PBD shear rate Regulation and Processing Stability
Fenómeno del problema
PBD exhibits shear rate-related process abnormalities in extrusion blending.
Análisis de la causa
Under the PBD processing temperature of 140-180°C, improper setting of the shear rate parameters leads to Mooney viscosity drift.
Solución
Optimize the shear rate and shorten the residence time.
Conclusión clave
In PBD processing, shear rate control is the foundation of quality stability.
