Flame-retarded thermosetting resin composition, prepregs and electrical laminates made therefrom. |
摘要 |
<p>A flame-retarded thermosetting resin composition is provided by blending about 5 to 45 mole % of a phenylcyanate having at least one halogen substituent at the ortho or para position relative to the cyanato group, and about 55 to 95 mole % of a halogen-free bis-4-phenylcyanate. A flame retardancy of V-O grade of UL94 is achieved in the thermoset resin of the composition without compromising dielectric, heat resistance, moisture absorption and other properties.</p> |
