Electrolube Launch New Encapsulation Resins at Electronex
Posted on 02 September 2016 by Electrolube
Global electro-chemicals manufacturer, Electrolube, develops, manufactures and supports a wide variety of resin products and will showcase a new era of encapsulation resins on Stand B12 at Electronex electronics design and assembly expo at the Australia Technology Park in Sydney, 14-15 September.
One of the latest epoxy resins from Electrolube, which will be featured at Electronex 2016, is a modified formulation of the company’s ER4001 thermally conductive epoxy resin system, offering an improved method of cure and subsequent health and safety benefits for the user. This 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 improved ER4001 is also ideal for use in LED lighting units where it helps to promote heat dissipation and prolong unit service life.
Electrolube’s epoxy resin portfolio includes a variety of clear, white and black single- and two-part products with a host of useful properties to meet most requirements from potting and sealing to dipping, including exceptional electrical and thermal characteristics, flame retardancy and resistance to chemicals and fuels.
Electrolube will also launch two new polyurethane resins at Electronex, which are specifically aimed at helping LED lighting manufacturers provide environmental protection for their products. UR5638 is a tougher and low exotherm version of its 5634 product, providing a clear, transparent finish. The low exotherm of this resin makes it particularly suitable for applications involving the encapsulation of larger LED lighting units. It is an aliphatic polymer offering superior UV stability as well as excellent transmission of visible light, making it an ideal resin for white light LEDs.
The second new polyurethane resin to be showcased at the show (UR5639) is a low exotherm, low viscosity, low hardness, flexible, clear/transparent resin designed for encapsulating a variety of electrical components, but 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.
Electrolube's polyurethane resins come in white, black, blue, clear straw, hazy/cloudy and optically clear formulations and, in common with the epoxy range, offer a host of properties to meet the needs of high-temperature environments and those exposed to chemical contamination, mechanical stress or shock and moisture ingress.
As with some types of polyurethane resin, optically clear silicone resins, such as Electrolube's SC3001, have superior resistance to UV light, and have been shown to maintain their clarity throughout rigorous laboratory exposure testing regimes. This well-documented UV resistance makes them ideal for LED applications where resin colour stability is important to achieving minimal colour temperature shift of the LED lighting unit itself.
The majority of Electrolube resins are two part systems that, when mixed together in the correct ratio, react to form polymeric materials. By careful formulation, the properties of the cured resin can be tailored to meet individual customer requirements.
