With over 70 years’ experience in adapting and designing Ramerfoam®.
PVA Foam Sponge Technology to meet the needs of engineers and designers worldwide.
PVA sponge is a synthetic sponge essentially composed of Polyvinyl Alcohol. Its an open-celled highly absorbent porous material that wicks aqueous solutions quickly. It is compressible when dry, 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 hydrated sponge can withstand temperatures approaching 70°C and about 100°C when dry.
The communicating cell structure of PVA sponge is ideal for any application where absorbency, durability and versatility are key.
PVA sponge is inert after sterilisation. For storage purposes wet packed sponge can be treated with a biocide solution to inhibit mould and bacterial growth.
PVA sponge requires different handling and processing techniques compared to other more widely used sponge materials. With over 70 years, experience Ramer Ltd has the unique technical expertise to assist customers with product design and development.
Ramer has manufactured Ramerfoam® since 1949 and was the first company to create and market a commercially viable synthetic sponge in the UK. It is produced by a tried and tested manufacturing process which enables us to offer a bespoke service. Ramerfoam® can be supplied in a wide range of colours, shapes and cell sizes. All our products are produced in the UK at our factory in Devon.
