Open Cell sponge
High washability and exceptional durability
Open cell sponge is mainly a consecutive pneumatophore made from natural rubber. It differs from other rubber sponge (closed cell pneumatophore) in its dual aspect of water absorptivity with a unique surface roughness that gives the materials its strong washing properties. Since it does not have closed cells, the sponge has superior restorativity and is used in repeated compression and high compression applications.
■ Main applications: ： Cushioning material, filter medium, pipe-washing sponges, and washing of engineering products
