Electrolube Launches New Encapsulation Resins at Electronex


Reading time ( words)

Electrolube will showcase a new era of encapsulation resins at the Electronex 2016 electronics design and assembly expo at the Australia Technology Park in Sydney on September 14–15.

One of the latest epoxy resins from Electrolube, which will be featured at Electronex 2016, is the epoxy ER2224, a modified formulation of the company’s ER4001 thermally conductive epoxy resin system, which offers an improved method of cure and subsequent health and safety benefits for the user. ER2224 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 new resin 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. UR3638 is a tougher and low exotherm version of its 3634 product, providing a clear, transparent finish. The low exotherm of the UR3638 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.

UR5639 is 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.

Is Your EMS Partner Up to Speed With WEEE 'Open Scope?'

10/23/2019 | Neil Sharp, JJS Manufacturing
E-waste encompasses a myriad of "unseen" metals, semi-metals, and chemical compounds that are found inside circuit boards, wires, and electrical connections. If not handled correctly, chemicals—such as cadmium, barium, lithium, lead, mercury, and beryllium—can present a significant health risk through direct contact, the inhalation of toxic fumes, or the build-up of toxins in water, soil, and food products.

Conformal Coatings

While conformal coatings may have been something of an afterthought at the front of the design process, that can no longer be the case. Conformal coatings are now a critical part of any board assembly that might be subjected to challenging conditions. But coatings can also contribute to increased mean time between failure in any conditions, even environmentally controlled environments.

Synergy Between Smart Manufacturing and the Secure Supply Chain (Part 1)

As MRP and ERP functions follow computing trends and start to migrate into the cloud, a fundamental question is being raised as to whether these are still the right tools to use in today’s modern Industry 4.0 driven factory, or whether these need to evolve, be enhanced, or even replaced in order to meet the more extreme requirements of operational flexibility, as well as cope with volatile material availability in the market.
