The Lubrizol Corporation's Engineered Polymers business has announced the performance upgrade of its Pearlstick(TM) thermoplastic polyurethane (TPU) for adhesives. Pearlstick TPU is an alternative to polychloroprene resins for footwear and DIY end applications.

Room Temperature Contact Bonding

Adhesives formulators apply Pearlstick 45-80/16 TPU and other similar Pearlstick products as a preferred alternative to polychloroprene resins, providing equal or even better performance. The Pearlstick solution brings about improved processing and cost-efficiency thanks to its very long open time and contact bonding at room temperature during the formulation of adhesives. Pearlstick TPU is a more sustainable and safer solution as it can be formulated based on more environmentally-friendly solvents, avoiding, for example, toluene or cycloheptane.

Several benefits with Multiple Materials


As it relates to the processing, Lubrizol TPU for adhesives can be applied on just one substrate - there is no need to apply it to both sides to achieve final bonding, as in the case of polychloroprene. Pearlstick TPU grades offer a wider range of adhesion possibilities to various materials. They also provide a very low crystallization rate, good heat resistance and peel strength.

"Our customers are looking to manufacture contact adhesives that offer a cost-effective adhesive solution with formulation flexibility. Lubrizol's Pearlstick TPU offers high-performing features and a robust and consolidated technology to satisfy these needs", states Jesus Santamaria, Regional Business Director EMEAI Engineered Polymers.
