Larger cellulose sponges are easily cut into smaller pieces for smaller or specialized jobs.
How are Duro-Cel Brand Cellulose Sponge Made?
Cellulose sponges are typically made from a mixture of wood pulp (cellulose), sodium sulphate crystals, fibers and softeners (materials, such as flax, are often added to provide additional strength or chemical resistance). The process of manufacturing cellulose sponges begins with large stiff sheets of cellulose that are then soaked in a vat of water and mixed with softeners. Once the sheets have been softened and become “jelly-like”, they are moved to a revolving mixer where sodium sulphate crystals and dye are added. After the ingredients have been thoroughly mixed, they are poured into a mold and heated.
As the mixture is “cooked”, the sodium sulphate crystals melt and drain out through the bottom of the mold. The voids left behind by the the crystals create the pores in the finished sponge. The size of the crystals determine the size of the pores.
Cellulose sponges with larger pores, such as those used for washing a car or truck, are made with larger crystals. Finer pore sponges, such as those used for applying makeup, are made with much finer crystals. The cellulose mixture hardens into a porous block as it cools and is finally cleaned and colored before being dried and cut into the appropriate sizes for packaging.
