Innovate with nature.

Powered by wool - engineered for now and the future

Shear Edge leads the development of wool-based plastic technology for practical, sustainable manufacturing in New Zealand and globally

Plastics are essential to modern life - but they have come at a cost. At Shear Edge, we’ve developed a breakthrough composite that reduces plastic content by integrating strong wool fibre into polymer compounds. The result is a high-performance material that’s stronger, lighter, harder, and more sustainable.
We help global manufacturers of plastics and advanced composites unlock new opportunities by reducing their reliance on synthetics and embracing renewable fibres to deliver products that perform without compromise. From outdoor gear and lifestyle products to industrial equipment and packaging, our composites can be applied across almost any rigid plastic product, and can fit seamlessly into existing production lines, providing manufacturers with a world-leading edge.

If you are considering a switch or want to see how our wool-based plastic compound technology fits your business, contact us to discuss your options.
About Shear Edge: Shear Edge is a materials technology and manufacturing business based in Auckland, New Zealand, producing wool fibre composite plastic compounds for manufacturers and working with partners in New Zealand and worldwide. Learn more.
