Lubrizol announces the expansion of its bio-based thermoplastic polyurethane (TPU) portfolio for adhesives with the addition of Pearlbond™ ECO 590 HMS TPU for hot melt adhesives (HMAs).

This high-performing resin from a renewable source can be applied by adhesive formulators or designers in furniture, edge banding, electronics, hot melt film, textile lamination, seam tape, footwear, and transportation.

Pearlbond ECO 590 HMS TPU is a fast-setting solution with good adhesion properties for applications that require a toluene-free and more environmentally friendly alternative, as well as high temperature and hydrolysis resistance. In addition, it is designed for improved processability (versus previous existing solutions in HMAs) and has wide wettability.

“The high thermoplasticity of this new grade and the fact that it can be processed by extrusion, makes all the difference from previous bio-based HMA polymers available in the market” said MariaJosep Riba, global sustainability manager for Lubrizol Engineered Polymers. ”In addition, it is a bio-based resin with high bio content*, up to 59%, which makes it the ideal choice going forward if you are looking for performance and carbon footprint reduction”.

The expansion of the Bio TPU solutions, commercialized as ESTANE^® and Pearlbond ECO TPU, supports the acceleration of Lubrizol’s global sustainability journey. This journey is based on three strong pillars, including Bio TPU, biomass balanced and post industrial recycled TPUs. 

*Bio-based content as determined according to ASTM D6866
