Flame retardant, a functional additive that gives flammable polymers flame retardancy, mainly designed for flame retardant polymer materials; There are many types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the method of use.

Additive flame retardants are added to the polymer by mechanical mixing method to make the polymer flame retardant, and the additive flame retardant mainly includes organic flame retardants and inorganic flame retardants, halogenated flame retardants (organochlorides and organic bromide) and non-halogen. Organic is bromine, phosphorus and nitrogen, nitrogen, red phosphorus and compounds as the representative of some flame retardants, inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flame retardant systems.

Reactive flame retardant is used as a monomer to participate in the polymerization reaction, so the polymer itself contains flame retardant components, and its advantage is that the performance of the polymer material is less affected and the flame retardant is strong.

Dongguan Hongtaiji Flame Retardant Materials Co., Ltd. is a national high-tech enterprise (Shenzhen Hongtaiji Industrial Co., Ltd. brother enterprise) The company was established in 2004, the plant covers an area of about 10,000 square meters, well-equipped, the company's existing technology research and development personnel more than 20 people, workers 50 or 60 people.

In 2004, Hongtaiji began to develop and sell flame retardant industry products. By the end of 2007, the business covered 27 cities focusing on the three major urban economic circles of the Pearl River Delta, the Yangtze River Delta and the Bohai Rim. As of 2012, the company's business scope has basically covered 90% of the country, including Taiwan Province, Hong Kong and Macao Special Administrative Regions. In 2016, the products have been exported to South Korea, Japan, Russia, Europe and the United States. It has been well received by customers. In December 2017, it was recognized as a national high-tech enterprise. In 2023, it will be awarded the title of "specialized, special and new" enterprise.

Hongtaiji has been professional in flame retardant for 20 years, and its products meet international environmental protection requirements: (1) EU ROHS directive (2) REACH regulatory standards. Obtained ISO9001:2015, ISO14001:2015, ISO45001:2018 management system certification. Independent research and development of melamine cyanurate (MCA), microencapsulated red phosphorus, melamine pyrophosphate (MPP), polyolefin halogen-free flame retardant, cable heat shrinkable tube flame retardant, glue tape flame retardant, acid fire retardant coating, acrylic flame retardant, and a number of environmentally friendly flame retardants.
