Let us help you discover where & how to use natural fiber reinforced composites in your applications.

Further Sustainability in Thermoforming

EcoRein/W is a thermoplastic-based prepreg reinforced with biaxially aligned flax fibers in the form of woven fabrics. The reinforcing flax fibers are carbon-neutral, renewable, and lightweight; similar to carbon fiber and 40% lighter than glass.

Easy of Handling and Drapability with Pleasing Aesthetics

EcoRein/W prepregs provide orthotropic mechanical properties rather than a maximized performance in one direction as in the case of EcoRein/UD. The interconnected flax fibers within varied weave patterns bring drapability and ease of manual handling.

EcoRein/W prepregs offer solutions to the complex dilemma in the material selection: optimum performance, lightest design, minimum environmental impact, and affordability.

No Additional Thermoplastic Film or Sheet 

EcoRein/W family is suitable for all thermoforming processes (compression molding, vacuum molding, injection overmolding, and automated tape laying). There is no need to use extra thermoplastic film/sheet. Our prepregs are also compatible with non-woven and wovens (natural, glass, basalt, or carbon fiber based), cork, plywood, decorative fabrics, and honeycomb structures.

Polymer, Structure, Weight, and Color Options

We offer two polymer options in EcoRein/W family: polypropylene and polylactic acid. EcoRein/W is available in 100cm wide rolls in twill or plain structures. We have two standard weight options: 300 gr/m2 and 400 gr/m2. Upon request, we can customize weight and width. We do not color flax fibers to eliminate environmental loads, but colored polymer options are available.

Finally, no specific precautions in handling, composite manufacturing, storage, packaging, and transport are required.

EcoRein/W Prepreg Options


High in polymer combination, %35 flax fiber and %65 polypropylene


Combination of %50 flax fiber and %50 polypropylene for high-performance applications


Combination of %50 flax fiber and %50 polylactic acid for ultimate sustainability applications.

The Ideal Replacement in Various Applications

Electrified Mobility Vehicles: Transform your electric mobility vehicle parts into eco-friendly, zero-emission vehicles. You can achieve significant weight and emission reduction in interior trims, urban/micro-mobility vehicles, three-wheelers, cargo bikes, e-bikes, and e-motorbike parts by reducing synthetic materials such as plastics, glass-mat thermoplastics, and glass/PP wovens.

Consumer Products and Sports Equipment: Explore the possibilities of using EcoRein/W in consumer products and sports equipment such as rackets, scooters, boards, bikes, sticks, kayaks, paddles, and other accessories.
