Rubber Modifiers: Rubber is a polymer material with high elasticity and stretchability over a wide temperature range, including natural rubber and synthetic rubber. Representative varieties are SBR, CR, EPDM, waste rubber powder. It as a bitumen modifier generally gives good stability to modified asphalt. Thermoplastic resin modifier: can be repeatedly heated to soften (or melt) and cooling solidified resin, usually linear polymer. Representative varieties are EVA, PE, PP and so on. Thermoplastic resins, as bituminous modifiers, generally impart good high temperature performance to modified asphalt. Thermoplastic elastomer Modifier: Thermoplastic elastomer, also known as thermoplastic rubber, both rubber and thermoplastic properties, at room temperature shows the rubber elasticity, when heated plastic material is high. According to the nature of cross-linked chemical cross-linked and physical cross-linked type, can also be divided into structural characteristics of block copolymers and graft copolymers. Representative varieties are SBS, SB, SIS and so on. Thermoplastic elastomers generally impart good high and low temperature performance to modified asphalt.
