Almost-infinite number of polymer materials ‘excites’ 3D printing exec
The founders of AON3D started the company in 2015 with the goal of developing a competitively priced, filament-style 3D printer that would let customers produce parts from nonproprietary, high-performance thermoplastics. The Montreal startup—founded by a group of McGill University materials engineers—achieved its goal and since then has upgraded the printer’s design several times. The latest iteration is the recently released AON-M2, which can build parts from nylon, polycarbonate, UltemTM, PEKK, PEEK, TPU (thermoplastic polyurethane), and many other materials. It features a 120-degrees-C bed; an expansive 18- by 18- by 25-in. build envelope; dual, independent extruders; and it can be operated remotely without installing software. Company Cofounder and CEO Kevin Han said the M2 fills a niche between desktop-style “prosumer” systems and industrial systems. The Additive Report met with Han at Formnext 2019 in Frankfurt, Germany, where he spoke about AON3D’s beginnings, the decision to focus on high-performance polymers, and steps that will spur growth of the additive manufacturing (AM) industry.
New generation of stabilizers for high-quality polyolefin recyclates
German companies Brüggemann and Fraunhofer LBF have joined forces to successfully tackle one of the seemingly insurmountable problems of plastics recycling. During their lifetime, plastic articles are subjected to thermal oxidation and photo-oxidation, which can create enough damage to prevent them from being recycled into high-quality products. In order to overcome this problem, researchers at the Fraunhofer Institute for Structural Durability and System Reliability LBF, Darmstadt, have developed new stabilizer systems to improve the properties of polyolefin recyclates, especially those made of polypropylene and polyethylene. These pioneering stabilizers are capable of reducing the effects of previous damage to such an extent that recycled materials become suitable for processing into sophisticated molded products. In its ongoing development, Fraunhofer LBF is collaborating closely with L. Brüggemann GmbH & Co. KG, a leading manufacturer of tailor-made high-performance additives for engineering plastics, who will also be responsible for production and worldwide distribution.
The polyacrylonitrile precursor must be stabilized before the high temperature heat treatment that actually converts it to carbon fiber. The precursor is heated in air to between 200ºC and 300ºC for about 1 hour. Because of the temperature range, and especially because the process is exothermic, the heating is done with forced convection ovens. Convection allows both efficient heating of material as it enters the oven and removal of exothermic heat where the chemical reactions are most active.

PPSU features improved flowability for complex-shaped components in catering, aircraft
BASF is expanding its Ultrason P product range with a particularly low viscosity grade. The new polyphenylsulfone (PPSU) Ultrason P 2010 is characterized by improved flow behavior in injection molding while maintaining the excellent mechanical properties of Ultrason P.
Circular Economy' Dominates Discussion of Resins, Additives at K 2019
Our September show preview discussed the increasing number of upstream and downstream industry collaborations underway in chemical and mechanical recycling, biobased feedstocks, and new resins offered with recycled and biobased content. While a good portion of these efforts involve polyolefins, headway also is being made with other resins such as polystyrene, styrenic blends, and nylons, as previously reported. And, at the show, we saw the launch of the first renewablefeedstock polycarbonate (PC).
A Korean company plans to expand its production of a key component for producing semiconductors and displays, Korean trade officials announced Wednesday, continuing the country’s campaign to lower its dependency on Japanese imports of the materials amid recent trade tensions.The Korean Ministry of Trade, Industry and Energy announced on Wednesday that Dongjin Semichem, a local company specializing in materials for semiconductors and displays, submitted plans to expand its photoresists production plant in the first quarter of this year.Japan started restricting exports of three key chemicals photoresists, hydrogen fluoride and fluorine polyimide essential to making semiconductors and displays last summer. Semiconductors and displays are two of Korea’s leading exports.
