About us

G&B Seven Limited was established in 1998. The founder Mr. William Guo developing phosphorus copolymerized flame retardant CEPPA and phosphorus blended flame retardant AP-PSI depending on his research results in college which are applicable to all kinds of fibers and fabrics, is the pioneer in this industry. Since 2003, we have cooperated with the famous chemistry college of Sichuan University and developed photoinitiator, phenolic antioxidant and foaming agent series products. In particular, the photoinitiator series products are initiated in China with international level technology. They are widely applicable to UV-curable varnish and colored paint system, such as woodware, paper, metal, plastic, fiber, printing ink and so on. Phenolic antioxidant series products adopt innovative technology with completely independent intellectual property to produce 2-tert-Butyl-4-methylphenol，6-tert-Butyl-m-cresol and so on by crude phenol. Compared with the traditional technology, we have better quality, but lower price. Foaming agent series products are mainly ADC foaming agent adjustive additives. They can improve the gas evolution of ADC foaming agent, improve decomposition speed and lower decomposition temperature, widely applicable to PVC foaming leather and PVC shoe material. …...
