In the retanning sector, Lanxess has introduced Levotan PS 100—produced at Lanxess’ Wuxi Chemicals Co., Ltd. in Wuxi, China—a powder polymer which is used at low pH values before rechroming and which is said to impart outstanding leather properties such as extreme tightness. The product is not only suitable for firm articles, it also produces a very fine and even pattern over the whole area of the crust when used for milled upper articles, thus increasing the cutting yield. By combining Levotan PS100 with suitable syntans it can also produce leather with a ‘vegetable type’ character to meet the highest fashion standards and it is also suitable for waterproof leather, especially in combination with Lanxess’ new polymers LubritanXB/XS.
