Lubrizol Bio-TPU™

Bio TPU™ by Lubrizol is a revolutionary line of bio-based* TPU (thermoplastic polyurethane) that’s made with renewable-sourced material (content ranging from approximately 30%–70%*). Bio TPU by Lubrizol provides the same performance and benefits as traditional petroleum-based TPU and can range in hardness from 82 Shore A to 55 Shore D.

Products

ESTANE® ECO TPU

This TPU is a bio-based line of polymers made with renewable material content from 29% of total mass (previously known as Pearlthane™ ECO TPU). These resins can be processed through injection molding and extrusion and offer a low density as compared to their petroleum-based counterparts.

Pearlbond™ ECO TPU

Pearlbond™ ECO TPU is Lubrizol’s bio-based TPU with high renewable material content and high thermoplasticity. Pearlbond can be added to reactive hot-melt (HMPUR) formulations to improve crystallization speed and is also used for hot-melt adhesives in heat-sealable fabrics and in toe puffs and counters.
