Cellulose Sponge

Product Name

Cellulose Sponge

Outline

Our Cellulose Sponge is made from natural pulp as the principal ingredient. It is toxic-gas free when burned and biodegradable when buried.

Wth these earth-friendly properties and our unique technologies, we are developing diversified applications for cellulose sponges with the goal of better environmental protection.

Features

■100% natural material
Cellulose sponge is made from cellulose that is originated from pulp and natural fiber such as cotton as a reinforcement, both of which are environment-friendly, 100% natural recyclable vegetable fiber. No carbon dioxide is generated on disposal as it contains no petroleum ingredient.

■Easy absorption of water
Cellulose absorbs water easily as a hydrophilic group (OH group).

■High porosity
The gravity is very light as about 0.04 g/CC in dry condition, and it consists not less than 95% of air bubbles in its volume.

Application

■Medical: Adhesive plaster, Disinfection items, Medical treatment pads for low-frequency therapy equipment, Ophthalmic surgery.

■Printing: Wipers for offset printing plates.

■General use: Household wiping material, Car washing, Mops.
