After 1 to 2 days of on-site installation and commissioning by the COWIN after-sales team, the production line has been formally launched. This marks the 7th maleic anhydride grafting line purchased by the client.
Tailored exclusively for the maleic anhydride grafting process, the line is dedicated to manufacturing various compatibilizers and toughening agents. It adopts the CHT65D high-torque twin-screw extruder with an L/D ratio of 52. Screws and barrels are made via HIP technology featuring outstanding wear and corrosion resistance, equipped with a double-plunger non-stop screen changer. Supporting auxiliary facilities adopt a self-developed underwater pelletizing system. The advanced devolatilization and vacuum venting system lays a solid foundation for low-VOC compatibilizer production.
The client has maintained long-term in-depth cooperation with COWIN and sourced all production equipment from our company. COWIN provides customized twin-screw granulation solutions to suit its technical demands for mutual development. Supported by scientific research resources from East China University of Science and Technology and a postdoctoral research station, the client has grown into a comprehensive high-tech enterprise integrating formula design, testing, R&D, and sales services.
Boasting core advantages in high grafting rate, eco-friendly low odor, low residual content, and black spot control, its core products, including PP-g-MAH, PP-g-GMA, POE-g-MAH, and POE-g-GMA, are widely acclaimed in engineering plastics, photovoltaic materials, cable materials, polymer alloys, and nano-material industries.
Committed to win-win cooperation, value creation, and joint progress with clients, remains COWIN’s consistent development philosophy.
