What is the function of wicking?

Wicking processes span all facets of everyday life. From garments designed to wick sweat, to marking pens that transfer ink to a surface, to devices that collect and test bodily fluids.  The capillary action of a wicking process can allow the movement of fluids in tight spaces without, or sometimes against the force of gravity.

Porex has been designing and developing fluid transfer – or wicking – systems utilizing porous plastic materials for over 50 years. In addition to our material science and component design expertise, we offer a wide variety of base material options – from thermoplastic polymers to synthetic fibers. POREX® wicking solutions are designed with open-cell pore structures that control liquid volume capacity and fluid transfer rates, and our experts have the ability to alter the surface energy of the materials to further enhance media capillarity. Our products are custom engineered to optimize fluid transfer based on specific end-use product requirements.

Using Porous Plastics for Wicking

Problems that porous wicking media can solve:

  • Moving a bodily fluid sample through an in-vitro diagnostic test system
  • Transferring ink from a coloring marker reservoir to the nib (tip) for writing onto a surface
  • Moving liquid to a collection point
  • Collecting a diagnostic test sample such as saliva or urine
  • Sucking up a defined quantity of formulas or chemicals such as makeup so that it can be applied to a surface
  • Drawing oil or water through a reed wick for a home air freshener system

Common applications for porous wicking media

Sample Collection

Pregnancy and Ovulation Test Wicks

POREX® pregnancy and ovulation wicks deliver proven performance and reliability. As the industry standard for home pregnancy and ovulation testing around the world, our products are optimized with precise capillary action, high purity and proprietary color change technology.

Electrolyte Reservoirs

Electrolyte reservoirs and wicks for electronics and sensors

Electrolyte reservoirs and wicks are needed to retain and deliver an electrochemical system’s electrolyte solution to facilitate the chemical reaction. POREX® fiber and foam media can be used for reservoirs, general wicking, and supporting of fluids within electronics and sensors.

Plug-in Air Freshner

Plug-in air freshener wicks

Plug-in air fresheners are designed to deliver fragrances quickly. For more intense and consistent fragrance release, Porex developed a selection of porous fiber and sintered particle wicks that can be customized to the specific requirements of the air freshener.

Specifically designed for plug-in air fresheners, these wicks deliver fragrance from the bottle or container to the heater using capillary action, thereby diffusing fragrance from the wick into the air.

Topical Applicators

Topical applicator wicks for medical drug delivery

POREX® topical applicator filters and wicks are designed for fluid-based application of sealing agents for wound closure, such as surgical incisions or drug delivery in dental treatment applications, and can also serve as wicks if the solutions are mixed and expressed from crushed glass ampoules.

Personal Care & Beauty

Lip and eyeliner reservoirs

Porex designs customized reservoirs for optimized wicking and delivery of any eyeliner, lip liner or lip gloss formulation.  Made entirely from fiber or film sealed wraps, our lip and eyeliner reservoirs combine customized capillary structures with specially designed fiber blends to be compatible with a wide range of formulations.

Print Cartridges

Printer ink delivery wicks

Precisely controlled ink delivery wicks and systems are critical for consistent ink flow within printers. Porex creates customized ink delivery wicks that ensure consistency within ink absorption solutions and remove waste caused from over-spraying.
