Foam Seals

Advanced Seals manufacture and supply an array of seals, manufactured using one of over a hundred material types.  A group of materials from our catalogue are Polyurethane Foam Seals, available in different open cell variants in various grades, densities and colours, one of which is Polyether Polyurethane. 

As with other PU foams, Polyether foams are suited to a wide range of applications as it’s a highly versatile material offering more resistance to oxidation and ageing in comparison to most other rubber and foams.  As well as being durable and lightweight, it is also cost-efficient making it a popular choice for many items classed as ‘long-life’ such as seat cushions and sofa fillings. 

Polyether 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 seals can be converted.   

Our Polyether foam seals are available in the form of gaskets, washers, strips and fabricated parts, which are all designed for the purpose of filling gaps and restricting air and liquid flow, as well as the ingress of dust and debris.  Working with our customers during the design and material selection process is important as it enables us to produce seals to match their exact required specifications, ensuring the seal doesn't fail once it is placed within the application. 

By using our customers' drawings or samples, we are able to produce Polyether Foam Seals in many forms whether it's a simple washer to a more complex fabricated profile which can be laminated and carved into the finished product - we can offer a solution. From small sample batches to a multi-thousand off run, we have a machine suited to quickly and accurately produce perfectly formed Polyether seals in a range of shapes and sizes, supplied plain or with a choice of finishes including a selection of foils and self adhesives.

    What are Polyether Foam Seals?

    Polyether Foam Seals can be manufactured in many forms using blocks, rolls or sheets of Polyether material.  Polyether is a Polyurethane foam,  just one of many members of the polymer family, with Polyether being a soft, open cell, low density variant, available in grey or white often used in low cost applications.

    Polyether PU foams are formulated and manufactured using a combination of polyether polyols, catalysts and blowing agents which create the foam open cell texture.  During the manufacturing process, further additives can be added to the formulation in order to produce Polyether foam with additional properties such as flame retardancy, anti-static, anti-bacterial and many more. 

    A  Polyether Foam Seal is a term used to describe products often taking the form of cut gaskets, strips, washers, extruded trims and fabricated profiles often used as a gap filler between surfaces, acting  as a separator or a barrier to control the flow of liquids, air and dust penetrating the application and also found in a number of vibration dampening and insulating applications.

    Why use Polyether Foam Seals?

    Seals produced using Polyether Polyurethane Foams are soft, lightweight and have a low density, the raw  materials are manufactured as large blocks of material which can be easily split, sawn and fabricated into many different shaped and sized seals.  

    Prior to cutting into seals, Polyether foam seals can be laminated with a choice of foils and self-adhesives applied to one or both faces, for very thick seals or where a combination of properties are required, the foam can be laminated together in layers or can be laminated to other materials for use within more specialist applications when composite materials are needed.  

    Polyether Foam components, including seals have a number of excellent properties including excellent compressibility,  meaning it will bounce back and recover quickly, 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 -20°C to +120°C.   Polyether Polyurethane is perfect for use as seals, cushioning, vibration dampening, heat insulation or surface protection.

    Alternative 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:

    Advantages of using Polyether Polyurethane Foam Seals

    Our polyether polyurethane foam seals are high quality, are highly durable and versatile offering a vast range of desirable attributes as well as being cost effective allowing it to be used across several industries and applications.

    These foam seals are available in grey or white colour options with  excellent properties.   Being an open cell foam, the Polyether is a breathable material meaning it allows air to circulate throughout its structure. 

    It offers 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 -20°C to +120°C.  

    Its soft composition makes it ideal for use within sportswear, medical devices and more popularly packaging.  Due to the open cell structure of this particular foam, seals cut from it will not seals against air, gas or water leakage, they will not hold moisture, are quick drying and allow some airflow, characteristics which are suitable for outdoor uses, filtration, speaker foams, etc. 

    Polyether Polyurethane foam seals can also be found used in a range of sound and vibration dampening applications and even seals or gaskets within aerospace, automotive, machinery and appliances manufacturing.
