We help you source Hexabromocyclododecane(HBCD) in China

Our Advantages:

We have been in the flame retardant business since 2008 and currently work with 8 factories located in Shandong, Inner Mongolia etc. Since 2008, we have supplied various flame retardants to over 60+ customers, including Albemarle, Kolon, Hanwha, Lanxess, etc.

We have a 20+ year track record of working with suppliers in China and rating reports on them, and we keep our suppliers updated with the latest news so our customers can get the latest supplier reports. We know the market well and have early warning notifications on upstream raw material prices to help you build a stable supply chain.

When selecting suppliers, our procurement specialists will audit the qualification of suppliers, conduct thorough investigations such as field visits and sample testing, and make ratings to ensure the authenticity and legality of supplier information.

We have a long-term stable cooperation with GLP laboratories, encounter customer test results and supplier test results do not match the situation, we will commission a third party to test to ensure the accuracy, authenticity and reliability of the experimental results. In this way, we can effectively control the product quality problems.

We have a long-term cooperative warehouse and can follow up packaging and labeling according to safety regulations and customer requirements. In order to effectively prevent damage to the goods in transit, we have prepared various reinforcement measures and packaging solutions.

We have a number of international freight companies with whom we have long-standing cooperation, and we can choose several route options according to the customer's requirements. For more difficult or urgent orders, we will prepare several alternative solutions to ensure safe and timely delivery.

Hexabromocyclododecane, often shortened to HBCD, is a cyclic low-molecular-weight hydrocarbon that is colorless, odorless and tasteless. It was the most popular do-it-yourself reductive agent for PVC pipes, but it is identified as a major contributor to climate change.

Several countries are now imposing strict regulations on its use. It is a powder, and the smallest particle size characteristic of this product is approximately 1 µm.

It can be produced on a large scale by reacting cyclohexene with bromine in an electrodeless discharge process. The properties of Hexabromocyclododecane make it especially useful in manufacturing plastic resins and polyurethanes.

Thanks to its low toxicity, repetitive exposure of workers is believed not to cause any major health effects like trihalomethanes (THMs) or polybrominated mixtures (PBBs).


Hexabromocyclododecane (HBCD) has served as a flame retardant in plastics because it reacts readily with the hydrocarbon oxidized during combustion.

HBCD spreads quickly throughout consumer items made from polymer materials through product contamination--packaging features contaminated by chemical processing components are notorious sources of carcinogenic substances.

Applications for Hexabromocyclododecane are diverse. It is used to make polyurethane foam, soundproofing material, insulation, varnish for roofs and furniture, protective coatings for textiles. It is also used as an industrial chemical to manufacture other chemicals, polyester resins, and metalworking fluids.

Given it has great thermal stability, low vapor pressure, low volatility, good acidic resistance and good thermal stability makes HBCD useful as a feedstock for other compound production.
