G&B Seven Limited was established in 1998. The founder Mr. William Guo, a pioneer in this industry, building on his research at college, began developing phosphorus copolymerized flame retardant CEPPA and phosphorus blended flame retardant AP-PSI, which are applicable to all kinds of fibers and fabrics.

Since 2003, we have cooperated with the famous chemistry college of Sichuan University and developed a series of photoinitiator, phenolic antioxidant and foaming agent products. In particular, the photoinitiator series products are the very first in China to be produced with international level technology. They are widely applicable to UV-curable varnish and colored paint systems, such as woodware, paper, metal, plastic, fiber, printing ink and so on.   

Our phenolic antioxidant series products adopt innovative technology with completely independent intellectual property rights to produce 2-tert-Butyl-4-methylphenol，6-tert-Butyl-m-cresol and so on from crude phenol. Compared with the traditional technology, we have better quality, but at a more competitive price.

Foaming agent series products are mainly ADC foaming agent adjustive additives. They can improve the gas evolution of ADC foaming agents, improve decomposition speed and lower decomposition temperature; they are widely applicable to PVC foaming leather and PVC shoe material.

Since 2009, we have established a national engineering laboratory with 3 PhDs, 12 Masters and 21 college graduates. Supported by such a strong research and development capability, we are constantly launching new technologies and products, possessing the capacity for sustainable development.   

We concentrate on technology research and development, serve the global market and are gradually becoming an international and domestic well-known enterprise.     

We conscientiously provide high quality products and first-class services for every customer.  

Choose G&B, choose success.
