Several factors influence the performance of Flintlastic SA SBS modified bitumen in asphalt or bitumen modification systems. Key factors include the quality and type of SBS polymer used, the bitumen’s base properties, the processing temperature during modification, and the blending time. Additionally, the compatibility of the polymer with the bitumen, the presence of additives, and environmental conditions during application can significantly impact the final product’s durability, flexibility, and resistance to aging and UV exposure.
