Kapton Rolls
Advanced Seals & Gaskets Ltd are predominantly recognised for their wide range of sponge, foam and rubber rolls of material, however we also stock a convert bespoke and specialist fibre, resin, plastic and paper based materials designed for use within electrical applications.
One of our many electrical insulation materials is Kapton, a polyimide film excellent for use in electrical insulation applications which require outstanding thermal, mechanical, chemical and electrical properties. Kapton films are stocked in roll form and in thicknesses from 23 to 125 micron, and supplied in lengths ranging from 5 meters to 50 meters, however are manufactured in jumbo rolls of up to 914 meters, depending on thickness and at 610mm wide.
These rolls of film can be supplied plain or laminated with an adhesive coating prior to being supplied or converted into finished products.

What are Kapton Electrical Insulation Rolls?
Rolls are continuous lengths of material, in this case Kapton film. Materials are often taken in roll form as they give the customer and end user the flexibility to be able to cut their own components as and when required.
Kapton electrical insulation are rolls of polyamide film, which can also be recognised by its chemical name ‘poly 4,4'-oxydiphenylene-pyromellitimide’ - this film is produced using (PMDA) pyromellitic dianhydride and 4,4’ oxydiphenylamine (ODA), which produces the Amber coloured film found used in many extreme temperature electrical insulation applications on items such as circuit boards, transformers, motors and fiber optics.
Why use Kapton Electrical Insulation Rolls?
Kapton Films are manufactured in roll form in a range of standard thicknesses and lengths, which means they can be dispatched within a minimal lead time as they generally do not need to be joined and split down from blocks.
Kapton films and parts cut from these rolls are used to provide a barrier, restricting the flow of electrical current, protecting electrical conductors from coming into contact with people or tools during installation, maintenance or whilst the device is being used.
Kapton electrical insulation rolls 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).
As well as having 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 use within aircraft and aerospace applications.
Other Types of Electrical Insulation 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 upto +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 a 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, 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.
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.
Benefits of Using Kapton Electrical Insulation

Advantages of Using Kapton Electrical Insulation Rolls
Kapton films offer outstanding performance, demonstrating a number of advantageous properties making it a high quality material with an outstanding performance ideal for some of the most demanding environments.
Parts cut from rolls of Kapton electrical insulation films are often found utilised 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 polyamide films are highly durable, capable of maintaining it’s mechanical properties and withstanding vibration and extreme temperature ranging from -269°C through to +400°C.
Katon Films are manufactured in a number of grades with varying levels of resistance, each of which can further be converted using our state of the art on site facilities where we can produce finished products including pads, gaskets, sheets, strips, tapes and washers in a plain or self-adhesive backed finish.
