Custom Blending



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.

Many composites are designed based on stiffness and weight metrics. Bamboo fiber composites have specific modulus values that are very similar to glass fiber composites. This enables Bamboo fiber to be easily integrated into existing design criteria.
