Product introduction
Product features
It has the characteristics of high elasticity, easy processing, easy blending, and the remaining materials can be reused. Compared with styrene-butadiene block copolymer (hereinafter referred to as SBS), SIS has better cohesion, excellent adhesion properties and better compatibility with other additives. It is used in the preparation of hot melt pressure-sensitive adhesives. field, with unique and excellent performance that is unmatched by SBS. At the same time, the viscosity and melt viscosity of SIS solution are small, and the processing performance of SIS is better than that of SBS.
