  • SELF-EXTINGUISHING EPOXY RESIN FOR EPOXY MOLDING COMPOUND, METHOD OF PREPARING THE SAME, AND EPOXY RESIN COMPOSITION FOR EPOXY MOLDING COMPOUND.
    Publication number: 20150232658
    Abstract: A self-extinguishing epoxy resin for an epoxy molding compound (EMC) represented by Formula 1 is disclosed. The epoxy resin (composition) has excellent flame retardancy without using a halogen flame retardant or a phosphorous flame retardant. Upon comparison with NC-3000 that is one of the most widely and commercially available products of Nippon Kayaku Co., Ltd., the epoxy resin composition is a self-extinguishing epoxy resin for a high-end EMC having better or similar flame retardancy, excellent dimensional stability due to lower shrinkage rate, and ideal physical property balance with lower flexural modulus and higher glass transition temperature.
