Kapton Gasket
Kapton Gasket
Advanced Seals & Gaskets Ltd are market leaders in the production and supply of sponge and rubber products, however also renowned for the number of specialist fibre, resin, plastic and paper-based materials and products designed for specific applications such as electrical insulation (such as Kapton Electrical Insulation Gaskets).
One of our electrical insulation gasket materials is Kapton, which is a polyimide film excellent for use in electrical insulation applications with outstanding thermal, mechanical, chemical and electrical properties. Kapton film is manufactured in roll form and in thicknesses from 23 to 125 micron, which can be laminated with an adhesive coating prior to being converted or cut into gaskets.
The quality of the cut is a major factor in producing a reliable and perfectly fitting gasket, therefore we ensure our in-house manufacturing team follow our customers drawings or samples in order to create an exact match - from a simple square picture frame gasket or a more complex shape with cut-outs - we can offer a solution, creating one off samples or multi-thousand batch runs, we have a machine to quickly and accurately produce perfectly formed gaskets in a range of sizes, these include a number of presses and CNC machines.

What Are Kapton Electrical Insulation Gaskets?
Electrical Insulation Gaskets serve the purpose of insulating components within electrical applications and appliances. These gaskets can take the form of a strip, pad or bespoke shapes cut from certain materials, in this case Kapton.
This electrical insulation is a polyamide film, which also goes by its chemical name ‘poly 4,4'-oxydiphenylene-pyromellitimide’ - this film is produced using (PMDA) pyromellitic dianhydride and 4,4’ oxydiphenylamine (ODA). This chemical formulation produces 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 Gaskets?
Electrical insulation gaskets, including those made using Kapton film, provide a barrier restricting 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.
Kapton Electrical insulation gaskets 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 also used in other electrical insulation applications.
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. 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 finished usable gaskets.
Benefits Of Using Kapton Electrical Insulation Gaskets
- Temperature stability between 269 °C to 400 °C
- Electrically insulating
- Resistance to chemicals such as organic solvents and strong acids
- UL-94 V0 classified - high flame resistance and self-extinguishing
- 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 gasket 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.
Advantages of Using Acoustic Foam Gaskets
Acoustic foam gaskets hold various advantageous properties that are highly utilizable in a variety of industries.
The greatest advantage of using acoustic foam gaskets is the exceptional noise dampening capabilities of the material. As acoustic foam is an open cell material it is highly effective at absorbing sounds as well as cushioning and padding.
Acoustic foam gaskets commonly used as the material performs multiple functions at the same time, while the acoustic foam gasket is applied for cushioning the material will also absorb sound waves dampening the noise.
