Foam Felt and Wicking Materials
SIF Felt® compressed reticulated foam felts transport fluids from a reservoir to an application surface. The consistent and precise cell structure of SIF Felt® wicking material helps provide excellent, controllable capillary action. Cell strands generally do not break loose or crumble to inhibit the wicking material's action. The capillary wicking properties are a result of reduced average pore size, which is achieved by compressing reticulated foam. Since SIF Felt® is oleophilic, it will hold and transport oils to bearing wear surfaces.
Absorbent Foam Applications
FXI is the world's leading supplier of foam felt for ink jet cartridge wicking materials. Our reticulated fine pore, polyurethane absorbent foam felt is compressed during cartridge assembly. The foam felt then functions as a wicking material to retain and deliver ink consistently to the print head. The foam felt's absorbency helps control backpressure to keep ink flowing smoothly and regularly through the printer head and aids in consistent, predictable flow on demand.
Functions of SIF® Foam Felt
- Inkjet cartridge foam felt wicking materials for ink reservoiring and delivery
- Sponge materials for cleaning surfaces
