Polyester Polyurethane Foam
Polyester Polyurethane Foam
One of the polyurethane foams supplied by Advanced Seals & Gaskets Ltd is Polyester Polyurethane which is available in a selection of colours, grade and densities. Polyester Polyurethane foams are also referred to as Polyester Urethane Foam, Ester Based Polyurethane Foam and Esterfoam.
Polyester PU foams are a flexible foam that exhibits high tensile strength and chemical resistance, in comparison to Polyether foam, it is 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 foams are not only manufactured in a standard grade, but can also be manufactured to order in anti-static, conductive electrostatic dissipative (ESD) and Flame Retardant (FR).
Ester foams can be used for packaging applications, however because of its rough gritty surface texture and chemical instability, an additional material if often required between the foam and the object being packaged. 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 we can convert sheets and rolls at various thicknesses starting from as little as 1.5mm.
As we offer in-house conversion and lamination services, we can not only split Polyester materials down, we can also glue layers together to create very thick products or laminates using multiple materials and apply self adhesives or foil facings. Our onsite facilities consists of a number of presses, log cutters, strippers, bandsaws and CNC machines from which we can produce a number of Polyester Foam components including gaskets, washers, strips, pads and fabrications.

What is Polyester Polyurethane Foam?
Like Polyether, Polyester Polyurethane Foam is another member of the polymer family. Polyester Polyurethane is also knows as Polyester Foam or Ester Foam, a flexible material which has 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 to meet various fire code standards, as well as anti-microbial, anti-static, conductive and/or electrostatic dissipative (ESD).
Why Use Polyester PU Foam?
Polyester Polyurethane foams look very similar to Polyether foams, but are often selected for applications which require a higher level of chemical resistance. Polyester Foams are more resistance to hydrocarbons, alcohols, stretching and tearing.
Polyester Foams have a fine open cell structure which is uniform in appearance is permeable to air and water, whilst giving it a higher viscosity rate, abrasion and cut resistance.
Polyester PU foams have a fairly high tensile strength, but not as high as standard polyethylene foams, and have a temperature resistance of -30 to +110 ºC. Polyester Foams can be cut into a number of components such as gaskets, washers, strips and pads for use in many applications such as filtration, sound and vibration absorption, protective packaging and medical equipment.
Available grades of Polyurethane
Advanced Seals & Gaskets Ltd work with a number of material manufacturers, giving our customers more choice when looking for polyurethane foams , our most popular grades being:
- Egg box
- Pick & Pluck
Benefits of using Polyester Polyurethane Foam
- Cushioning & Insulation
- Low thermal conductivity
- Low water vapor transmission
- Sound absorption/Vibration dampening
Advantages of using Polyester Polyurethane Foam
Like Polyether Foams, Polyester foams and products cut from them are highly durable and offer a range of attractive properties for use in many applications. Being an open cell foam, the Polyester is a breathable material meaning its allows air to circulate throughout its structure. It offer excellent compressibility, meaning it will bounce back and recover quickly from repeated loading, this compressibility makes it a great choice of materials for cushioning applications.
It’s 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 foams can be used in applications where there is contact and exposure to gasses including oxygen, nitrogen and carbon dioxide, its fine cell structure gives the material less flex resulting in a better shock absorbing material.
Polyester Foams can be treated with agents which produce a pink coloured polyester, also known as Pink Anti=static foam, this 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 mops, some of the other ways in which Polyester Polyurethanes can be found used include acoustic tiles and soundproofing pads, as protective packaging case inserts and as water or air filters.
