Thermoplastic elastomers (SBS)
SBS thermoplastic elastomers are highly elastic polymers (synthetic rubbers) that give bitumen flexibility at low temperatures. SBS coatings have excellent adhesion and high resistance to sudden changes in temperature (with a transition through 0 ° C). In addition, SBS-materials are highly elastic, frost-resistant, and also easily repeat the shape of the surface on which they are laid. When modifying bitumen using SBS, a polymer matrix is created, which in this case represents a three-dimensional network formed due to the interaction of polystyrene blocks in the so-called polystyrene domains. Within this elastomeric mesh, bitumen is dispersed as a fine dispersion.
