【 HBCD-75 】
1,2,5,6,9,10 - Hexabromo Cyclododecan
【 Chemical Structure 】
【 Introduction 】
HBCD-75 is a alicyclic flame retardant which has high bromine content. Its low filling property has a little effect on polymer's function, so as to guarantee the polymer's good function.
【 Characteristic 】
Molecular Formula: C12H18Br6
Specific Gravity: 2.24
Appearance: White or off-white powder crystal
【 Specification 】
HBCD total content: ≥99%
Melting point: ≥180°C
Bromine Content: ≥73%wt
Volatile Matter Content (105°C,2hrs): ≤0.5%wt
Average Particle Size: 2 – 4 microns
20 – 40 microns
【 Use 】
HBCD-75 mainly uses in those thermoplasticity and thermoset high molecular polymer which have flame-resistant request. The product has great quality when uses in polystyrene foam(EPS), the oxygen index(OI) may higher than 30 and reaches the stated self extinguishing standard. Meanwhile the product also has many advantages for other polymer systems, such the great heat stability, low addition level, and do not need to add other assistant flame retardant(Such as antimony oxide).
