PET Chip WK-621

WK 621 does not undergo solid-phase adhesion process. It can be reprocessed to increase adhesion to produce WK-821. It can also produce vials that do not require particularly high strength and quality.

Features: 

  • Lower viscosity, good color, slightly low molecular weight and stable distribution
  • Excellent processing performance and compatibility
  • Good injection molding fluidity and high production stability.

Typical applications: Basic PET for WK-621

 

WK-621 has low viscosity, good transparency, good injection fluidity and high production stability. It is the basic PET for producing WK-821. It can also produce vials that do not require particularly high strength and quality.
