Merocel Banner - What is Merocel

What Is Merocel® Material?

Merocel PVA is a highly advanced biocompatible synthetic material. It's produced by a chemical reaction resulting in cross-linked polyvinyl alcohol with a completely open cell structure. The final PVA sponge material has 100% open pores in its structure with no "dead-end pockets" to hold residues.

What Is Merocel® Material?

This structure, along with the sponge's unique reticulated form, makes it both absorbent and hydrophilic. The Merocel material is exceptionally strong and durable, yet soft and comfortable when hydrated.
