Details and Benefits of PVA Sponges

About PVA Sponge
PVA Sponge, sometimes referred to as Polyvinyl Alcohol (formalized) Sponge, is a high tech plastic sponge that has many of the same properties and qualities of a natural sea sponge. Static-free and lint-free, PVA Sponge is hydrophilic with porosities from 55% to 95%. The surfaces of each sponge can be engineered for specific applications -- from very smooth pores to large open pores like sea sponges. All deliver an exceptionally high volume and speed of absorption, actually holding many times the volume of liquid compared to a natural sea sponge or sheepskin chamois. Elasticity and tensile strength properties help provide durability and allow the material to last much longer than other materials. Some of the unique qualities of PVA Sponge include:

* Rigid when dry, soft when wet
* Very Hydrophilic (it loves water and most liquids)
* Holds up to 12 times its dry weight
* Non-linting, non-scratching
* Mechanically strong, abrasion resistant
* Cells are interconnected
* Non-aging, lasts almost forever
* Natural color is white (may be manufactured in many colors)
* Excellent color fastness (can also be dyed or silk screened)
* Burns without toxic gases
* Good chemical resistance including acids, bases, and organic solvents
* May be molded or shaped in almost any configuration
* Heat resistant to 176oF (80oC) wet, 248oF (120oC) dry
* Pore size variable between 60 to 1500 microns
* Warm or hot water softens PVA sponge faster than cold water
* May be washed by hand or in a washing machine
