PVA sponge is a synthetic sponge essentially composed of Polyvinyl Alcohol. It is an open-celled, highly absorbent porous material that wicks aqueous solutions quickly. It is compressible when dry, expandable when wet, has high tensile strength, good elongation and excellent resistance to most chemicals.
PVA sponge is hydrophilic and can hold up to 12 times its dry weight in water. Cell size can be varied depending on the required use; the finer the cell the better the capillary action. The wet sponge can withstand temperatures approaching 70°C and the dry about 100°C.
PVA sponge is effectively inert and will not, in itself, support microbial growth. Wet packed sponge can be treated chemically to inhibit mould and bacterial growth.
Our PVA sponge – made from Ramerfoam® – has been manufactured in the UK exclusively by Ramer Ltd since 1946. We were the first company to create and market a commercially viable synthetic sponge.
The interlinked cell structure of Ramerfoam® is perfect for any application where absorbency, durability and versatility are key.
PVA requires different handling and processing than other more widely used foams. As we have been manufacturing Ramerfoam® for over 70 years we have an unmatched technical expertise to assist our customers in product development.
Ramerfoam® can be supplied in a wide range of colours, shapes and pore sizes. Ramer® PVA sponge is the product of a tried and tested manufacturing process which means we are able to offer a bespoke service. All Ramerfoam® products are produced at our Devon factory in the UK.
