Overview
FR3008 is a brominated flame retardant belonging to the polybrominated diphenyl ether (PBDE) family. It is widely used in industrial applications to reduce flammability in materials such as plastics, textiles, and coatings. Its effectiveness stems from its ability to release bromine radicals during combustion, which interrupt the fire cycle. Due to environmental and health concerns, some regions regulate its use, but it remains a cost-effective solution for fire safety in specific applications. Manufacturers often blend FR3008 with polymers to meet fire safety standards without significantly altering material properties.
Physical and Chemical Properties
FR3008 is a white to off-white powder with a molecular weight of approximately 564.7 g/mol. It exhibits high thermal stability, with a melting point range of 250-300°C, and decomposes before reaching a boiling point. The compound is insoluble in water but dissolves readily in organic solvents like toluene and acetone. Its flame-retardant action is attributed to the release of bromine radicals when exposed to heat, which quench flames by scavenging free radicals. The density of FR3008 is around 2.2 g/cm³, and it has low volatility, making it suitable for high-temperature processing.
Main Applications
FR3008 is primarily used in the plastics industry to enhance the fire resistance of products such as electrical enclosures, automotive components, and consumer electronics. It is also incorporated into textiles for curtains, upholstery, and protective clothing to meet flammability standards. In construction, FR3008-treated materials are used in insulation and wiring to improve safety. The electronics industry relies on it for circuit boards and connectors, where fire resistance is critical. Its compatibility with various polymers makes it a versatile choice for diverse industrial needs.
Safety and Storage
FR3008 requires careful handling due to its brominated nature. Workers should use personal protective equipment (PPE), including gloves and masks, to avoid inhalation or skin contact. The compound should be stored in a cool, dry place, away from direct sunlight and moisture, to prevent degradation. Disposal must comply with local environmental regulations, as brominated flame retardants can persist in the environment. Suppliers often provide Safety Data Sheets (SDS) with detailed handling instructions. In case of accidental exposure, rinse affected areas with water and seek medical advice if necessary.
B2B Procurement Guide
When procuring FR3008, industrial buyers should prioritize suppliers with certifications such as REACH or RoHS compliance to ensure regulatory adherence. Bulk purchases typically offer cost advantages, but buyers should verify batch consistency and purity levels (e.g., ≥95%). Consider logistical factors like packaging (25 kg bags or drums) and lead times. Some suppliers provide technical support for blending FR3008 with specific polymers. For sustainable alternatives, inquire about halogen-free flame retardants, though these may come at a higher cost.
