PVC Soft Extrusion Temperature
Sorun Belirtisi
Soft PVC after extrusion shows plasticizer exudation, surface greasy, performance decline
Neden Analizi
Soft PVC processing temperature 130-170℃, lower than rigid; too high temperature causes plasticizer volatilization and exudation, surface greasy and material hardens; temperature window needs adjustment by plasticizer content
Çözüm
①Soft PVC temperature 130-170℃; ②Prevent local overheating causing plasticizer loss; ③When exudation severe, check formula and temperature matching; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Soft PVC temperature management must also protect plasticizer; overheating loses not only appearance but also flexibility; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
