Core Advantages of Senthos Brominated SBS
-
Sustainable HBCD Alternative: As a high-molecular-weight Brominated SBS, ST-970 does not penetrate cell membranes, making it environmentally friendly and safer for human contact compared to traditional EPS Flame Retardants.
-
Zero Migration & No Frost: Its polymeric structure ensures that the Brominated SBS remains locked within the EPS matrix. Consequently, it eliminates the “frosting” and migration issues common with low-molecular-weight additives.
-
Superior UV & Thermal Stability: ST-970 is engineered to withstand high temperatures during extrusion (up to 250°C), ensuring the long-term durability of external wall insulation materials.
-
Global Regulatory Compliance: Our Brominated SBS is the future-proof choice for manufacturers looking to comply with REACH and other eco-labels.
Packaging, Storage & Global Logistics
-
Packaging Options: 15kg/bag, 500kg/bag, or customized jumbo bags according to your specific requirements.
-
Storage Requirements: Store this Brominated SBS in a cool, dry, and well-ventilated area. Keep the packaging tightly sealed to prevent moisture from affecting the EPS Flame Retardant performance.
