Bio-based TPU | Harnessing the Power of Plants to Open a New Chapter of Circularity

Dongrun Technology's bio-based TPU features a 66% high bio-based content as its environmental core, paired with an ultra-wide hardness range of 65A-72D to achieve a multi-dimensional balance of elasticity, support, and durability, providing the footwear industry with a one-stop eco-friendly material solution ranging from skin-contact components to high-load structures.

Environmentally Friendly

The core raw materials are derived from renewable resources such as plant-based polyols, replacing traditional petroleum-based materials to reduce dependence on fossil resources at the source, aligning with the green development trends of the footwear industry.

The full life-cycle carbon footprint is reduced by over 30% compared to traditional TPU, achieving a significant carbon reduction effect through a high bio-based content, helping brands meet the requirements for environmental certifications and low-carbon product portfolios.

It features excellent recyclability, supporting physical crushing for reuse or chemical recycling and repolymerization, reducing waste generation through closed-loop utilization, while the production process is green and low-consumption, imposing no additional environmental burden.

Core application scenarios in the footwear industry

Sneaker midsole: Achieves a combination of lightweight and high rebound through a foaming process, enhancing cushioning and energy return during sports, and is suitable for professional footwear such as running shoes and basketball shoes.

Upper and Support Structure: Made of lightweight TPU film or sheets, used for upper overlays and tongue supports, offering breathability, wear resistance, and stain resistance to enhance the shoe's texture and practicality.

Functional Components and Accessories: Suitable for transparent shoe labels, shoelaces, heel wraps, etc., enriching the shoe's functionality and aesthetic design with its low-temperature resistance and molding flexibility.
