  • Radial (SI)n block copolymer.
  • Contains ~78% SI diblock copolymer.
  • Low styrene.

VECTOR 4187A styrenic block copolymer is a radial block copolymer with a narrow molecular weight distribution. It is well-suited for use in low viscosity hot melt pressure sensitive adhesive applications requiring excellent adhesion to low energy surfaces, low migration characteristics, and enhanced die-cutting characteristics.

  • VECTOR 4187A (SI) n is offered as a dense pellet supplied from the United States.
