Polyurethane Foam Gaskets

Gaskets cut from Polyurethane Foams are one of many products manufactured by Advanced Seals & Gaskets Ltd. Just of these gasket materials is Polyether Polyurethane.  Polyether foam gaskets 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.  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 gaskets can be cut.

Polyether PU foam gaskets are manufactured using drawings or samples provided by our customers, with whom we work closely to ensure the final product is to their exact specification providing samples where needed.  From a simple square picture frame gasket, to a more complete profile with cut-outs, notches or bolt holes - we can offer a solution. Whether it’s a one off sample or a multi-thousand run, we have a machine to quickly and accurately produce perfectly formed recon foam gaskets in a range of sizes, these include various types of presses, CNC and kiss cut machines.  Our Polyurethane foam gaskets can be produced plain or with a choice of finishes including foils, self adhesives or laminated to other materials, depending on the size and quantity of the gasket, they can be supplied as loosely packed parts, or kiss-cut on rolls for quicker and easier application.

    What are Polyether Foam Gaskets?

    Polyether foam gaskets can take the form of strips, pads or intricately cut pieces of material placed between two surfaces to fill gaps and to create a low pressure seal against the intrusion of dust and debris.  Polyurethane foams are 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 gasketing 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.

    Why use Polyether Foam Gaskets?

    Polyether Polyurethane Foam gaskets look very similar to those made using Polyester Foams, but are softer, lightweight and don’t have the rough feeling, sparkly finish. Polyether  have a low density, the materials are manufactured as large blocks of material which can be easily split, sawn and fabricated into many different components each with excellent properties including excellent compressibility,  meaning it will bounce back and recover quickly, this compressibility makes it a great choice of materials of 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 fabrications are perfect for use as cushioning, vibration dampening, heat insulation or surface protection.

    Advantages of using Polyether Polyurethane Foam Gaskets

    Our polyether polyurethane foam gaskets are highly durable and versatile offering a vast range of desirable attributes as well as being cost effective allowing them to be used across several industries and applications. Polyether foams are available in grey or white colour options with  excellent properties.   Being an open cell foam, the Polyether gaskets are  breathable meaning they allow air to circulate throughout its structure, they offer excellent compressibility,  meaning the components 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. The materials soft composition makes Polyether gaskets ideal for use within sportswear, medical devices and more popularly packaging, where many gaskets are used to create air or watertight seals, those made from Polyether are suited for controlling airflow, sound and trapping dust.   Due to the open cell structure of this particular foam, it doesn’t hold moisture, is quick drying and allows some airflow, characteristics which are suitable for outdoor seating, filtration, speaker foams, etc.  Polyether Polyurethane foam gaskets can be found used in a range of sound and vibration dampening applications, cushioning, sealing, impact or bumper pads and even seals or gaskets within aerospace, automotive, machinery and appliances manufacturing.
