As an OKC Thunder fan, I don’t enjoy anything about the Golden State Warriors. But as much as it pains me to post a story with a photo of the Golden State uniforms, it does relate to plastics recycling so here it is:

Nike is now the official partner of the NBA, replacing Adidas, and the company recently revealed the new jerseys for the 2071-18 season. The uniform is comprised of a combination of Alpha Yarns and recycled polyester, with each athlete’s uniform representing approximately 20 recycled PET bottles. Nike claims that the yarn blend removes moisture more quickly than previous NBA uniforms, wicking sweat 30% faster than current NBA uniforms.

MTD Micro Mold micro injection molded parts

Exhibit A: MTD Micro Molding, Charlton, Mass., a long-time leader in medical micromolding, just announced that it made the “Inc. 5000” list of America’s fastest-growing companies—for the second time. MTD Micro Molding was ranked #4735 due to its three-year growth of 48%. The first time it made the list, in 2011, it was ranked #1274 overall and #36 in manufacturing, owing to its three-year growth of 228%.

“I’m so proud of my team!” said Dennis Tuly, president of MTD. “Making the Inc. 5000 list for the second time validates our efforts to remain in the forefront of micro manufacturing.”

resin prices August 2017

Moving into the third week of August, PetroChemWire (PCW) added polystyrene (PS) to its weekly reports just as August contracts appeared to have rolled over and one supplier issued a 2¢/lb hike, effective Sept. 1. This driven by higher spot benzene and styrene monomer prices and relatively balanced supply, according to Senior Editor Dave Barry.

Meanwhile, the PCW weekly reports on PP and PVC indicate any price relief is unlikely in the near term, while PE prices may possibly roll over and not move up despite suppliers’ intentions. Here are key takeways from these weeklies and from the Aug. 18 market update of The Plastics Exchange.

sheet extrusion

Check out all the details for Plastics Technology’s upcoming Extrusion 2017 Conference. It’s going to be held Oct. 18-20 in Charlotte, N.C. at the Sheraton Charlotte Hotel in the downtown section of the city.

This two-and-a-half-day event—Plastics Technology’s third such conference—is packed with presentations from more than 80 technical experts covering a wide range of subject areas. The morning sessions on all three days day will consist of presentations on general extrusion topics. During each afternoon of the first two days, there will be three concurrent breakout sessions that hone in on your particular process: film, sheet; pipe/profile/tubing; and compounding.

Over the last several years, achieving thermal conductivity in plastics in applications such as high-power density electronic devices, automotive cooling systems, and batteries, where heat accumulation can have deleterious effects, has been achieved by blending the plastics with highly thermally conductive fillers such as metal or ceramic particles, carbon nanotubes (CNTs), or graphene flakes.

The key challenge, however, has been the large volume fraction of such fillers required to achieve appreciable enhancement in thermal conductivity, which often leads to undesired optical or electrical properties, increased weight, high cost, and at times loss of the easy processability typically associated with plastics.
