Responding to the growing global awareness of modern plastics' environmental impact and the depletion of fossil-based raw materials, Palsgaard A/S, a Danish company that pioneered plant-based polymer additives, has developed a full range of plant-based alternative ingredients for sustainable materials production. As plastics are utilized in an ever-growing range of sophisticated industrial applications, polymer manufacturers are continuously developing new polymer materials. These new polymer formulations have to be carefully designed to meet individual applications' demanding requirements in key industrial sectors, such as automotive and aerospace industries, healthcare, food production, and consumer goods manufacturing. Tailor-Made Polymer Materials ...

Jaguar Land Rover on Tuesday announced it had launched a four-year research project aimed at increasing electric vehicle usage and producing lighter vehicles through composites. “The research will allow Jaguar Land Rover to develop lightweight vehicle and powertrain structures by replacing aluminium and steel with composites capable of handling the increased torque generated by high-performance batteries, while improving efficiency and reducing CO2 impact,” the OEM wrote in a news release. Jaguar Land Rover said it sought to cut weight by more than 76.16 pounds, increase stiffness by 30 percent, and upgrade vehicle crashworthiness with “through the strategic use of tailored composites, such as carbon fibre.” Graphics accompanying the news release ...

PolymPart: Toray Industries has created a polymer that retains the outstanding thermal resistance, rigidity, and strength of polyamide 6 (PA6) while delivering a bending fatigue limit that is 15-fold that of conventional polymers. Prospective applications for such exceptional durability include automobiles, appliances, and sporting goods. Toray looks to initiate full-fledged sample work in fiscal year 2021 while cultivating applications in diverse industrial materials fields. PA6 is an engineering plastic whose diverse uses include automobile engine compartments and appliance housings. PA6 resin incorporates a flexible elastomer  to resist fatigue and optimize the lifespan. The tradeoff, however, is that this lowers PA6’s thermal resistance, rigidity, ...

A new technique promises deeper insights into polymer degradation in high-shear conditions
06 ژانویه 2021

Ultra-long polymers are used widely in high-performance applications including energy-efficient lubricants, working fluids for energy production and performance plastics. Yet they also are often degraded by extreme flows and mechanical processes that break chemical bonds along the “spine” of the polymer chain. Motor oil in your car is a good example, explains Matthew Helgeson, an […]

A wearable sensor printed on natural polymer for monitoring body fluids present in sweat
18 آگوست 2020

A wearable sensor printed on microbial nanocellulose, a natural polymer, has been created in Brazil by researchers at the University of São Paulo (USP) in São Carlos in collaboration with colleagues at São Paulo State University (UNESP) in Araraquara, the University of Araraquara (UNIARA), the University of Campinas (UNICAMP), and the Brazilian National Nanotechnology Laboratory […]

RADIATION SHIELD, POLYMER MAY REPLACE LEAD
13 مه 2020

PolymPart: The bismuth trioxide compound is lightweight, effective at shielding against ionizing radiation such as gamma rays, and can be manufactured quickly. Those qualities make it a promising material for use in applications such as space exploration, medical imaging, and radiation therapy. “Traditional radiation shielding materials, like lead, are often expensive, heavy, and toxic to […]

German institute designs polymer camshaft module
09 مه 2020

In a bid to reduce engine weight and lower manufacturing and assembly costs, the Fraunhofer Institute for Chemical Technology ICT has designed a camshaft module made from fiber-reinforced thermoset polymers. Currently available as a technology demonstrator, the lightweight camshaft module between ICT and the MAHLE Group, along with associated partners Daimler, SBHPP/Vyncolit and Georges Pernoud. […]

New smart materials from ionic liquid–polymer composites
16 آوریل 2020

Ionic liquids have emerged as a novel class of chemical compound for the development of advanced materials with outstanding potential applications. Although ionic liquids were discovered as early as 1914, it was only in the last two decades that they have received their due attention, as it was recognized that the physicochemical properties could be […]

Asia polymers face more weakness as virus cuts demand
24 مارس 2020

PolymPart: Polymer prices in Asia are coming under further pressure because of a lack of resin demand as the region grapples with the coronavirus pandemic. Polypropylene (PP) and polyethylene (PE) prices have steadily declined since the coronavirus outbreak worsened in January, and the search for a bottom continues. Spot prices of linear low-density PE (LLDPE) […]

Increasing the service life of polymer electrolyte fuel cells with a nanodispersed ionomer
18 فوریه 2020

PolymPart: Protons (subatomic particles) can be transferred from the anode to the cathode through the ionomer membrane in polymer electrolyte fuel cells (PEFC). Scientists can extend proton pathways by impregnating the ionomer (type of polymer) into the electrodes to achieve improved proton transfer efficiency. Since the impregnated ionomer can mechanically bind catalysts within the electrode, […]
