We usually believe that rotational molding products can meet their design requirements by increasing the wall thickness of the product when under pressure. But after our research, we found that this is not the case. Come and see what's going on!

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.
