Frequently Asked Questions | FAQs

What is tenacity of a material?

Tenacity refers to the strength and toughness of a material, typically a fiber or a yarn, and its ability to resist breaking or stretching under tension or stress. In other words, tenacity is a measure of how much force a material can withstand before it breaks or deforms.
The tenacity of a material is typically expressed in grams per denier (g/d), which is the weight in grams of a fiber or yarn per 9,000 meters. For example, if a fiber has a tenacity of 4 g/d, it means that a single filament of that fiber with a length of 9,000 meters can support a weight of 4 grams before breaking.

Common high tenacity fibers include aramids, such as Kevlar and Nomex, and high-strength polyesters, such as Dyneema and Spectra.
