What are the reasons for high temperatures in polypropylene products?
Thread Content
Recently, high-temperature polypropylene products have been produced; I would like to know the reasons for this! What temperature affects product quality!
The uneven release of catalyst activity leads to high polymerization temperatures； As the temperature rises and heat is not removed in a timely manner, the catalyst activity increases further (catalyst activity is closely related to the polymerization temperature)
Add an inactivation step to prevent uneven reaction.
