How to choose pvc internal and external lubricants
1. The melting point of the internal and external lubricants of pvc is usually 50-60°C lower than the molding temperature.
 
  2. The fluidity, anti-adhesion and plasticization rate of the plastic must be properly balanced. Balance internal and external lubricants.
 
  3. Maintain the integrity of the lubrication effect in the early, middle and late stages of the system.
 
  4. No negative effects on secondary processing (heat sealing, lamination, printing, etc.).
 
  5. The lubricant has good dispersibility in the resin, and if necessary, a dispersant is added.
 
  6. Pay attention to the interaction with other additives (plasticizers, heat stabilizers, antioxidants, fillers, impact agents, etc.).
