Bio based Resin

About

Invention Summary: The use of bio-based resins and/or natural fibers in composites has emerged due to the need for improved chemical sustainability and environmental impact. There is growing interest in polyurethanes as they are durable and cost effective. However, they are traditionally made from petroleum based polyols and isocyanates. Ulven et al answer the need for sustainable materials with the development of structural biocomposites comprising cellulose-based bast natural fibers and/or glass fibers and bio-based polyurethanes. Specifically, bio-based polyols are reacted with polyisocyanates to generate bio-based polyurethanes. These materials have a higher modulus, hardness, and Tg than other bio-based and petroleum-based polyols.   Benefits: Improved modulus, hardness, and Tg compared to other bio-based and petroleum based polyols Unique properties when combined with natural fibers, such as flax, due to natural compatibility Strong interfacial properties with very little surface treatment to the natural fibers, unlike with petrochemical based resins  Broad applications in automotive and construction markets such as seat frames, truck box panels, sun shades, and door panels   Technology: The technology includes the structural biocomposites in addition to methods of making the materials.   Patents: This technology is patent pending with US and Canada patent applications and is available for licensing/partnering opportunities.
