Application

1. Polymerization inhibitor for polymerizable monomers

p-Tert Butylcatechol (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.

2. Antioxidant

p-Tert Butylcatechol (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.

3. Stabilizer for various organic compounds

p-Tert Butylcatechol (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.
