Polyester Foam Pads
One type of polyurethane foam pads supplied by Advanced Seals & Gaskets Ltd are those made using Polyester Polyurethane, also referred to as Polyester Urethane Foam Pads, Ester Based Polyurethane Foam Pads and Esterfoam Pads. These PU pads are made using Polyester which is a flexible foam that exhibits high tensile strength and chemical resistance. In comparison to Polyether foam, these pads are generally more rigid, stronger, and supportive, with physical differences including a glittery sparkle in appearance and feel rougher and more dense to the touch.
Ester foam pads are not only cut from standard grade Polyester Foam, but can also be manufactured to order in anti-static, conductive electrostatic dissipative (ESD) and Flame Retardant (FR). Polyester Polyurethane foam is manufactured in very large master blocks or ‘buns’ usually ranging from around 2 to 2.5meters in length, , 1 to 2 metres in width and 175 to 1260 mm in thickness, which are held in stock from which pads can be cut. Polyester foam pads are produced on-site using drawings or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification.
Depending upon the size and quantity of pads required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one off samples to multiple thousand batch runs, which can be supplied as loosely cut parts, or kiss-cut on rolls - where a high quantity is required or for use on fast paced assembly lines. Our Polyester foam pads can be supplied in a plain finish, laminated in layers to create greater thicknesses, laminated to other materials or coated with a choice of self-adhesives and foils prior to the pads being cut.

What are Polyester Foam Pads?
Polyester foam pads are often taken to be used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities, provide cushioning or dampen noise and vibration. Our Polyester PU foam pads can be 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 from as little as around 1.5mm. 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. Polyester Polyurethane Foam is a member of the polymer family, it is also known as Polyester Foam or Ester Foam, a flexible material which produces pads with a high tensile strength and chemical resistance, offering a greater strength and rigidity in comparison to Polyether. Polyester Polyurethane is manufactured in a charcoal colour as standard, formulated and manufactured using a combination of polyester polyols, catalysts and blowing agents which create the foam open cell texture. During the manufacturing process, additives can be introduced which will enable the Polyester Foam pads to meet various fire code standards, as well as anti-microbial, anti-static, conductive and/or electrostatic dissipative (ESD).
Why Use Polyester PU Foam Pads?
Polyester Polyurethane foam pads look very similar to those cut from Polyether foams, but are often selected for applications which require a higher level of chemical resistance. Polyester Foam pads are more resistant to hydrocarbons, alcohols, stretching and tearing, they have a fine open cell structure which is uniform in appearance and permeable to air and water, whilst giving it a higher viscosity rate, abrasion and cut resistance.
Polyester PU foam pads have a fairly high tensile strength, but not as high as standard polyethylene foams, and can be used in environments which have a temperature range of around -30 to +110 ºC. Polyester Foams pads can be cut into bespoke sizes where they are used in applications such as filtration, sound and vibration absorption, protective packaging and medical equipment.

Advantages of using Polyester Polyurethane Foam Pads
Polyester foams and the pads cut from them are highly durable and offer a range of attractive properties and characteristics for use in many applications. Just a few of these features include the pads' open cell structure, the Polyester is a breathable material meaning its allows air to circulate throughout its structure. Polyester Pads offer excellent compressibility, meaning they will bounce back and recover quickly from repeated loading, making them a great choice of materials for cushioning applications. The Polyester and components including pads cut from them are flexible with a high tensile properties and tear resistance, resistance to mould, mildew and fungus growth as well as grease oil water and temperature with working temperature range of around -30°C to +110°C.
Polyester PU foam pads can be used in applications where there is contact or exposure to gasses including oxygen, nitrogen and carbon dioxide whilst its fine cell structure gives the material less flex resulting in a better shock absorbing product. During the raw material production Polyester Foam compounds can be treated with agents which produce a pink coloured polyester, also known as Pink Anti-static foam, which is another grade we can use for cuttng pads.
This Pink Anti-static foam dissipates electro-static charges in sensitive electronic equipment or instruments. Because of Polyester PU foams greater rigidity, they can be made into cleaning products like sponges and mop heads, some of the other ways in which Polyester Polyurethane pads can be found used include acoustic tiles and soundproofing pads, as protective packaging case inserts and as water or air filters.
