testing for 4 different Acrylate-Styrene-Acrylonitrile (ASA) polymers in white, almond and black colors. The results show the similarities and differences between the accelerated weathering test methods versus Florida and Arizona four-year test results leading into a discussion of performance lifetime predictability for the ASA materials studied.
Xenoy™ ENH2900 For High Chemical Resistance & Non-Br/CL FR Applications
SABIC XENOY ENH2900 resin provides a unique value proposition to meet application requirement of excellent chemical resistance and non-Br/Cl flame retardant.
Cooling-Free Valve Gating
Cooling-free pneumatic valve gate hot runners offer all the advantages of air actuation without the limitations associated with water cooling, hydraulic systems or electric actuators. New products like Rheo-Pro® iVG™ internal valve gate nozzles and Rheo-Pro® Black Box™ actuators are ideal for all valve gate hot runner applications, including high-temperature and cleanroom molding. These products perform under even the most extreme operating conditions by doing away with elastomeric seals, lubricants, and cooling. This new technology represents the future of automated, high performance injection molding.
Sabic Thermocomp™ High Modulus Ductile (Hmd) Portfolio
SABI HMD Portfolio Helps Customer Achieve Challenged Structural Design by providing high ductility, long term aging and dimensional stability.
Enhancement Of Protective Packaging Films With Cyclic Olefin Copolymers (Coc)
Cyclic olefin copolymers (COC) provide film manufacturers and converters with an opportunity to create thin, stiff, and high barrier protective packaging products. Protective packaging is an excellent illustrative application to showcase COC as effective and efficient polyethylene modifier. Key COC performance benefits include low nitrogen and water permeability, higher stiffness, lower tear resistance and broad heat sealing window.
The New Discovery DMA850 From Ta Instruments
TA Instruments is the world leader in rheology and thermal instruments. One of our thermal/rheology instruments is the dynamic mechanical analyzer (DMA). For several years, the Q800 DMA has been the leader among DMA instruments, but, in late 2017, TA Instruments introduced the new Discovery DMA850 as the next generation DMA. The capabilities of this instrument, along with a comparison of its performance against the Q800 DMA, will be presented.
