Hypetex wins Innovate UK Smart grant for FlaxTex composite
In addition to its aesthetic qualities, the novel colored natural fiber is waterproof, 100% biodegradable and features enhanced manufacturing attributes thanks to Hypetex’s coloring process.

Hypetex (London, U.K.) has been awarded a significant grant from Innovate UK to develop FlaxTex, a technical colored flax fiber, which the company says will have applications in the sustainable manufacture of cars, boats and other products that are usually made with carbon fiber.
While strong and lightweight, FlaxTex is also 100% biodegradable, having a net positive carbon footprint at point of manufacturing. In addition, it can be colorized, which simultaneously enhances its performance properties, adding to its manufacturing attributes compared to standard flax fiber. As such, FlaxTex’s mechanical properties are said to represent the closest sustainable substitute for materials like glass and carbon fiber in composite structures.
The performance of standard flax fiber, for example, is often hindered by its high moisture absorption, resulting in reduced structural integrity when used in composite construction. In addition, the natural brown color of flax has sometimes been deemed unappealing.
On the other hand, FlaxTex removes moisture through the coloring process and seals the fibers, which waterproofs them and enables their core mechanical properties. Moreover, Hypetex’s patented nano-pigment color technology adds an aesthetic quality to the material. Ultimately, FlaxTex is meant to transform the industrial design possibilities of flax natural fibers while also reducing post-processing requirements and total energy use.

FlaxTex has a range of industry uses, including construction, automotive, sports equipment and furniture. Over the course of a 12-month industrial research project, Hypetex will further optimize its resin systems and processes, expanding the use of FlaxTex across various markets.
“FlaxTex natural fiber showcases Hypetex’s steadfast commitment to sustainability and our mission to pioneer carbon-neutral materials,” says Marc Cohen, CEO of Hypetex. “We are thrilled to embark on this journey toward a greener future, driving innovation through sustainable composites technology.”
