Kapton Electrical Insulation Pads

Kapton Pads

ASG’s on-site conversion facilities are market leaders in the production and supply not only of sponge and rubber pads, but also a multitude of specialist fibre, resin, plastic and paper based materials and products designed for specific applications such as electrical insulation (used to manufacture products such as (kapton electrical insulation pads).

One such material used to electrically insulate is Kapton - a polyimide film excellent for use in electrical insulation applications with outstanding thermal, mechanical, chemical and electrical properties. Kapton film raw materials are manufactured in roll form, in thicknesses from 23 to 125 micron, which can be laminated with an adhesive coating prior to being converted or cut into kapton electrical insulation pads.

All of our Kapton pads are produced on-site using drawings or measurements provided by our customers, to ensure the final product is to their exact specification. Depending upon the size and quantity required we have a machine to efficiently cut the pads in the most timely and cost effective manner - with the option of having them supplied loosey packed or kiss-cut and supplied in roll form.

    What Are Kapton Electrical Insulation Pads?

    Kapton pads are cut from master rolls of material, often for use in a similar way to a gasket whereby they fill gaps and provide electrical insulation within electrical applications and appliances, as we manufacture and convert on-site, our customer have the option of takings their pads as squares or rectangles with the option of radius corners, or as circular or oval shaped pads or ‘discs’.

    These electrical insulation pads are cut from Kapton which is a polyamide film, also know in the industry by the chemical name ‘poly 4,4'-oxydiphenylene-pyromellitimide’ - this film is produced using (PMDA) pyromellitic dianhydride and 4,4’ oxydiphenylamine (ODA), creating the Amber coloured film used in many extreme temperature electrical insulation applications on items such as circuit boards, transformers, motors and fiber optics to restrict the flow of electric current, by supporting electrical conductors - without allowing the current to pass through.

    Why Use Kapton Electrical Insulation Pads?

    Electrical insulation products, including pads made using Kapton film serve the purpose, as the name suggests of insulating! Kapton film pads provide a barrier restricting the flow of electrical current, protecting electrical conductors from coming into contact with people or tools during installation, maintenance and when an electrical appliance or device is being used.

    Kapton Electrical insulation pads 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).

    Alongside the excellent electrical insulation properties, Kapton also demonstrates temperature stability, flame and chemical resistance and mechanical strength. This high quality material with its unique property combination makes for the perfect material to cut pads for use within aircraft and aerospace applications. Kapton film is manufactured in various grades and thicknesses between 23 to 125 micron which can be supplied in full rolls, sheets or pre-cut pads.

    Benefits Of Using Kapton Electrical Insulation Pads

    • Temperature stability between 269 °C to 400 °C
    • Electrically insulating
    • kapton pads offer resistance to chemicals such as organic solvents and strong acids
    • UL-94 V0 classified - high flame resistance and self-extinguishing
    • Kapton electrical insulation pads are Abrasion, tear and puncture resistance
      UV and Gamma radiation resistant

    Other Types of Electrical Insulation Gasket Materials Available

    Advanced Seals & Gaskets work with a multitude of material manufacturers and suppliers, giving our customers more choice of electrical insulation materials- some of the most popular being:

    Epoxy Glass - A green-coloured material with good mechanical strength, good chemical, electrical and radiation resistance, low moisture absorption and a working temperature range of up to +120℃.

    Valox - Valox electrical insulation offers dielectric strength, electrical properties, an operating temperature range of -40°C to 130°C and resistance to a wide variety of chemicals including hydrocarbons, dilute acids and bases, detergents and aqueous salt solutions. Valox materials like other plastics offer high-strength and impact resistance, good flexibility, and resistance to shrinkage.

    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, and 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 applications. SRBP has good mechanical and excellent electrical insulation properties, with low water absorption.

    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 often be 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 Kapton Electrical Insulation Pads

    Kapton film pads offer a number of desirable properties, exhibiting outstanding performance making is a popular choice for the production of high quality pads. Kapton electrical insulation pads are often found used within aircraft, aerospace, rail and automotive applications, where properties such as mechanical strength (resistance to abrasion, tear and puncture), high dielectric strength, chemical resistance and fire resistance are crucial.

    Kapton electrical insulation pads are highly durable, capable of maintaining it’s mechanical properties whilst withstanding vibration and extreme temperatures ranging from -269°C through to +400°C. Katon raw materials are manufactured in a number of grades and thicknesses with varying levels of resistance, each of which can be supplied as master rolls, cut sheet or pressed into pads.
