Sunstrand fibers are collected from the inner bark surrounding the core of bast fiber plants such as hemp and kenaf. The fibers are stripped from the core of the plant and processed into groups of single strands. These flexible and resilient fibers have been used for centuries in hundreds of applications. These fibers can be further processed for use in rope, yarn, absorbents, composites, textiles, non-woven/chopped-strand mats, textiles, insulation, and many more.

Combining low density and high strength, the specific properties of Sunstrand’s fibers are similar to glass fiber. Our unique line of Bamboo fiber also has one the lowest densities of all natural fibers.

All natural fibers exhibit lower strength and stiffness properties than glass fibers. However, with densities almost half that of glass, the specific properties are very similar. Moreover, our proprietary fiber extraction process delivers consistent, high-quality fibers at the lowest possible cost.

When increasing the fiber volume ratio to match modulus, natural fiber composites actually have a lower weight than the comparable glass fiber composites. Increases in natural fiber content also have other unique benefits such as increased environmentally friendly content, reduced costs, and tool wear.
