Thermally conductive epoxy resins for LEDs

PIN FRs enable fire performance, low smoke and fumes, transparency and thermal conductivity for LEDs. Electrolube, a global formulated chemical supplier since 1941 to electronics and industry, has developed innovative thermally conductive flame retardant epoxy resins. The white ER2074 resin uses PIN flame retardants to achieve UL94-V0) with low smoke and fumes. The resin is thermally conductive (1.26 W/m.K), does not contain abrasive fillers so is processing friendly, and offers high water and chemical resistance. Its white colour after curing offers appearance advantages and combined with its thermal conductivity makes it ideal for applications in LED lighting, both internal and external. Electrolube has now announced a first transparent UL94V-0) resin, UR5641, again using PIN flame retardants, and using aliphatic urethane chemistry resistant to yellowing. It offers thermal conductivity of 0.35 W/m.K and operating temperatures -40 to 120°C.
