Technical Data Sheet

 

SBS-4412

 

Styrene-Butadiene-Styrene block copolymer

 

SBS-4412 is a copolymer made by anionic polymerization from butadiene and styrene in a hydrocarbon solvent using organic lithium as the imitator. It appears as white or light color porous particles with round rod or wafer shape and possesses the advantages of both rubber and plastic with excellent wet-skid resistance and low temperature endurance,good elasticity,remaining materials can be used recycled for many times,can save resources and conductive to environment protection,easy to be colored. It is widely used in footware,adhesive,modification of higher polymer and toys.
