ANTIOXIDANT HONOX-BBM is soluble in organic solvents. BBM has excellent oxidation resistance. BBM is used as stabilizer and antioxidant for polymers (ABS,PP,PE,PVC,SBS and PAN),synthesis rubber. It has a good synthesis effect in combination with thioesters antioxidants (DLTDP,DSTDP) and UV absorbers. It is no pollution, no discoloration. It wonot decompose under high temperature process. On the other hand BBM also has metal ionic passivation function and applys in polyolefin and cable production.
