Semiconductive LLDPE Power Cable Insulation Shield
Jason Zhang, May 2018
The application of linear low density polyethylene (LLDPE) in semiconductive medium voltage power cable strippable insulation shield (IS) is investigated in this work. Carbon black is mixed in the LLDPE alone and LLDPE/EVA blend in IS compounds for study. The critical performances of the IS compound, such as compatibility of carbon black, mechanical properties, strippable force to XLPE, electrical property, are briefly evaluated initially for the feasibility of LLDPE in such application. The results meet the basic requirement and indicate such possibility with cost benefit.
Nylon 12/PMMA/San Alloys For Translucent Medical Catheters
Timothy Largier, May 2018
A Nylon 12 (PA12) alloy with polymethyl methacrylate (PMMA), styrene acrylonitrile (SAN), and styrene maleic anhydride (SMA) was optimized to increase flexural modulus while maintaining translucency. It was found that the optimal PMMA/SAN ratio to reduce haze in PA12 is 68.5/31.5. This allowed for the blend system to maintain translucency at all loadings of PA12. Mechanical testing was performed revealing that the flexural modulus was improved from the base resin from 154,915psi to 301,658 psi. Tubing samples that were produced as prototype catheters are robust, translucent, and flexible.
Influence Of Oscillating Surfaces On The Rheological Behavior Of Thermoplastic Melt
Julius Geis, May 2018
This paper deals with the behavior of thermoplastic melt, which is excited by oscillations via piezoelectric actuators. The experimental setup is designed to transmit vibrations directly into the melt. The result of this procedure is a reduced viscosity for two different thermoplastic resins of up to 23 %. Amplitude and melt temperature have little to no effect on viscosity reduction during oscillation.
Rheology As A Tool To Understand Anti-Drip Properties In Flame Retardant Polycarbonate Resins
Manojkumar Chellamuthu, May 2018
We have investigated the flame retardant (anti-dripping properties) of a polycarbonate resin by using a dynamic mechanical analysis. A UV curable polycarbonate resin showed a strong rubbery plateau as a function of UV dosage and the amount of UV active end group. The average storage modulus is defined in the rubbery plateau region from 160 to 190°C with average storage modulus of 9 MPa being a threshold value to achieve optimum flame rating.
Root Cause Analysis Of Polyolefin-Based Wire And Cable Formulation Die Build-Up
Kurt Koppi, May 2018
Die build-up negatively impacted the capacity of a compounding line for the production of a polyolefin-based wire and cable formulation. This paper discusses a root cause analysis performed on the die build-up defect, the identified solution, and the resulting economic impact.
DMA – The Other Side Of Rheology
Kevin Menard, May 2018
While dynamic testing in torsional rheometers is a well known method, the use of axial or solid state DMA is often considered more of a thermal rather than a rheological technique. DMAs like the Mettler DMA 1+ allow the testing of materials from the solid state into the melt and from the uncured liquid state to a solid. This allows a fuller range of temperatures to be covered in one scan using the shear fixtures. Examples and applications will be discussed.

The development of a ducted fairing design for a Day Cab using computational fluid dynamics and scale wind tunnel evaluationis presented as well as the validation of the final design by means of a full scale prototype used for comparative testing with a commercial fairing in constant velocity track tests and highway coast down
Intelligent Automotive Design With Plastics
Michael Ruby, May 2018
There has never been a more exciting time to be in the Auto industry, with disruption and innovation occurring on many fronts. Electrification of the Powertrain, Autonomy, Regulation, and Connectivity are Megatrends impacting the future of mobility, and plastic materials play an important part in each of these large scale changes that will ultimately remake 'what' a light passenger vehicle is and does, and 'how' humans are transported in the future. This paper will touch on each of these trends and the potential impact on the Auto sector.

Low Temperature Solution Depolymerization Of Pla
John Campanelli, May 2018
A novel depolymerization method using low-temperature, low-pressure alcoholysis of PLA in a ternary solution is outlined in this work. Depolymerization kinetics are studied for the PLA/methanol/chloroform system at 57°C. Large changes in molecular weight can be achieved at relatively mild conditions. A tin catalyst is found to increase the reaction rate significantly. The method is well-suited to industrial recycling processes and is consistent with the concept of a circular economy.
Mechanical Properties And Effects Of Microfibrillation Of 100 % Biomass Sisal-Pla Composite
Hiroyuki Nishimura, May 2018
The mechanical properties of sisal-PLA composites were measured with a parameter of length of sisal fiber, degree of microfibrillation, and mixing method of sisal fiber. The mechanical properties of sisal-PLA composites were also compared with those of wood flour, cellulose based on hardwood, and cellulose nanofiber composites. As a result, the higher tensile strength of the sisal-PLA composite was obtained by kneading PLA and microfibrillated sisal fiber wetted with organic solvent.
Synthesis Of High Hardness Polyester Resin For Powder Coatings
JUNSEOP IM, May 2018
Since powder coatings do not use VOCs, much research has been studied as eco-friendly paints. Among these powder coatings, hybrid type is widely used in home appliances and furniture. Therefore, it is very important to meet both aesthetic characteristics and mechanical properties such as gloss and hardness. However, it is difficult to maintain high gloss with high hardness because of the inorganic filler of powder coatings.
On The Use Of High-Throughput Electrospinning To Produce Optimized Packaging Films From Polyhydroxyalkanoates
Sergio Torres-Giner, May 2018
This study describes the preparation and characterization of electrospun films made of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) produced by mixed bacterial cultures derived from a cheese whey (CW) industrial by-product. A mild thermal post-processing step carried out on the electrospun fibers mat, at a temperature below the biopolymer’s melting point, yielded a film with high transparency, enhanced crystallinity, and potentially sufficient mechanical and water barrier properties for sustainable packaging applications.
Nanocellulose As A Sizing Agent For Glass Fiber Towards An Enhanced Glass Fiber – Epoxy Interphase
Joyanta Goswami, May 2018
Glass fiber/nanocellulose/epoxy interfacial adhesion was explored to determine the optimum coating process and nanocellulose surface chemistry for glass fiber reinforced epoxy composites. The interfacial adhesion was assessed by photoelastic scattering under a microscope and interfacial shear stress (IFSS) determination by single fiber fragmentation test (SFFT). The effect of nanocellulose as glass fiber coating on the interphase was determined and prospects of nanocellulose sizing of glass fibers (GF) were discussed.
