Poor melt flowability of MBS-modified PVC
Sorun Belirtisi
Melt flowability of MBS-modified PVC is poor, extrusion or injection is difficult, and processing efficiency is low
Neden Analizi
Excessive MBS addition increases melt viscosity
Processing temperature too low, below the 180-220°C lower limit
Insufficient PVC/MBS compatibility, uneven melt
Lubricant system mismatch
Screw design not suitable for PVC/MBS blending
Çözüm
Reasonably control MBS addition amount
Appropriately increase processing temperature to the 180-220°C range
Select MBS models with good compatibility
Optimize the lubricant system
Use a screw design suitable for PVC
Temel Çıkarım
MBS-modified PVC flowability needs ratio and lubrication optimization
