CAS 4415-87-6
Introduction of the Polyimide
Polyimide (sometimes abbreviated PI) is a polymer of imide monomers. Polyimides have been in mass production since 1955. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles. A classic polyimide is Kapton, which is produced by condensation of pyromellitic dianhydride and 4.4'-oxydianiline
Feature of CAS NO.4415-87-6 CBDA
1. Excellent thermal stability
2. Good chemical resistance
3. Stable mechanical properties
4. Polyimide does not require the addition of flame retardants to prevent combustion.
Preparation Method:
tetrahydrocyclobuta[1.2-c:3.4-c ‘]difuran-1.3.4.6-tetraone can be prepared by the oxidation reaction of cyclobutanetetracarboxylic acid. First, cyclobutanetetracarboxylic acid is dissolved in an acidic condition, and then an oxidizing agent such as hydrogen peroxide, nitric acid, etc. is added to perform an oxidation reaction to obtain the tetrahydrocyclobuta[1.2-c:3.4-c ′] difuran-1.3.4.6-tetraone.
Safety Information:
tetrahydrocyclobuta[1.2-c:3.4-c ‘]difuran-1.3.4.6-tetraone currently has no public special security risk report. However, during handling and use, it is still necessary to take appropriate safety precautions, such as wearing appropriate protective gloves and goggles, and ensuring that the operation is carried out in a well-ventilated place. Avoid inhaling its dust or gas, avoid direct contact with the skin and ingestion. In case of any accident, the doctor’s help should be sought immediately.
