Belltron®

Belltron®
Conducting Anti-Static Fiber

I. Fiber Description
Belltron®anti-static conductive fibers are available in more than 20 combination of colors, polymers, etc offering a wide range of choices in accordance with intended uses and purposes. Static control is offered by blending small amounts of Belltron®into the primary fiber of choice. Belltron® also offers superior abrasion resistance due to the impregnated nature of the elements that offer the anti-static properties. While other anti-static fibers are available, most of them are based on coating (which leads to shedding) instead of impregnation technology. Belltron® is not a laminated fiber, but rather a nylon or polyester fiber containing continuously-embedded anti-static particles which are exposed to the outer surface of the fiber. This novel structure gives Belltron® outstanding anti-static properties as well as excellent physical properties. Since Belltron’s® fiber surface is smooth, unlike carbon-coated fibers, almost the same process ability as regular nylon can be expected. Finally, Belltron® is also available with a polyester matrix polymer (Type B31, B32, BR1, B68) which offers greater acid and heat resistance compared to the nylon Belltron® versions. Applications include: industrial apparel, dust-free garments, carpets, blankets, curtains, static-free brushes, etc.
