The PVA sponge is pure white, clean, uniform, comfortable and highly flexible, which can be widely used for PVA expansive hemostatic sponge, Liquid absorbing sponge PVA sponge, Negative Pressure Wound Therapy PVA sponge. The production process is applied by clean gas foaming process and phase separation technology, therefore the PVA sponge shows round and porous bubble shape in microscope by SEM(scanning electron microscope), and the pore wall shows obvious "bubble" characteristics, which is essentially different from the sponge produced by starch filling process. Performances of product such as pore size, density, flexibility and tensile strength could be well controlled.

400 Micron Scanning Electron Microscope Picture Benefits

1.No fiber and crumbs will drop during surgery, no reinfection.
2.Soft, comfortable & painless.
3.Instantly liquid absorption ability and the absorption is 10-18 times its weight.
4.Stops nose bleeding fast, absorbs wound exudates massively.
5.Moist dressing, no second damage upon removal.
6.Better biocompatibility and no rejection reaction.
7.Highly swelled after absorbing liquid, form micro-negative pressure which is beneficial to wound healing
