Green polypropylene foam material is characterized by light quality, sound insulation, heat insulation, impact resistance, non-toxic, and easy to fall in light solution, it is expected to replace toxic EPS as green packing materials,
Due to its low melt strength, and it is difficult to foam, only a few companies in Japan and Germany can produce green polypropylene foam material up to now.
Dr. ZHENG Wenge from the Polymers and Composites Division, NIMTE is recognized for pioneering contributions in green polypropylene foam material, he explored a new research approach by using general-purpose polypropylene as a raw material, inorganic carbon dioxide as blowing agent, so that supercritical carbon dioxide can be uniformly mixed with the polypropylene melt to achieve a continuous foam, the density of polypropylene is less than 0.04g/cm3.
Since the process is stable, its manufacturing cost is very low, and it can start mass production, the achievement has attracted many enterprises. Yuanrong New Materials Co., Ltd in Anhui province, which is one of the most complete varieties of modified plastics industries in China, preemptively signed a cooperation agreement with NIMTE.The total investment is up to 75 million Yuan. NIMTE will hold 23% shares by technology investment.
