Electrolube Launches First Clear UL94 V-0 Flame Retardant PU Resin for any LED Market

The global electro-chemicals manufacturer, Electrolube, has frequently been approached about the prospect connected with an optically clear, flame retardant resin. As being the requirement for LED encapsulation ever increases, specifically hazardous areas, Electrolube is promoting the long-awaited new UR5641 encapsulation resin.

Technically, UR5641 almost defies convention and is particularly quite different from other resins claiming to generally be flame retardant and transparent. Traditionally, as a way to purchase the desired flame retardancy resin manufacturers have tried solid fillers to accomplish flame retardancy but such fillers function not permit a transparent resin when cured. ?Traditional liquid flame retardants are typically halogenated, whereas Electrolube’s UR5641 isn’t going to contain any fillers and has now the extra selling point of being halogen free.

Conventional resins claiming being flame retardant and optically clear actually are a pale amber when cured. Several of these resins tend to remain based on epoxy technology that can be vulnerable to yellowing. Electrolube’s UR5641 is based upon aliphatic urethane chemistry, that is certainly naturally resistant to the yellowing negative effects of day light, which makes it useful for both exterior and even interior applications.

UR5641 cures to supply a flexible, protective and aesthetically pleasing covering in the luminaire elements. The resin also provides high ability to resist weather, acids and alkalis, water and mould growth. UR5641 may be a two-part, semi-rigid, optically clear, flame retardant polyurethane resin to suit the UL94 V-0 standard. Caused by a carefully selected combination components, UR5641 is a really durable, low viscosity system you can use for that wide variety of applications. The fresh resin is eminently well suited for the security of LED luminaires come across hazardous atmospheres, for example emergency lighting, or lighting for the purpose of installation in ATEX rated/zoned environments.

The UR5641 resin demonstrates high dielectric strength at 11 kV/mm, excellent thermal conductivity of 0.35 W/m.K and give a large operating temperature cover anything from -40 to +120 C. The RoHS-2 compliant resin in addition has a cure time within Round the clock at 23C or 4 hours at 60C.

Ron Jakeman, Electrolube’s Managing Director, comments, “We are already frequently asked over many years with regards to a fully clear, flame retardant resin system, and saw an opportunity to give you a solution for that LED market, where our track record of providing high quality, reliable chemistry solutions is growing considerably. Electrolube is quickly the go-to resource for specialist technical solutions that solve customers’ manufacturing problems and make them bring high-quality products to showcase faster.?The UR5641 is actually a world-first product, genuinely offering a completely transparent, UL94 V-0 flame retardant answer to the LED market. Now we have launched the merchandise globally and tend to be very serious about the feedback we are receiving from customers currently testing the resin.”
