Hydrofera PVA Sponge is a synthetic sponge primarily composed of polyvinyl alcohol foam. It possesses a three-dimensional open cell structure similar to that of a natural sea sponge. All cells are interconnected and not independent. Advantages of this physical structure include high filtering efficiency, extreme softness, and excellent wicking and retention properties. In addition, Hydrofera's Sponge is produced using gas or air as a pore former which yields a stronger and cleaner foam than those foams which use starch or other support pore formers. Hydrofera's proprietary process also allows it to control pore size and structure, wicking rate, surface and core density, and other properties to meet specific customer needs.

Properties and Characteristics

Hydrofera Sponge is highly absorptive and can be made to absorb up to 25 times its weight in water. When hydrated. it becomes flexible and impressively soft while remaining durable and long lasting. PVA sponge exhibits mechanical strength and abrasion resistance properties equal to or greater than any other synthetic or natural sponge material.
