Compare APP and SBS modified bitumen membranes performance
APP (Atactic Polypropylene) modified bitumen membranes are plastomeric, offering superior high-temperature stability and UV resistance, while SBS (Styrene-Butadiene-Styrene) membranes are elastomeric, providing greater flexibility and low-temperature performance. Performance Comparison Aspect APP Membranes SBS Membranes Flexibility/Elasticity Less flexible, especially in cold; limited elongation below freezing. High elasticity and crack-bridging; excels in cold climates down to -25°C. […]
