BROMINATED POLYSTYRENE-POLYBUTADIENE TRI-BLOCK POLYMER
SR-105 is a brominated polymerized flame retardant. It contains aliphatic bromine similar to HBCD, but it has ahigher molecular weight (molecular weight is about 100000), which is not easy to penetrate the cell membrane,and is not easy to cause harm to human body and environment. When applied to exterior wall thermal insulationmaterials, has the advantages of no frost, no migration, high thermal stability and environmental friendliness.
