Resin price report: Demand improves, supply tightens in spot PP and PE markets
Plastics Today
The week of Oct. 17 was the most active of the month so far in the spot resin markets, reports the PlasticsExchange in its Market Update. Average prices for both polyethylene and polypropylene held flat amid better demand and tightening supplies. Resin producers have made a concerted effort the last couple of months to rebalance supply and demand and regain pricing power by aggressively reducing reactor run rates alongside massive discounting to increase exports. The strategy appears to be working.

Scientists astonished by strange material that can be made like plastic but conducts like metal
SciTechDaily
‘Like conductive Play-Doh’: breakthrough could point way to a new class of materials for electronic devices.
University of Chicago scientists have discovered a way to create a material that can be made like a plastic, but conducts electricity more like a metal. The research shows how to make a kind of material in which the molecular fragments are jumbled and disordered, but can still conduct electricity extremely well.

Plastic deformation in silicon nitride ceramics via bond switching at coherent interfaces
Science
Ceramics are not known for deforming in a plastic manner, instead tending to fracture as a response to loading. J. Zhang et al. found a method to avoid fracture and dramatically improve the ductility of silicon nitride (see the Perspective by Frankberg). The authors produced dual-phase silicon nitride samples that turned out to have coherent interfaces between the phases.

UBC scientist discovers way to make strong plastic alternative from grass crops
Vancouver Sun
University of B.C. researchers have stepped up to find sustainable solutions to replace plastics, which don’t break down in the environment and can harm wildlife.
Johnson, who works in the department of wood science at UBC’s faculty of forestry, has created a bioplastic from agricultural crops that belong to the grass family such as wheat, corn and oats. She only uses the stalk from these grass crops so she’s not taking away a food source, which is important as food scarcity linked to climate change becomes more of a threat.

Researchers 3D print degradable polymers using salt
Phys.org
Dr. Emily Pentzer, associate professor in the Department of Materials Science and Engineering and the Department of Chemistry at Texas A&M University, is making 3D-printed polymers more environmentally friendly through a process that allows the polymers to naturally degrade over time. Pentzer's research is a collaborative effort that includes researchers from the Texas A&M College of Engineering, the Texas A&M Engineering Experiment Station, the Texas A&M Department of Chemistry and the University of Kashmir.

Promoted by Polyfil
 Polyfil, a Kafrit Group company, together with Kafrit IL and N3Cure (an Israeli based Start Up) provides solutions for UV curing systems and CROSSITOL® masterbatches. Crosslinking enables the production of recyclable packaging with a single-polymer structure (Mono-material), saving costs and reducing the consumption of fossil-based polymers. As a result, it will have a smaller effect on the environment than most plastic solutions.
CROSSITOL® masterbatches can be used in a wide range of applications including cast and blown film extrusion. Its technology is coupled with N3Cure’s curing system to target specific layers for crosslinking, downgauging, and production costs.
