PASTE PVC
Process and technology route:
PPVC polymerization process: Micro-suspension technology
PPVC technology: Introduced from Kaneka Corporation (Japan) in 1987.
Capacity: After more than twenty year's development, PPVC has became our key product with the capacity of 13 ktpa.
Technological characteristics of micro-suspension copolymerization:
Process is simple and ripe
Can control accurately the granularity of the product, good repeat in production, and stable quality
Lower paste viscosity, and allows use of more fillings to reduce end users’ cost
Product paste viscosity has excellent storage property
