White powder, molecular weight 382.58, melting point 208ºC, acid, soluble in organic solvents. BBM has excellent antioxide performance, BBM is used as stabilizer and antioxidant for polymers(ABS,PP, PE, PVC, SBS and PAN), synthesis rubber and has a good synthesis effect in combination with thioesters antioxidant (DLTDP, DSTDP) and UV absorbers. No pollution discoloration, and decompose under high temperature process. On the other hand BBM also metal ionic passivation function and apply in polyolefin and cable production. The dosage is 0.05-0.5%.
