From the Sector

Die Bottle-Systeme des österreichischen Recyclingmaschinenbauers EREMA sind seit 25 Jahren am Markt, knapp 50 Prozent der in den letzten drei Jahren ausgelieferten Bottle-Anlagen wurden in Asien installiert. Die Herstellung von lebensmitteltauglichem rPET rückt dort immer mehr in den Fokus – auch in der Textilbranche. EREMA unterschreitet nicht nur die strengen Grenzwerte der weltweit anerkannten europäischen und nordamerikanischen Behörden für Lebensmittelsicherheit, sondern auch jene von globalen Markenartiklern. Bei der Chinaplas von 23. bis 26. April 2024 in Shanghai präsentiert das Unternehmen sein Portfolio.

Lebensmittelechtes rPET im Aufwind – auch in der Textilindustrie
Zusätzlich zum Lebensmittelbereich spielt lebensmittelkonformes rPET in der Textilindustrie eine zunehmend größere Rolle. Rund zwei Drittel der Gesamtmenge an PET fließen in die Produktion von synthetischen Fasern. EREMA reagierte darauf mit der Gründung einer eigenen Business Applikation für Fasern und Textilien.
Marken setzen immer öfter auf recyceltes PET als Ausgangsmaterial, das den Anforderungen für Food Grade entspricht, um ihren Kunden nachhaltige, gesundheitlich unbedenkliche Textilien anbieten zu können. Ein Trend, der sich bei EREMA im steigenden Absatz von Bottle-to-Fibre Anwendungen widerspiegelt. Asien ist in diesem Segment ein wichtiger Markt.

Schonende Materialaufbereitung für Faser-zu-Faser
Speziell für das Faser-zu-Faser-Recycling wurde die INTAREMA® FibrePro:IV Maschine entwickelt. Durch die Kombination der INTAREMA® Technologie mit dem neuen IV-Uptimiser gelingt es, durch Spinnöle stark kontaminierte geschredderte PET-Fasermaterialen so aufzubereiten, dass aus dem Regranulat wieder feinste Fasern produziert werden können. Die Anlage zeichnet sich durch eine gezielt aktive Oberflächenerneuerung der Schmelze unter Vakuumatmosphäre aus, wodurch Spinnöle und andere Hilfsstoffe effizienter entfernt werden als bei herkömmlichen PET-Recyclingverfahren. Nach der Extrusion wird im IV-Uptimiser die intrinsische Viskosität durch Polykondensation der PET-Schmelze wieder auf jenes Niveau erhöht, wie es für die jeweilige Faserproduktion nötig ist.

Um die Entwicklungen im PET-Faserrecycling voranzutreiben hat die EREMA Gruppe ein eigenes Faser-Technikum am Stammsitz in Ansfelden, Österreich geschaffen. Hier betreibt ein interdisziplinäres Team eine umfangreich ausgestattete und variable Recyclinganlage im Industriemaßstab. Sie ist mit der notwendigen Peripherietechnologie ausgerüstet und steht auch Kunden für Testläufe zur Verfügung.

•    New, sustainable, ready-to-use solutions for plastic auto parts to support China’s electric vehicle boom
•    Stronger, softer nylon polyamide fibers plus fast processing for clothes, carpets & industrial applications
•    AddWorks blends lower total cost of ownership & reduce production complexity while enhancing performance

Muttenz, May 3, 2018 – Clariant, a world leader in specialty chemicals, introduced new additive solutions for plastics materials at Chinaplas 2018.

“Our innovations focus on higher performance at better convenience for a sustainable future,” says Stephan Lynen, Head of Clariant BU Additives. “At Chinaplas 2018 we demonstrated our technical and market capabilities around the theme of e-mobility. The immense changes in mobility call for lighter, safer and smarter vehicles. We offer new additive solutions, such as AddWorks, and technical capabilities to respond to this demand. We are accompanying this with a series of investments such as new production facilities in China.”

Clariant’s new AddWorks solutions – AddWorksATR 146, AddWorks LXR 568 and AddWorks TFB 117 – are specifically aimed at improving performance and efficiency of plastics materials for compounders, polymer and fiber producers in China’s major plastics manufacturing segments. All three solutions are part of the globally available portfolio.

The full AddWorks portfolio consists of differentiated market-specific synergistic additive blends that streamline production processes and create value for customers while enhancing performance. Each solution is customized to specific market needs, underlined by broader considerations such as emission reduction, and less energy and resource usage.

Sustainability and performance for the world’s largest auto market
To support the significant investment in electric vehicles in China, Clariant launched two additive innovations that improve the lifetime of lightweight automotive parts and under-the-hood applications and reduce VOC emissions in an easy to use single solution.

AddWorks ATR 146 is a new low dosage, sulfur-free heat and light stabilizer for filled polypropylene (TPO) compounds used in interior applications. Its exceptional heat and light stability and long term color retention offers the automotive industry unmatched performance. It shows no surface cracking after 700 hours at 150°C, which enables dashboards, instrument panels, door panels and pillars to maintain their aesthetics longer than with traditional stabilizers. It also contributes to reducing blooming and VOC emissions, supporting the common effort to make automotive interiors healthier and odorless.

AddWorks LXR 568 is a high performance processing stabilizer that helps to prevent plastic resins, especially polyolefins, from degradation at high processing temperatures. For the automotive industry, this reduces the tendency of injection molded polypropylene interior car parts to turn brittle during heat exposure, enabling them to maintain a defect-free surface. It also has low migration and low fogging that support healthier in-cab environments.

AddWorks LXR 568 combines outstanding color and melt flow protection with good resistance to hydrolysis and high thermal stability. This makes it ideal for interior and under-the-hood powertrains and wider application areas such as packaging films. It is available in free-flowing pills and micro-pills which are easy and convenient to use.

Softer, stronger polyamide fibers for clothes, carpets and industrial applications
Within the next three years, China is expected to account for 40% of the world’s nylon production and more than 30% of the nylon resin consumed globally[1]. The new AddWorks TFB 117 offers a number of benefits to help stabilize and smoothen fiber production processes, protect color, and improve heat stability and mechanical properties of fibers. AddWorks TFB 117 ensures smooth spinnability with less filaments breakage, even at low processing temperatures and at high speed spinning up to 5,500 m/min.

Martin P. J. John, Head of BL Performance Additives at Clariant, comments: “AddWorks solutions are an ideal fit with China’s priority of achieving more sustainable production. They save time and reduce complexity along the production process, with easy to use formats that reduce health risk and chemical waste. Our new state-of-the-art production facility in Zhenjiang, China, which opens later this year, is dedicated to the manufacturing of AddWorks to deliver innovative solutions tailored to the needs of the market. Made for China in China.

In addition to AddWorks, Clariant presented Exolit® OP 1400, a highly stable non-halogenated flame retardant enhancing safety during the charging process. It also provides outstanding thermal stability for under the hood applications. Exolit OP 1400 has been awarded the Clariant EcoTain® label for outstanding sustainability and performance.  

Clariant also introduced two ranges of performance waxes that smoothen the production of automotive plastics for under the hood applications, Licowax® and Licocare® RBW. The recently launched Licocare RBW is a series of multi-purpose additives based on crude rice bran wax. They offer better shaping flexibility, better mechanical properties and enhanced surface finish, which results in a reduced rejection rate and a more effective dosage.
