Phosphorus Containing Epoxy Resin

Phosphorus-containing epoxy resins mainly include three types, namely DOPO type, DOPO-HQ type, and DOPO-NQ type. They are excellent in flame retardancy and heat resistance, and have low water absorption and expansion coefficient. They belong to halogen-free flame-retardant epoxy resin, and conform to RoHS and WEEE Directive. They are mainly applied in halogen-free flame-retardant printed circuit board, electronic copper clad laminate, electrical laminate, and other product fields.
