VECTOR® 4186A

VECTOR® 4186A by TSRC Corporation is a high molecular weight styrene-isoprene radial (SI)n block copolymer. It is produced via proprietary anionic polymerization technology and contains 73% SI diblock copolymer. Vector™ 4186A is made with a patented coupling process that yields a polymer primarily with a 4-arm radial architecture. It is particularly suited for low-viscosity hot melt pressure sensitive adhesive systems having excellent adhesion to low energy surfaces, low migration characteristics and enhanced die-cutting characteristics within label stock applications.
