Applications

Polymerization inhibitor for polymerizable monomers

TBC is used as a polymerization inhibitor and stabilizer for polymerizable monomers such as styrene and butadiene and is added during the manufacturing process or to products that require transportation and storage.

Antioxidant

TBC is effective as an antioxidant for a wide range of chemical compounds including polymers such as polyethylene, polypropylene, polychloroprene, synthetic rubber, and nylon, as well as oils and their derivatives, ethyl cellulose, lubricating oil, and caprolactam-maleic anhydride and tin metallic soaps.

Stabilizer for various organic compounds

TBC, in combination with epoxy compounds or alcohol, displays excellent properties as a stabilizer for chlorinated hydrocarbons like trichloroethylene and perchloroethylene. When producing plasticizers by the esterification of polybasic acids and oxo alcohols, there is a color protection effect if TBC is added, and a plasticizer with good color stability can be obtained.
