A HALOGEN FREE FLAME RETARDANT EPOXY RESIN COMPOSITION
ES2566567
The present invention discloses a novel halogen free flame retardant epoxy resin composition with excellent mechanical properties, thermal resistance, fire retardancy, low smoke release and good processability. Its flame retardancy derives from the flame retardant halogen free phosphorous ingredient. Furthermore, the invention refers to the process of obtaining said epoxy resin composition. Moreover, the present invention relates to the use of the halogen free flame/fire retardant epoxy resin composition as adhesive. In addition, the present invention relates to articles comprising halogen free flame/fire retardant epoxy resin composition and their uses as an electric or electronic circuit component or a structural element for transportation and building.
IMDEA Materials has developed a new composition of a halogen-free flame-retardant epoxy resin with excellent mechanical properties, thermal resistance, good processability and low smoke release. The resin can also be used as an adhesive and to prepare pre-impregnated composite materials. Below, is a set of examples of the performance of these cured epoxy resins. Note that V0 stands for «burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed», which shows the outstanding fire suppression properties of these cured resins.
