18 Extrusion International 1/2020 INDUSTRY NEWS High-Performance Thermoplastic Film Solvay has signed an agreement with Safran to supply Halar ® ECTFE high performance film for its LEAP1 engine acoustic panels. Filmmade fromHalar ® ECTFE with additional plasma treatment of- Solvay Specialty Polymers www.solvayspecialtypolymers.com fers excellent adhesion to composite substrates providing superior aesthetic surface aspects to perfectly blend with its surroundings. Solvay’s high-performance Halar ® ECTFE, a partially fluorinated semi-crystalline polymer, is used as a protective layer on the engine acoustic ring panel against the aggression of the harsh environ- ment typical of the entrance of an aircraft engine. It is strong and tough and its resistance to erosion, abrasion, and aircraft chemicals and fluids make it ideal for this application. Solvay’s Halar ® ECTFE film retains its properties over a broad range of temperatures, displaying particularly outstanding impact resis- tance at low temperature. It has demonstrated excellent erosion properties, extreme UV radiation resistance and can be considered as an excellent barrier to water vapor, oxygen and other small gas molecules. It is also lightweight and durable and meets stringent aerospace industry requirements regarding fire and burn-through resistance due to its inherent flame retardancy. 1 The LEAP engine is a product of CFM International, a 50/50 joint company between GE and Safran Aircraft Engines. ® Halar is a registered trademark of Solvay Twin-Screw Extruder Manufacturer equips a new Pelletizing Line with an Underwater Pelletizer Extruder manufacturer Useon (Nanjing) Extrusion Machinery Co., Ltd. has installed a 70,000 ton per year polypropylene pellet- izing line that incorporates a BKG ® underwater pelletizer from Nordson Corporation. The new line, which is up and running at the facility of an Indo- nesian customer, is powered by Useon’s SAT-X 175 co-rotating twinscrew extruder. The unit has a 2,000 kW motor and Useon’s patented high-torque gearbox. The throughput of the line is 8 to 10 tons/hour. “The start-up is the culmination of a mega-integrated polyolefin pelletizing project in which Useon was responsible for design, manufacturing, installation, and commissioning,” said Allen Zhang, sales manager for Useon. “The size of the project and our comprehensive role in it marks a milestone for made-in-China twin-screw technology in a market until now dominated byWest- ern suppliers.” The pelletizing component from Nordson includes the BKG AH D 300 underwater pelletizer, with throughput capability up to 35 tons per hour, and the Optigon™ 5 automatically self-cleaning water and dryer system, with throughput up to 15 tons per hour. BKG pelletizers are widely used in China and elsewhere, noted Aaron Kong, Nordson sales director for China. “To support this market, last year we started up a new pelletizing laboratory line at our facility in Shanghai, including a 300 kg per hour twin-screw extruder. It isused by our direct customers as well as OEM compa- nies like Useon, whose customers can run trials in our lab to dem- onstrate our BKG equipment.” Nordson Corporation www.nordson.com www.nordsonpolymerprocessing.com Useon Extrusion www.useon.com Since established in 2006 in Nanjing, China, Useon Extrusion has successfully delivered more than 2,600 twin- and single-screw extrusion lines worldwide for polymer processing applications in- cluding compounding, direct extrusion, foam extrusion, and recy- cling. They are headquartered in Nanjing, Jiangsu, China.
