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?

Our company's "yellow card" (UL certified card) family has added a new member. As mentioned in the previous video, our material LLD610P has passed the HB level yellow card certification. This time, our material LLD302V0P has passed the V0 level yellow card certification, which is a heavyweight UL yellow card certification.
