Wool-based composites for reliable performance in industrial plastics
Switching to plastic alternatives often raises concerns about weaker materials or higher production costs. Shear Edge wool reinforced polymer composites solve this by increasing rigidity and tensile strength.
Your manufacturing process remains unchanged, with no new equipment or retraining needed. Every batch is tailored to your project’s compliance or mechanical requirements and is provided with clear technical data.
You have material data and supply chain transparency up front, making it easier to plan and deliver your next product. For more on how this practical approach was developed, see the Shear Edge story.

Composite materials for rigid, high-performance applications
Shear Edge compounds are designed for components exposed to stress and wear, like automotive, marine, electronics and appliance parts. Unlike other natural fibre materials like bamboo or wood, you do not sacrifice mechanical strength.
High wool content means less plastic in each part, yet you still meet tough use and regulatory requirements. If you want details on sourcing, read about how strong wool is sourced.

Tailored material properties for your needs
You benefit from higher flexural modulus, tensile strength, increased rigidity and improved insulation and fire performance. Wool content is set up to 30 percent, so you choose the balance of strength and flexibility that fits your application.
This approach means you use less plastic and often see improved technical results.

Seamless integration into your manufacturing
Switching to wool composites does not slow down production or add cost for new machinery. You keep your existing manufacturing lines and just change the resin.
Shear Edge compounds work with moulding infrastructure, so there is no need to alter tooling or process settings. For more on compatibility, see FAQs.

Balanced wool and polymer blends match or exceed many conventional plastics. Each order includes test results and technical specs, so you can design products with reliable data.
Yes. Shear Edge materials are designed for existing equipment in almost all cases. Test batches confirm fit and finish and you receive clear process notes to avoid unwanted changes.
Wool-based composite materials work well in all plastic applications.
You receive documentation for responsible sourcing and compliance audits. For details on fibre management.
