Cast Film Extrusion

Cast Film Extrusion: Solving High-Temp Stability

In the R&D of cast film extrusion using novel engineering plastics, maintaining material stability during high-temperature processing remains the central challenge. These advanced materials typically require processing temperatures between 250°C and 400°C, making them highly susceptible to molecular chain degradation and fluctuations in melt properties. Such issues frequently result in film scrapping due to discoloration, embrittlement, and […]
