4,4'-Biphenol is mainly used for the preparation of rubber antioxidants, plastic antioxidants, and engineering plastics. Its specific applications are as follows:
Rubber and plastic additives:
As an anti-aging agent, 4,4'-Biphenol can prevent aging caused by oxygen and heat, and is suitable for colorless vulcanized rubber products, rubber products for food packaging, and medical latex products. It has a protective effect on harmful metals. As an antioxidant, 4,4'-Biphenol is mainly used for heat-resistant plastics such as polyester, polyurethane, etc. ‌
Engineering material modification:
4,4'-Biphenol is used to prepare modified monomers such as polysulfone resins (such as polyphenylsulfone) and epoxy resins. Due to its heat resistance, oxidation resistance, and non toxicity, it is suitable for high demand fields such as aerospace, automotive components, and medical devices. ‌
Dye intermediate:
4,4'-Biphenol is used as a precursor for the synthesis of photosensitive materials, for the preparation of special dyes or photosensitive compounds. ‌
Preparation of polyetheretherketone copolymer:
4,4'-Biphenol is copolymerized with raw materials such as hydroquinone and difluorobenzophenone to enhance the material's temperature resistance and oxidation stability, making it suitable for high-temperature environments.
