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.

At present, the intelligent power grid project is flourishing, and the construction of distributed power stations is also vigorously promoted, which puts forward higher requirements for the electrical safety performance of high-voltage cable joints. The original conventional coating materials can no longer meet the higher performance requirements of flame retardancy and voltage breakdown resistance.
