The economy may be weak, but not the entrepreneurial spirit. A major new nylon producer emerged at the National Plastics Exposition this week in Chicago. The new producer is Invista, a company that was formed more than five years ago from assets spun off from DuPont. Based in Wichita, KS, Invista is one of the world’s largest producers of polymers and fibers, primarily for apparel and carpeting and other applications. Brands include Stainmaster carpet and Lycra apparel, both once iconic names in the DuPont portfolio. The assets were purchased by Koch Industries as DuPont repositioned into other markets-a strategy still unwinding for many chemicals companies.
Invista has been selling polyester resins, including PBT-type polyester for engineering applications. Koch had signed a five year non-compete for nylon resins. That agreement has now expired, and Invista enters the market with a lot of nylon-producing firepower. “We’re taking a more focused approach by creating a simplified portfolio of products, each with the ability to perform in numerous applications,” said Kurt Burmeister, executive vice president on Invista’s engineering polymers business. “The benefits are economics of scale and customer flexibility, due to less complex operational systems and reduce inventory requirements.” Burmeister told Design News that Invista will sell a variety of compounded nylon products using an array of toll compounders operating as contract manufacturers. Emphasis will be on nylon 6,6.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
