Lubrizol introduces breathable, microbe-resistant TPU grades

Lubrizol has launched two thermoplastic polyurethane resins for hot melt adhesives (HMAs). The products belong to the plasticiser-free Pearlbond 300 TPU series that stands out for its low activation temperatures and good bonding properties to various substrates.

According to Lubrizol, its offering for HMAs can be found in technical textiles, interlinings, apparel (seam tapes and heat-transfer labels), conveyor belts, footwear and many demanding applications. The Pearlbond 360 and 960 TPU resins are said to perform well in outdoor applications thanks to their resistance to external agents (humidity and microorganisms). Pearlbond 360 is a breathable, plasticiser-free soft TPU with good wash resistance and adhesion to fabrics. This solution bonds well at a low activation temperature (< 120 ºC). This allows it to be combined with delicate fabrics and increases the protection of substrates from heat damage. Pearlbond 960 is a light-stable, breathable and plasticiser-free TPU which combines the above-mentioned properties with good UV resistance. It is said to be a durable solution with improved bonding and mechanical properties.

James Ruben, global market segment manager for adhesives at Lubrizol Engineered Polymers, said: “There is a strong demand from customers around the world to have adhesive solutions that combine softness, low activation temperature and high durability. End-uses such as quality garments, automotive and consumer goods require innovative bonding solutions. An increasing number of customers are in search of such a solution. Lubrizol is listening to those customers and is committed to addressing their needs.”
