NPE2012—the first year the triennial trade show was held in Orlando—was promoted as “The Return of the Machines” in the months leading up to the show. And that turned out to be prophetic, as machine builders brought lots more equipment to the exhibit floor than they did in the scaled-back NPE2009. The trend continued at NPE2015; and at last month’s NPE2018, there were a reported 2 million more pounds of equipment on the floor than at any previous NPE. Wow. And quite a bit of that machinery and equipment was humming and buzzing all week long. Great news for our industry indeed.

But as I made my way from the West Building, where most of the machinery companies were exhibiting, toward the South Building of the giant Orange County Convention Center, I was struck by something I consider equally impressive: large exhibits belonging to materials companies, many of whom over the years had scaled back if not altogether dropped their presence at NPE (but, notably, not at Chinaplas nor the K Show in Dusseldorf).

I mentioned my observation to Matt Naitove, executive editor of Plastics Technology magazine. You see, Matt knows a thing or two about NPEs: 2018 marked his 16th show (I’ve been to 10). He quipped, “Well, I guess the pellets have returned too.”

While not as grizzled as Matt, I’ve been around in plastics journalism since 1988. When I  started, the materials companies were the primary newsmakers in the industry. Quite a few would hold annual press conferences touting new materials and applications.

Others would regularly invite the plastics media to attend their facilities for open houses and other such news-making events. For sure, there were significant developments in machinery as well, but the big breakthroughs were in materials.

Then things started to slow down.

Suppliers of engineering resins seemed less interested in communicating news of their developments to processors—our core audience—and keener on talking to designers at OEMs. The OEM designers are important for certain, but isn’t it best to keep both links in the plastics manufacturing chain well lubricated? And suppliers of polyolefins? Well, I remember a conversation I had on this matter in the mid-90s with a mid-level manager at a major polyolefin supplier, and that person opined, “Our material is the same as that company’s, and that company’s, and that other company’s too. What’s there to talk about? What’s there to market? We just want our people selling it.” Obviously, that was this exec’s way of expressing the commoditization of PE and PP.

Was that person right or wrong? Perhaps it may have been a correct assessment at the time, but the winds of change have shifted. Perhaps plant expansions driven by inexpensive feedstocks like shale gas are one reason. Maybe—as some major suppliers have predicted—processors from abroad are looking to establish a manufacturing footprint in the North American market. In any event, I see more news coming from materials companies—and not just on exotic engineering thermoplastics but on bread-and-butter polyolefins as well—than I remember seeing in a long time. And not just about resin, but about additives that when dosed teach the base material new tricks. So-called commodity polymers are indeed being engineered to accommodate a marketplace that is demanding better performance and more speed.

I think it’s in the best interest of our industry that materials suppliers communicate up and down the manufacturing chain. Processors may not always buy the material—lots of times the bigger OEMs do the negotiating to take advantage of their economies of scale—but for certain it’s always being run through their machines.

I’m hoping what I saw at NPE2018 is a sign of things to come.
