Flame Retardant for PP BDDP 21850-44-2
The flame retardant BDDP (tetrabromobisphenol A bis(2,3-dibromopropyl ether)) is a brominated organic compound with CAS number 21850-44-2 and molecular weight 943.62. It appears as a white powder with a melting point of 105 to 115°C and a bromine content of at least 67%. It is insoluble in water and methanol but soluble in dichloromethane and toluene, making it suitable for use in polymer compounding processes.
This compound is widely used as a high-efficiency flame retardant for polypropylene, particularly where high thermal stability and low smoke emission are required. It is also applied in PS, ABS, and rubber compounds. Typical industry standards for brominated flame retardants in PP require bromine content above 65% and low volatile loss. The carbonization temperature of 240°C minimum ensures stability during processing without premature decomposition.
Buyers in the automotive, electronics, and appliance industries use BDDP to meet flammability requirements for PP housings and structural parts. It is commonly supplied in 25kg kraft paper bags and stored in dry, sealed conditions. Trade terms are typically FOB Qingdao, with lead times dependent on production cycles. No MOQ is stated; buyers must confirm directly.

Sourcing Flame Retardant for PP BDDP 21850-44-2 from Shandong Yubin Chemical Co., Ltd - China Import Guide
Before ordering, request a certificate of analysis confirming bromine content, melting point, and volatile matter levels. Verify that the product is free from restricted substances such as PBDEs or hexabromocyclododecane, even if not explicitly labeled. Confirm batch-to-batch consistency through sample testing, as purity affects flame performance in PP.
Confirm Incoterms with the supplier - FOB Qingdao is standard. Lead time is typically 20 to 35 days, but no data is provided. Payment terms are usually T/T in advance or L/C at sight. Packaging must be moisture-proof, and bags should be labeled with batch number, CAS, and net weight for customs and traceability.
Perform a UL94 V-0 or V-1 test on final PP parts to validate flame retardancy. Check for surface bloom or discoloration under magnification. Request a material safety data sheet (MSDS) and ensure proper handling procedures are followed due to bromine content. Retain a sample from each shipment for future quality audits, especially in regulated industries.
