Polyolefin Powder Granulation

Overview:

The polyolefins comes from a powder form which is prone to oxidative degradation. This complicates its storage, transportation, and downstream applications. Therefore, granulation is necessary to stabilize performance.

The polyolefins come in a powder form prone to oxidative degradation, complicating storage, transportation, and downstream applications, thus necessitating granulation to stabilize their performance.

PP and PE powders are combined with additives like antioxidants and aging inhibitors. They are then processed in an underwater granulation system to become uniform pellets, which simplifies its storage and transportation.

They are then processed in an underwater granulation system to produce uniform pellets, which simplifies storage and transportation.- … system to become uniformed ( or equal) pellets, which simplifies its storage and transportation

Operation Scope：

Granulation of powders such as PP,PE.
