DOPO Chemical Properties:

9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide also known as 9,10-dihydro-9 -oxa-10-phosphaphenanthrene-10-oxide (DOPO) , is an important new reactive phosphorus flame retardant. The flame retardants synthesized by DOPO and its derivatives have the characteristics of high efficiency, halogen-free, smoke-free, non- toxic, non-migrating, and durable flame-retardant properties.

DOPO CAS:35948-25-5 Application:

1.It is used as antibacterial agent, antioxidant, anti-fading agent, flame retardant, and reactant when synthesizing monomers. At present, in the field of flame retardants, DOPO is widely used as a new generation of halogen- free, environmentally friendly and green flame retardant modified monomers. DOPO is mainly used in the fields of flame retardant, special functional polymers, epoxy resins, luminescent materials, modified materials, etc., especially in the field of electronic and electrical materials, especially in the field of electronic and electrical materials. In order to meet the requirements of environmental protection, DOPO epoxy resin will gradually replace brominated epoxy resin as an environmentally friendly material in the copper cladding industry.

2.At the same time, the polymer modified with DOPO has the excellent advantage of not requiring flame retardant modification again. In terms of luminescent materials, DOPO can be used to modify luminescent materials to synthesize a new generation of polymers with excellent thermal stability, flame retardancy and physical and mechanical properties to manufacture liquid crystal panels.
