    What Is Epoxy Glass Electrical Insulation?

    Epoxy glass is a green coloured composite material made from multiple layers of fibreglass which are then impregnated with epoxy resin creating a strong rigid product in the form of a sheet, rod or tube. Epoxy glass is a transparent, hard and brittle material that offers good mechanical strength and temperature resistance as well as excellent electrical insulation properties, which mean it can be used to restrict the flow of electric current, by supporting electrical conductors - without allowing the current to pass through.

    Why Use Epoxy Glass Electrical Insulation?

    The purpose of using Electrical insulation materials like Epoxy Glass are to provide a barrier to restrict the flow of electrical current, protecting electrical conductors from coming into contact with people or tools during installation, repairs or when an electrical appliance or device is being used.

    Electrical insulation materials also prevent electrical arcing (electrical current flows through the air between two conductors, as a result of the electrical breakdown of gas that produces an ongoing electrical discharge) and are used in other electrical insulation applications. Epoxy Glass Electrical Insulation materials are strong, tough and highly machinable, which can withstand temperatures up to 180°C depending on the grade taken.

    The material is available in a large range of thicknesses from 0.2mm through to 100mm and in rod or tube form, all of which can be machined using a range of drilling, routing and CNC milling processes - very thin sheets can also be converted using presses.

    • Electrically insulating
    • Epoxy glass electrical insulation is available in many grades including chemical resistant and flame resistant
    • Dimensional stability
    • High mechanical strength
    • Epoxy glass electrical insulation is highly machinable

    Types Of Electrical Insulation Materials Available

    Advanced Seals & Gaskets work with a multitude of material manufacturers, giving our customers more choice and ensuring we can offer a solution to just about any application, our most popular electrical insulation materials include:

    Kapton is a polyamide film which offers a combination of mechanical and tear strength along with chemical, electrical and thermal properties that enables the gasket to withstand vibration and extreme temperatures in demanding environments.

    Leatheroid is a grey/blue coloured paper gasket material, also sometimes called Elephantide. This material is used within the electrical industry to insulate hot elements.

    MICA is a mineral based sheeting material which has excellent mechanical performances, is resistant to chemicals and provides electrical and therm insulation. MICA gaskets are often used to replace asbestos as they can withstand extremely high temperatures of up to 1000℃.

    MYLAR is an extremely strong, flexible polyester film. MYLAR is an excellent insulation material with dielectric strength, moisture resistance and is an excellent insulation material.

    Nomex can be manufactured using nomex paper or nomex board, it can withstand high temperatures, has high mechanical and dielectric strength, and is an excellent insulation material for all kinds of electrical equipment and applications.

    Presspahn is a brown coloured material, manufactured using kraft wood pulp. Presspahn sheets have excellent physical and mechanical properties, generally used as electrical insulation.

    SRBF is resin bonded fibre material which is tough and rigid, with an operating temperature of 120℃, low water absorption and is resistant to wear, impact chemicals.

    SRBP (synthetic resin bonded paper) is manufactured using layers of paper and synthetic resins. This material is suited to high and medium voltage application. SRBP has good mechanical and excellent electrical insulation properties, with low water absorption.

    Valox is an excellent electrical insulation material which also offers flame retardant properties.

    PTFE is a non- conductive plastic material used to produce electrical insulation sheets. PTFE sheets are suitable for high temperature applications and have a high melting temperature. This material has excellent dielectric properties and can be often found used in circuit boards.

    PVC is a tough, lightweight abrasion, chemical and moisture resistant material which has good dielectric strength making it a great material to use for electrical insulation applications.

    Advantages Of Using Epoxy Glass Electrical Insulation

    Epoxy Glass Electrical Insulation is one of the most popular resin materials used for electrical applications, acting as an excellent electrical insulator protecting electrical components from short circuiting, dust and moisture.

    As well as electrical applications, Epoxy Glass is often used as an alternative to carbon steel, particularly in pipelines, due to its corrosion resistance, chemical resistance, low thermal conductivity, light weight and desirable mechanical properties.

    Epoxy Glass is available in a number of grades, all a shade of green but each offering its own unique set of properties which can include high chemical resistance, V0 self-extinguishing and flame retardancy properties, high temperature resistance and varying levels of machinability.

    When used as an insulator withIn the electronics industry epoxy glass components such as washers, gaskets, insulation blocks or pads, thermal and heat resistant shields are found used in integrated circuits, transistors and hybrid circuits, making printed circuit boards and as insulators within the heavy transport, mechanical engineering, mining and construction.

    Epoxy Glass Electrical Insulation rods, sheets and tubes can be taken in their raw form, or alternatively, we can convert them into a multitude of bespoke washers, pads, strips and complex gaskets.
