Vultac® TB7 by Arkema is poly-tert-butylphenoldisulfide. Acts as a nitrosamine-free vulcanizing agent. Also acts as an antioxidant because of its phenolic structure. Low molecular weight alkyl phenol disulfide oligomers that contain between 20-32% sulfur. Offers high elastomer solubility. Vultac forms monosulphide bridges which are more stable and have very good resistance to heat and ageing when compared with typical polysulfide bridges. Vultac® TB7 is used for polymers like rubber and in tire industry applications.
