Weifang Kaihong Chemical Ltd. produces 1,2,5,6,9,10‑Hexabromocyclododecane, commonly abbreviated HBCD, a brominated flame retardant used in polymer applications. The chemical is supplied as a white powder or fine particles with a typical particle size of 2‑5 µm and carries the CAS number 3194‑55‑6. Its molecular formula is C12H18Br6 and the molecular weight is 641.7 g mol⁻¹, values that are standard for this compound. The product is packaged in 25 kg bags, 1 tonne big bags or 900 kg bulk containers for bulk shipments.

Key technical parameters include a bromine content of 74 % and a typical purity of 98 % for industry‑grade material. The melting range is reported between 175 °C and 185 °C, with a TGA decomposition temperature around 240 °C, indicating good thermal stability for polymer processing. Additional specifications list volatile matter not exceeding 0.5 % at 105 °C after 2 h, a hue APHA value of 30, conductivity up to 70 µS cm⁻¹, and a pH of 6.5‑8.5 in a 5 % aqueous solution. Insoluble substances are limited to 1 % and the material dissolves rapidly within three minutes when pure, a behaviour typical for HBCD grades used in flame‑retardant masterbatches.

The primary applications are as a flame retardant in expanded polystyrene (EPS), extruded polystyrene (XPS), textile and polymer masterbatches, where its bromine content provides effective fire resistance. Buyers such as polymer manufacturers, building material producers and textile finishers source HBCD in bulk for blending into resin formulations. Trade can be arranged on CIF or FOB terms, with flexible packaging sizes, but buyers should confirm exact shipment volumes, incoterms and any required safety data sheets before finalising the purchase.

Weifang Kaihong Chemical Ltd. is located in the Binhai Economic Development Zone of Weifang, Shandong Province, China. The company is classified as an imported‑tier supplier and holds a harbour‑level trust tier, indicating a verified business profile despite a recorded response rate of zero, so communication may require additional follow‑up. Its public profile lists the address and indicates activity in the chemical export market, focusing on specialty flame‑retardant compounds.

The supplier offers standard bulk packaging options such as 25 kg bags, 1 tonne and 900 kg big bags, which are common for large‑scale chemical shipments. No further corporate history, employee numbers or client references are provided, so buyers should request any additional corporate or compliance documentation directly from Kaihong before transacting.
