About sponges:Sponge, a porous material, has good water absorption properties and can be used for cleaning. The sponges commonly used by people are made of wood.Cellulose fiberOrFoamed PlasticPolymer made. In addition, there are natural sponges made from sponge animals, most of which are used for body cleaning or painting. In addition, there are three types of synthetic sponges made from other materials, respectively low densitypolyetherNon-absorbent sponge聚乙烯醇（Highly absorbent material, no obvious pores）Polyester。

Production ProcessFoamed resin,foaming agentandAdhesiveResin (to make the finished product adhesive) is mixed together; foam processing is performed. Mix 80 parts of EVA, 20 parts of APAO PT 3385, 20 parts of azodicarbonamide, 19 parts of CaCO3, and 0.6 parts of dicumyl peroxide together, place it in a mold for foam formation, and break closed pores with mechanical force, thereby producing foam sponge. Its density (d) is 0.028 g/cm3, and 25% of it is Compression HardnessFor 1.9 KPa.
