Polyester Polyurethane Foam Rolls
Polyester Polyurethane Foam Rolls
Advanced Seals & Gaskets Ltd supply rolls of Polyester Polyurethane which are available in a selection of grade and densities. Polyester Polyurethane foams are also referred to as Polyester Urethane Foam, Ester Based Polyurethane Foam and Esterfoam. Polyester PU foam materials are flexible, exhibit high tensile strength and chemical resistance, in comparison to Polyether foam, these rolls of foam 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 rolls are not only manufactured using a standard grade of material, but can also be manufactured to order in anti-static, conductive electrostatic dissipative (ESD) and Flame Retardant (FR).
Ester foam rolls can be cut down for use in packaging applications, however because of its rough gritty surface texture and chemical instability, an additional material is often required between the foam and the object being packaged to protect it. 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 into 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 in bespoke sizes, but we can also apply a choice of self adhesives or foils.

What are Polyester Polyurethane Foam Rolls?
Polyester Polyurethane foam is manufactured in master blocks around 2 to 2.5meters in length, 1 to 2 metres in width and 175 to 1260 mm in thickness, these blocks are glued and butted together using heat. These joined blocks are then fed through one of our state of the art splitters, which work by setting the blade to peel off the desired thickness of foam which is then hand rolled by the operator around core until the full length of material is done. Like Polyether, Polyester Polyurethane Foam is another member of the polymer family, also known 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 rolls to be able to meet various fire code standards, as well as anti-microbial, anti-static, conductive and/or electrostatic dissipative (ESD).
Why Use Polyester PU Foam Rolls?
Polyester Polyurethane rolls of material look very similar to those made using Polyether foams, but are often selected for applications which require a higher level of chemical resistance. Polyester Foam rolls are more resistant to hydrocarbons, alcohols, stretching and tearing, they 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. Components cut from Polyester PU Rolls include strips, washers, gaskets and pads, which can be used in applications to fill gaps and irregularities between uneven surfaces, provide a solution to unwanted rattles, noise, vibrations, to seal against dust and can also be used to cushion between moving parts to reduce friction and damage to components and equipment, filtration, protective packaging and medical equipment.

Advantages of using Polyester Polyurethane Foam Rolls
Polyester foam rolls 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, these Polyester rolls are breathable, meaning they allow air to circulate throughout its structure. Polyester rolls offer excellent compressibility, which enables them to bounce back and recover quickly from repeated loading, this makes it a great choice of materials for cushioning applications. Polyester foam is flexible with a high tensile properties and tear resistance, resistance to mould, mildew and fungus growth as well as grease oil water and can be used within a working temperature range of around -30°C to +110°C.
Polyester PU foam rolls can be used in applications where there is contact or exposure to gases 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, known as Pink Anti=static foam, rolls made using this pink foam dissipates electro-static charges in sensitive electronic equipment or instruments. Because of Polyester PU foams greater rigidity, rolls of material can be used in the production of cleaning products like sponges and mops, some of the other ways in which Polyester Polyurethane foam rolls can be found used include acoustic tiles and soundproofing pads, as protective packaging case inserts and as water or air filters.
