POREX Boruikes is a global leader in advanced porous solutions and a subsidiary of the Filtration Group. It was founded 63 years ago in a small building on Bay Street in Fairburn, Georgia.

A history of breakthrough innovation and complete reliability
For over 60 years, POREX® pen tips and ink reservoirs have set the standard for consumer expectations for writing instruments of all shapes, sizes, and types. As a global leader in the science of ink flow management, our engineers design pen tips combined with ink reservoirs to create an optimized system that maximizes ink delivery and control while preventing leaks. The perfect porosity and capillarity of the tips, together with the ink reservoirs, are matched with the best fiber types, densities, and packaging materials specifically designed for your ink and pen body. This quality and consistency have helped the world’s largest writing and printing manufacturers build their brands and earn customer loyalty.

Creating better end products faster and with fewer resources
With Porex as your resource in ink flow management science, our expert team relies on years of experience in pore volume, pore size, capillary action, fluid dynamics, and chemical interactions as a basis for system design, optimizing the combination of pen tips and ink reservoirs. POREX’s proprietary testing methods measure ink flow and pen performance, focusing on your key performance metrics like ink laydown, leakage, ink longevity, uncapping time, and ink settling.

POREX’s Excellence Center in Ningbo, China, was established in 2003 and is dedicated to developing reservoirs for the writing instrument and cosmetics markets. The factory also produces porous components widely used in IVD, printing systems, home products, medical, and life sciences applications. The in-house engineers in charge of research and development contribute to the plant’s progress and growth.

Boruikes Specialty Fibers (Ningbo) Co., Ltd.
The Ningbo plant has 20 years of experience in fiber production and manufacturing and moved in 2019 to a new 8,799-square-meter facility, double the previous space. This expansion aimed to increase capacity, better serve Asian customers, and work closely with Porex’s global factories to develop the most effective porous fiber solutions.
