China High Stiffness Manufacturer, Supplier, Factory

Our company has recently launched two rotational molding PP materials with certain transparency, each with different focuses. Let's take a look at the specific differences below. This product has good transparency, with a transparency of up to 55% -60%. It is transparent throughout and suitable for making products that require a certain level of transparency;

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?

On August 20th, Professor Wang and Professor Li, who are responsible for polyolefin research at Zhejiang University, visited our company for exchange. General Manager Wen Yuan introduced them to the development history of the rotational molding industry, the main sources of rotational molding base materials, the specific application scenarios of rotational molding products, and our company's development situation.
