Whiteboard Marker Nibs and Reservoirs

Maximum Ink Utilization Combined with Leak Protection

Optimize Ink Flow Management for Whiteboard Markers

As a global leader in the science of ink flow management, Porex has a broad portfolio of products to optimize your whiteboard marker’s performance. Porex whiteboard marker nibs are designed with the perfect porosity and capillarity for the smoothest user experience. When paired with our reservoirs, which utilize optimal fiber type, density and wrap for your marker, users can maximize ink flow delivery and utilization while having the highest degree of leak protection possible. This combination creates the ultimate ink flow management engine that is tailored to your specific needs.

Porex offers two distinct nib technologies for use in whiteboard markers depending on the specific design needs of the marker:

  • POREX® EveraNib™ combines the best features of POREX® sintered PE nibs and POREX® fiber nibs for smoother feel and greater durability, but without fraying or squeaking over time.
  • POREX® polyester fiber nibs are compatible with most inks and are a combination of polyester fiber and bonding resin, optimized for high ink flow and shaped to your whiteboard marker’s specifications.

Manufactured into nearly any imaginable shape, both types of nibs for whiteboard markers are designed to work in tandem with reservoirs to deliver a consistently high ink flow.

Porex offers two distinct reservoir technologies for use in whiteboard markers depending on the specific design needs of the marker:

  • POREX® High Efficiency Reservoirs reduce ink waste, and improve end-of-life indication while enhancing performance, which is ideal for high-cost inks.
  • POREX® XPE® Reservoirs are formed from a controlled density of fibers in an extruded seal, allowing you to contain and deliver the maximum amount of ink to your whiteboard markers.
