Electrolube ER2224, UR5638 and UR5639 encapsulation resins

Electrolube develops, manufactures and supports a wide variety of resin products. One of the company’s latest epoxy resins is the epoxy ER2224, a modified formulation of the ER4001 thermally conductive epoxy resin system, which offers an improved method of cure and subsequent health and safety benefits for the user.

The resin is particularly suited to automotive applications (for both traditional and electric power train types) that generally require high thermal conductivity and good thermal cycling performance. The resin is also suitable for use in LED lighting units where it helps to promote heat dissipation and prolong unit service life.

Electrolube is also launching two polyurethane resins which are specifically aimed at helping LED lighting manufacturers provide environmental protection for their products. UR5638 is a tough, low-exotherm product, providing a clear, transparent finish. The low exotherm of the resin makes it particularly suitable for applications involving the encapsulation of larger LED lighting units. It is an aliphatic polymer offering good UV stability and transmission of visible light, making it a suitable resin for white light LEDs.

UR5639 is a low-exotherm, low-viscosity, low-hardness, flexible, clear/transparent resin designed for encapsulating a variety of electrical components — particularly LEDs. The level of flexibility achieved by the cured resin means that the connecting legs of components are not placed under high levels of stress during the cure.
