Industrial Sponge Washers

Here at Advanced Seals & Gaskets Ltd, we pride ourselves on being one of the UK’s largest manufacturers and suppliers of non-metallic washers, offering a range of specialist sponge materials including open cell industrial sponges (also called Sorbo sponge or open cell natural industrial sponge). The open-cell industrial sponge is manufactured in rolls of various lengths in standard thicknesses ranging from 3mm up to 25mm with skin finish on both faces from which washers can be cut.   

All our washers are manufactured in-house using a combination of a skilled workforce and high-spec machinery, using either our oscillating knife or one of our many presses, depending upon size, thickness and quantity required.  Our range of machinery means we can manufacture Industrial Sponge washers to match your specified dimensions in any quantity quickly and efficiently, which in return passes on a quality product and a cost-saving.

Industrial sponge or Sorbo sponge washers are produced using either samples, drawings or dimensions provided by customers, which would detail the outer diameter (OD), internal diameter (ID) and the thickness, manufactured in a plain, self-adhesive or foil-faced finish, as singular cut parts or kiss cut on a roll.

What are Industrial Sponge Washers?

The open-cell industrial sponge is a natural rubber sponge material manufactured with patterned skin and an open-cell structure giving it excellent compression recovery properties and allows for the circulation of gases and fluids in applications that require it. 

Open-cell Industrial sponge can be used to produce washers, ‘washer’ is a flat piece of material that is placed between two surfaces or between joints in order to reduce friction and prevent unsteadiness, creating a level surface for nuts, bolts and other fixings to rest on, improving the fit for fixings and can be used as a water or airtight seal.

    Why use Industrial Sponge Washers?

    Open-cell natural sponge rubber is manufactured to be soft and compressible, with excellent compression recovery properties.   Open-cell natural industrial sponge rubber is pre-manufactured and stocked in a range of standard roll lengths and thicknesses, ready for despatch or conversion into usable cut parts including washers.  

    Using Open cell natural industrial sponge rubber offers good anti-vibration and acoustic absorption, resistance to weathering and ozone and can be used for the seal between uneven surfaces, as protective packaging and as noise reduction.

    The Advantages of using Industrial Sponge Washers

    There are many advantages to using industrial sponge washers within many applications.  The industrial sponge is soft- feel material with an open-cell structure allowing the material to be used in applications where resistance to fluids is only required when a surface coating is applied, otherwise, it will still allow for liquid absorption, allowing for the circulation of moisture and gas when the application requires it. 

    Open-cell natural sponge rubber washers are available in a range of thicknesses, all offering excellent compression recovery particularly when it’s used for repetitive loading and distortion applications such as packaging and expansion joint sealing, it also has excellent sound and vibration absorption properties making it perfect for use in flooring systems and within machinery.

    Benefits of using Industrial Sponge

    • excellent compression recovery properties.
    • seal around uneven or complex shapes
    • interconnected cell structures also allow for the limited absorption 
    • circulation of gases and fluids
    • Good anti-vibration properties
    • Good weathering & ozone resistance

    Other Grades of Sponge Materials Available

    • EPDM - medium, firm, semi-open cell, high temperature 
    • Neoprene - FR, medium, firm
    • Silicone
    • Polyurethane
