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.
