Lubrizol launches new bio-based TPU for hot melts and extrusion

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

Lubrizol expands its bio-based TPU portfolio for adhesives.

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. It is designed for improved processability, compared to previous existing HMAs solutions, and has wide wettability.

In addition, the new grade is a bio-based resin with high bio content of up to 59%, as determined according to ASTM D6866. The resin can be processed by extrusion, which is different from previous bio-based HMA polymers available in the market.

Pearlbond ECO 590 HMS TPU can be applied in furniture, edge banding, electronics, hot melt film, textile lamination, seam tape, footwear, and transportation.

Lubrizol’s Bio TPU portfolio, commercialized as ESTANE and Pearlbond ECO TPU, is based on three strong pillars, including Bio TPU, biomass balanced and post-industrial recycled TPUs.
