Polypropylene T501 temperature
Thread Content
Why is the temperature for polypropylene T501 controlled above 80°C? What other purpose does it serve besides providing a heat source for E303?
Keeping the temperature of polypropylene at above 80°C not only provides a heat source for E303 but also helps to improve the fluidity and processing efficiency of polypropylene. It simultaneously reduces the viscosity of the material during processing, facilitating molding and fabrication. .

Hello, teacher. I have a question. One of the factors that affect the activity of propylene catalysts is the monomer partial pressure. What does this monomer partial pressure mean?
Hello! The monomer partial pressure generally refers to the partial pressure of a specific monomer (in this case, propylene) within the reaction system during the catalytic reaction process. It is the proportion of the pressure exerted by that individual gas in the gas mixture. The partial pressure of propylene directly affects the activity of the catalyst and the efficiency of the polymerization reaction. The higher the partial pressure, the greater the concentration of propylene available to the catalyst, and generally the better the catalytic effect; however, it is also necessary to keep this pressure within an appropriate range to ensure the stable progress of the reaction. .
