Meeting the diverse needs of our customers has always been our unremitting goal. For the insulation box industry, we have integrated our various resources and now have the ability to provide a series of customized supporting products for insulation box production enterprises:

Melt flow rate (referred to as melt index) is an important performance indicator of rotational molding materials, which has a significant impact on the processing and forming of rotational molding products. It also has important application value in rotational molding modification and other fields. However, in the modification process, which mixing rule should be followed for the melt index of the mixture?

From November 1st to 3rd, 2024, our company participated in the 2024 China International Plastics Exhibition. At the exhibition, our company showcased the latest research and development of various trendy products using rotational molding materials, fully demonstrating our focus on the development of the rotational molding industry and our unwavering commitment to serving customers in the industry.
