Polycarbonate, with its established history of innovative applications in the E/E and automotive arenas, can prove to be a key material for the new ‘e-mobility’ market, according to Pittsburgh-based Covestro. At the upcoming VDI “Plastics in Automotive Engineering” Congress (Manheim, Germany; March 14-15), Covestro will highlight new concepts based on PC that are being driven by new technologies.

Take a look as how pricing was trending from polyolefins, PS, and PVC as we enter the third week of this shortened month, with insights from Houston-based PetroChemWire (PCW), and Michael Greenberg, CEO of the Plastics Exchange in Chicago.

PE: Both PCW’s senior editor David Barry and The Plastic Exchange’s Greenberg characterized spot market activity as having pulled back, owing to limited availability. LDPE and HMWPE film grades were the tightest due to recent supply issues, noted Barry. “There was a bit of a run on spot HDPE blow molding grades, with prices jumping up 2¢/lb as suppliers snugged up,” reported Greenberg. He added that high-clarity LDPE added a half-cent, while LLDPE butene lost the same. This reset the fairly typical full 5¢/lb premium between the two.

It’s easy to understand why equipment monitoring is so often overlooked. Monitoring systems can be impossible to install, difficult to customize, with data that’s hard to understand and act upon. For companies who want to avoid all of the complexity, some opt to hire a technician to handle it for you, and some skip equipment monitoring all together.

A key trend in automotive is the use of multi-material structures and, in turn, the ability to structurally join dissimilar materials and keep them together during the vehicle’s useful life, yet the need to separate them for repair, rejoin them and then separate them again at end-of-life for recycling has become increasingly important. This is particularly key for primary vehicle structures, which are far more safety critical than interior or exterior panels and, as such, vital to prevent unwanted separation during vehicle operation. They are also costlier to replace, which makes them highly desirable targets for repair rather than the junkyard if damaged.

We’ve reported on stretch film, t-shirt bags, institutional can liners , and shrink film in previous installments of this blog series, which provide snap shots of the results of 2017 research conducted by market-research firm Mastio & Co., St. Joseph, Mo. on the PE film industry. Here, we recap Mastio’s research on consumer can liners.

The consumer trash bag market can be divided into the categories of national brand, private label, and generic market segments, the Mastio study notes. All three types of bags can be purchased by consumers in a variety of places including grocery stores, mass merchandise stores, and discount stores. National brand and private label bags are usually sold at a higher price than generic bags. Typically, there is very little, if any, advertising to promote the generic bags, further helping to lower the costs to consumers.
