What is Weidun’s SBS Modified Bitumen Waterproofing Membrane?
Firstly, Bitumen production is cost-effective and is a residue from the crude oil distillation process, serving as a by-product after refining primary products such as gasoline, diesel, and high-octane fuels.
Additionally, bitumen is a versatile material. It exhibits viscoelastic and thermoplastic behavior, meaning its properties vary depending on temperature and loading duration:
At high temperatures or under prolonged loading, it behaves as a viscous fluid.
At low temperatures or under rapid loading, it acts as an elastic solid.
Meanwhile, bitumen has a relatively low melting point, making it easy to melt during application. Its strong adhesive properties enable robust bonding between materials. These characteristics make bitumen-based waterproofing one of the most widely adopted solutions in construction.
Weidun’s SBS Modified Bitumen Waterproofing Membrane exhibits exceptional high-temperature resistance, operating effectively within a temperature range of -25°C to +100°C. It boasts high elasticity, fatigue resistance, and outstanding mechanical properties, including an elongation rate of up to 150%, along with strong puncture and tear resistance. It is particularly suitable for cold climates and waterproofing projects in industrial and civil buildings prone to significant structural deformation or vibration.
