Liyang, China – LIYANG PULISEN POLYURETHANE PRODUCTS CO., LTD. announces

the commercialization of its GreenFlex™ Bio-TPU Series, a line of thermoplastic polyurethane pellets containing 95% plant-based feedstocks. This innovation aligns with global circular economy goals while meeting rigorous mechanical requirements in automotive and consumer goods sectors.

Technical Highlights:

Raw Material Composition: 70% castor oil-derived polyester polyol + 25% bio-sourced chain extenders

Performance Metrics:

Tensile strength: 65 MPa (ASTM D412)

Elongation at break: 580%

Shore hardness: 85A–75D

Environmental Impact: 40% lower CO₂ emissions compared to petroleum-based TPU (ISO 14067-compliant LCA)

Market Differentiation:

Unlike conventional "green" TPUs that compromise flexibility, GreenFlex™ achieves superior low-temperature resilience (-35°C brittleness point) through proprietary phase-separation control during synthesis.

Quote from R&D Director:

"Our bio-TPU retains the abrasion resistance and hydrolysis stability demanded by industrial clients while enabling brands to meet EU Ecodesign for Sustainable Products Regulation (ESPR) targets."
