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.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
