PLA and PBAT Blending
Sorun Belirtisi
The toughness of PLA/PBAT blend film is improved, but phase separation causes uneven performance
Neden Analizi
PLA is brittle and PBAT is flexible, and blending can balance rigidity and toughness; but the two have poor compatibility and easy phase separation; a compatibilizer is needed to improve the interface; the blend ratio determines the performance orientation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
①Add compatibilizer in blending to improve compatibility; ②Optimize the ratio per rigidity-toughness requirements; ③The blending process ensures uniform dispersion; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PLA/PBAT blending is the mainstream formula for degradable films; the compatibilizer is the key to performance uniformity; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
