Absorbent sponge, PVA absorbent sponge sheet
PVA is a strong absorbent sponge PVA as continuous pores of a porous material body. Porosity and pore diameter control freedom. With the purpose of use, depending on the coloring and processing of arbitrary shape. Select varieties. And excellent wear resistance. Whether industrial use, general living both have a wide range of areas: medical cotton, electronic cleaning cotton. PVA sponge no analogy strengths: continuous pore volume of about 90% by forming pores .PVA sponge, at first glance, like a solid block, but if you look at micro eye, which is 90% of the volume of the hole (pores) in a three-dimensional network structure matrix section. Each air hole is made completely continuous. This one is the most important feature of PVA sponge structure, with many features. Stunning hydrophilic absorbent, water-holding capacity. General methotrexate fat sponge barrier, there is a high hydrophilic and micropores criss capillary action, plays superior absorbent, water retention. A contact with moisture, the adsorption speed, stored in the inside of cotton. (Softness) soft contact will not scratch, moist state softness, flexibility, especially when you do not hurt the surface of the object as the cleaning materials and cleaning materials.
