PTFE Plastic Pads

Cut and pressed pads make up just a small proportion of the thousands of products manufactured and supplied from 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 plastic pads, 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 Plastic Pads?

Pads made using PTFE plastic strips are cut from full sheets of material. 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.  PTFE fluorocarbons remain solid at room temperature, hydrophobic and non-stick. PTFE pads which are made using a ‘Virgin grade’ in comparison to other plastics have a low mechanical strength, however this can be improved or reinforced with the inclusion of additives such as glass fibre or carbon during the raw material manufacturing process.

When choosing pads, our customers have the option of taking PTFE plastic 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 and even laminate multiple types of material together to create bespoke and unique variations

Why Use PTFE Plastic Pads?

When plastic 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 plastic pads are soft and formable, with good bearing and wear properties, and high dielectric strength.

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

Advantages Of Using PTFE Plastic Pads

Pads cut from PTFE or Polytetrafluoroethylene offer 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 plastic 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 plastic 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 seals and 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.
