In modern construction and materials engineering, XPS (extruded Polystyrene foam board) and EPS (expanded polystyrene foam board) are widely used in insulation, heat insulation and other fields. Due to their excellent heat insulation performance and relatively low cost, XPS and EPS have become indispensable materials in the construction industry. At present, instead of hexabromocyclododecane (HBCD), brominated SBS (brominated styrene-butadiene-styrene copolymer) is more widely used as a flame retardant in XPS and EPS materials.
As an excellent alternative to HBCD, brominated SBS performs outstandingly in performance. It not only meets the multi-faceted requirements of the environment, health and safety, but also has flame retardant performance comparable to HBCD, adapting to the flame retardant standards of various regions around the world (such as the European Union, the United States, Canada, etc.). Meanwhile, brominated SBS can also effectively maintain the physical properties of EPS and XPS foams, meeting the requirements of foam characteristics. During the production process, it also performs well, meeting the stability requirements of EPS and XPS, and is cost-effective and suitable for industrial production. More importantly, its mechanical properties have been improved compared to HBCD and are even more superior.
After rigorous environmental, health and safety assessments and tests, brominated SBS has demonstrated extremely low ecological risks and biological toxicity. Its unique macromolecular properties ensure that it cannot penetrate the cell membrane, which avoiding entering the organism. In the market, products containing brominated SBS not only meet people's expectations for exterior wall insulation materials, but also meet market requirements in multiple aspects such as density, compressive strength, fire resistance, water absorption, flexural strength, thermal stability and zero VOC emissions. They are suitable for various building scenarios such as house walls, roofs, underground and cold storage.
