Asphalt inhibitors

■Product Overview
SDI bitumen inhibitors are mainly composed of polymers containing polar groups. Large molecular weight polymers contain oil-soluble alkyl chains and polar groups that can interact with asphaltenes, forming an oil-soluble stable layer around asphaltenes, inhibiting the interaction between asphaltene molecules, and preventing asphaltene flocculation and deposition.
