PPC materials research in China has achieved 7 world firsts
China branch hopes to help you! Recently, good news came from Changchun Institute of applied chemical energy saving design of the college. After 8 years of research and cooperation with enterprises, the Institute broke through a series of technical keys in the research of carbon dioxide degradable plastics (PPC), and set seven world firsts in this research field
the seven research achievements are: to build the world's first and largest 3000 ton/year PPC production line in Inner Mongolia; For the first time in the world, the glass transition temperature of carbon dioxide polymer is increased to -10 ℃ ~120 ℃, and the service temperature is increased to 70 ℃, which greatly expands the application range of PPC; Take the lead in developing carbon dioxide copolymers with number average molecular weight of more than 150000, weight average molecular weight of more than 1million and carbon dioxide content of more than 42% (mass ratio); For the first time, a high barrier film material with complete biodegradability was produced, which can be used in food packaging materials on a large scale; It is the first in the world to break through the processing bottleneck of continuous blowing of carbon dioxide copolymers into films and develop a large area of continuous film preparation technology with China's independent intellectual property rights. The above experimental standards refer to ISO, ASTM, DIN, GB, BS, JIS, etc; PPC medical dressing was successfully developed, the enterprise standard of the dressing was established, and the production license of the world's first carbon dioxide copolymer medical disposable degradable material was obtained
carbon dioxide copolymer (PPC) is a green polymer material synthesized by polymerization with carbon dioxide as the main raw material. This new biomaterial can not only turn carbon dioxide into treasure, but also be completely biodegradable. It is an important green biomaterial for saving oil resources and sustainable development
