Product Description
4,4'-Dichlorodiphenyl sulfone, code as DCDPS, CAS No.: 80-07-9, is a key monomer for the preparation of high-performance polyarylether engineering plastics such as polyethersulfone (PES), polysulfone (PSU) and polyphenylsulfone (PPSU).
Product properties & Features
1. It appears as white crystalline powder with high purity(99.7%min). It features excellent thermal stability, high temperature resistance and thermal decomposition resistance.
2. The sulfone group (—SO₂—) in the molecular structure possesses extremely high chemical stability, showing outstanding hydrolysis resistance, acid and alkali resistance, chemical corrosion resistance and aging resistance.
3. The para-chlorine atoms have high chemical reactivity, which readily undergo nucleophilic substitution polycondensation with bisphenol monomers, with mature and controllable polymerization processes.
4. Its rigid molecular structure endows synthetic resins with excellent comprehensive properties including high strength, high modulus, high and low temperature resistance, flame retardancy and good electrical insulation.
5. The resultant products feature high long-term service temperature, excellent dimensional stability and outstanding creep resistance.
Applications
