Absorbent Foam and Sponge Materials
Reticulated Foams (SIF®) and SIF Felt® can hold many times their weight of various types of liquids and powders in their open cellular structure. The maximum loading capability of these sponge materials results from the absorbent foams' 97 percent void volume. Even a highly compressed SIF Felt® (for example, absorbent foam permanently compressed to 1/10 its final thickness) is still approximately 70 percent void volume. Since these absorbent foams are a three-dimensional structure, they will hold ingredients on the surface as well as within the skeletal structure.
Functions of Absorbent Foam
- Inkjet cartridge wicking materials for ink reservoiring and delivery
- Sponge materials for cleaning surfaces
Absorbent Foam Applications
With over twenty years of experience in this field, we are the world's leading supplier of ink jet cartridge wicking materials. The typical product is a reticulated fine pore, polyurethane absorbent foam that is either felted or compressed during cartridge assembly. The foam functions as a sponge material and reservoir to consistently deliver ink to the print head and stabilize the ink during head movement. It also serves as a absorbent foam media to control backpressure to prevent either a flood or starvation of ink through the head and aids in consistent, predictable flow on demand.
