PVA sponge sponge absorbing stick industrial water pipe PVA sponge PVA sponge absorbing a roller is the raw material for continuous polyvinyl alcohol (PVA) of geologic stomatal porous. Gas aperture, porosity ratio control freedom. Along with the purpose and decide, the colour and shape on the processing can be arbitrary choice varieties. And good wear resistance. No matter use, the industry which is general life widely. PVA sponge from the analogy of the special skill: continuous porosity, about 90% of the volume of gas hole formation. PVA sponge, at first glance, like a solid block, but if use the eye to see, the volume of the 90% of hole (porosity) execution of matrix is stereo mesh structure. Each stomatal all continuous and into. This one structure is the biggest characteristic of PVA sponge, it has many functions. (hydrophilic) amazing ability of absorbing water and preserving PVA sponge and genera
