Flax Fiber:
A Smarter Choice for Pultrusion
Flax has been used in textiles and industrial materials for centuries. Today, it plays a growing role in composite manufacturing as companies move toward cleaner, more responsible material sourcing. We provide a range of flax-based products developed for use in pultrusion and other fiber-reinforced applications. These materials combine natural strength with low density and process reliability, making them a smart fit for industries seeking performance without synthetic inputs.
Advantages of Flax-Based Pultrusion Materials
- Natural Fiber Source - Grown from renewable flax crops with minimal inputs. Free from synthetic additives and naturally biodegradable.
- Engineered for Consistency - Single-ply construction and refined fiber alignment support smooth, uninterrupted feeding through pultrusion equipment.
- High Tensile Strength at Low Weight - Helps reduce overall material weight while maintaining mechanical stability in the final profile.
- Optimized for Resin Compatibility - Performs well with polyester, vinyl ester and epoxy resins. Absorbs resin effectively for strong fiber-matrix bonding.
- Supports Sustainable Manufacturing - Offers a low-carbon alternative to synthetic reinforcements without compromising structural performance.
- Natural Aesthetic & Texture (Optional) - Ideal for visible or semi-structural components where a natural look is desired alongside performance.

Common Applications of Flax in Pultrusion
Flax-based reinforcement materials are used in a wide range of pultruded composite products. They add strength, reduce weight and support a more sustainable manufacturing approach. Typical use cases include:
- Structural Profiles: Window frames, architectural trim and light framing systems requiring low-density reinforcement.
- Furniture Components: Reinforced chair backs, armrests and support bars that benefit from natural fiber texture and strength.
- Sporting Goods: Paddle handles, lightweight beams, or protective gear inserts made with flax-reinforced composite.
- Decorative Profiles: Visible or semi-structural components where natural fiber texture adds to product design.
- Eco-Friendly Panels: Panels for interior design, exhibition structures or green building applications.
- Structural Profiles: Window frames, architectural trim and light framing systems requiring low-density reinforcement.

Advantages of Flax Over Synthetic Fibers:
Lower Environmental Impact - Flax is renewable, requires less energy to produce, and is naturally biodegradable. In contrast, glass and carbon fibers rely on resource-heavy processing and do not break down in the environment.
Lighter Material Weight - Flax fibers offer good mechanical performance at a significantly lower density, which helps reduce the overall weight of pultruded parts.
Health & Safety Benefits - Natural flax fibers are less abrasive and pose fewer inhalation risks during handling, unlike glass fibers which can cause skin and respiratory irritation.
Cost Efficiency in Certain Applications - While not suitable for high-load structural parts, flax can replace synthetics in panels, trim and other medium-strength components at a lower material and disposal cost.
Natural Look & Texture - Flax retains a subtle, organic texture that works well in decorative or visible composite profiles, adding design value without secondary finishing.

Frequently Asked Questions
Is flax strong enough for use in pultruded composites?
What types of resin systems work with flax reinforcement?
Flax performs well with common thermoset resins used in pultrusion, including polyester, vinyl ester, and epoxy. Its natural surface allows for good resin penetration and bonding.
Can these flax products run on standard pultrusion equipment?
Yes, our flax yarns, tow and slivers are compatible with conventional pultrusion setups. Single-ply yarn and aligned slivers feed smoothly into tensioning and resin impregnation systems without additional prep.
How should flax materials be stored before use?
Store in a cool, dry environment away from direct sunlight. Flax can absorb moisture, so sealed packaging or climate-controlled storage helps maintain material integrity and process stability.
What Nm sizes do you offer for yarn, and how do they differ?
We currently offer Nm 2.5 (thicker, 2.5 meters per gram), Nm 6 (medium, 6 meters per gram), and Nm 9.5 (lighter, 9.5 meters per gram) single-ply yarns. The higher the Nm number, the finer the yarn, each designed for different profile dimensions and resin ratios.
Can flax be blended with synthetic fibers in hybrid composite profiles?
Yes, many manufacturers combine flax with glass or carbon fibers to create hybrid profiles that balance sustainability, cost and performance. Flax helps reduce weight and environmental impact while still maintaining core strength from synthetic reinforcements.
