Rishorite® ES-3350N (EL-GEF, Rishō Kōgyō)
RISHOLITE
The ES-3350N(EL-GEF) is an insulating material for home appliances and other products where safety is a priority.
Glass epoxy (Galaepo) laminated boards are made by impregnating woven glass fibers with epoxy resin, layering them, and then applying heat curing treatment. They excel in insulation properties, mechanical strength, flame resistance, and low dielectric constant, and are used in a wide range of fields and applications, starting with materials for electronic components, due to their thinness and resistance to warping. The RISHOLITEⓇ (Rishoraito) ES-3350N manufactured by Rishimatsu Industrial Co., Ltd. is a flame-retardant type of glass epoxy laminated board (EL-GEF), with an ANSI standard of FR-4.0 and a UL flame class of 94V-0. It comes in thicknesses ranging from 0.1 to 50 mm and is used as insulation material in home appliances where safety is a priority, such as rice cookers and ovens, with applications including terminal boards and washers. Myojo Electric provides one-stop solutions from material selection and procurement of thermosetting resins, including glass epoxy, and engineering plastics such as thermoplastic resins, to various processing methods including cutting, molding, polishing, bending, and bonding.

Company information
Seiko Electric Co., Ltd. was founded in 1947, shortly after the war. Initially, we only sold insulating materials, but in response to customer requests, we began to offer processing services such as cutting, bending, and laminating. By utilizing our sales and production bases both domestically and internationally, we have been able to provide comprehensive support for our customers' businesses through services ranging from material sales to planning, proposals, processing, and logistics. We continuously challenge ourselves with new technologies in various fields, including smartphones, tablets, display devices, automotive parts, robots, measuring instruments, wearable devices, medical equipment, aerospace, manufacturing equipment, and power electronics, responding to customer needs from material sales to resin processing, tape and film processing, and vacuum lamination processing. Additionally, leveraging our global network for sourcing materials from overseas and supplying materials to overseas factories, we support all phases of "manufacturing," from material procurement to prototyping and mass production, including proposals for transitioning to mass production at our factory in the Philippines after prototyping and small-lot production at our Shirakawa factory.
