Specification:

Item
Index
Appearance
White crystal or powder
purity
≥99 %
content
≥14.0%
Melting point
≥114°C
Application
: DOPO contains a rigid phosphorus group and thus provide better thermal
and flameretardant properties than the conventional epoxy resins prepared from tetrabromobisphenol A.
The advanced epoxy resins are suitable for making a fiber-reinforced
epoxy resin
composite
which
is useful in the fabrication of printed circuit boards.
The cured
epoxy resins can be used in semiconductor encapsulation applications.
