Low Viscosity Flexible Asphalt
Low Viscosity Flexible Asphalt
Selecting premium South American and Middle Eastern naphthenic crude oils for our asphalt production, our products boast numerous advantages including low viscosity, excellent compatibility, superior four-component properties, non-brittleness at -26°C, and strong adhesive strength. In comparison to conventional waterproof asphalt products, our asphalts enable downstream companies to reduce their coil production temperatures by 10°C, leading to significant energy savings and consumption reduction. With a deep understanding of waterproofing customer requirements, we have established the "Low-Viscosity Flexible Asphalt" corporate standard and introduced products that align with this benchmark.
Advantages
1. Raw material advantages: We selected South American and Middle Eastern naphthenic crude oil as raw materials to produce asphalt products with low viscosity, four-component superiority, and good compatibility with modifiers and other additives;
2. Performance advantages: Low viscosity, excellent low-temperature performance (-26C brittling proof), great bond strength; compared with ordinary waterproof asphalt products, they can reduce the coil production temperature by 10 ℃;
3. Standard: With an insight into the needs of waterproofing customers, we released the "Low-Viscosity Flexible Asphalt" corporate standard.
Low temperature flexibility: ＞-26℃
Reduce the coil production temperature: 10 ℃
Applications
Waterproofing asphalt membrane (coating material), non-curing waterproofing coatings
