PTFE Electrical Insulation Pads
PTFE Electrical Insulation Pads
Cut or pressed PTFE electrical insulation pads make up just a small percentage of the thousands of products manufactured and supplied by Advanced Seals & Gaskets Ltd.
We are able to offer pads produced using numerous grades, colours and thicknesses, one of which includes a variety of plastics, including PTFE electrical insulation, sourced from a network of plastic material manufacturers and suppliers. PTFE plastics or ‘Polytetrafluoroethylene’, sometimes also referred to as Teflon is a very versatile material which is manufactured in sheets of between 0.25 and 100mm thick, in sheet sizes of up to 1500mm x 1500mm (depending on thickness) from which pads can be cut.
Using one of our many on-site saws, presses or our oscillating knife, we are able to convert PTFE plastic sheets into bespoke sized pads, which can be supplied plain or coated in a choice of self adhesives or foils.

What Are PTFE Electrical Insulation Pads?
Pads made using PTFE plastic can be used as Electrical Insulators as the materials do not allow electricity to pass through them. PTFE or Polytetrafluoroethylene is a fluorocarbon material - consisting of only carbon and fluorine, natural coloured as standard, however other colours can be made to order.
When choosing pads, our customers have the option of taking PTFE electrical insulation pads produced as squares or rectangles with the option of radius corners, and also as circular or oval shaped pads or ‘discs’, in a range of thicknesses. Manufacturing pads in-house even means we can supply them in a plain or self adhesive backed finish which can be placed within electrical applications, where they are used to restrict the flow of electric current, by supporting electrical conductors - without allowing the current to pass through.
Why Use PTFE Electrical Insulation Pads?
When electrical insulation materials are produced, they are all formulated and manufactured using different compounds, allowing us to produce pads with specific properties.
PTFE plastics are manufactured using a unique formulation so that the cut pads can offer many excellent properties and unique characteristics, which include high thermal stability, chemical resistance and an extremely wide operating temperature range of -240 to +260°C. PTFE plastic pads also offer chemical inertness (with the exception of elemental alkali metals, chlorine trifluoride and elemental fluorine at high temperatures and pressures), ozone, flame resistance and an extremely low coefficient of friction meaning few materials stick to it without sufficient preparation.
PTFE electrical insulation pads are soft and formable, with good bearing and wear properties, and high dielectric strength, providing 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.
Benefits Of Using PTFE Plastic
- Excellent temp range -200+260°C (short-term up to 300°C)
- high resistance to many chemicals and solvents
- high dielectric properties
- low friction coefficient (create a slippery surface)
- Non-toxic
- Flame resistance
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 plastic sheeting - our most popular materials 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℃.
- 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.
- 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 PTFE Electrical Insulation Pads
Using electrically insulating Pads cut from PTFE or Polytetrafluoroethylene provide users a number of advantages meaning they are durable and suited for use in many applications and industries. These pads offer low friction, meaning moving parts will easily slide over them, causing less heat and wear, this slippy non-stick material is also easy to keep clean as dirt and dust will not stick to its surface.
PTFE electrical insulation pads are non-flammable, this is due not only to its very low friction, but also its ability to withstand very high heat and its extremely high melting point. PTFE electrical insulation pads offer great chemical resistance, and are extremely resilient when exposed to weathering, combined with the great electrical properties it is ideal for use in most industries.
PTFE plastic sheets are manufactured in a range of standard thicknesses which can be converted into a range of pad sizes as well as other finished components which can be found utilised in a number of industries and applications including fittings in chemical plants, food production and pharmaceuticals. Due to being non-corrosive, these pads can also be used in laboratories where highly corrosive chemicals are handled, and for use within circuit board components due to it’s electrical insulation and heat resistance properties.
Using PTFE Electrical Insulation pads within electrical devices and equipment for the purpose of electrical insulation protects them from generating and passing high voltages, reduces the cost of energy, improves performance and protects users from shock.
