In the automotive and aviation industries, every kilogram saved makes a difference in performance and sustainability. Stahl’s fatliquoring polymers, which are included in Stahl Neo® and therefore ZDHC MRSL compliant, reduce the weight of leather. This makes it ideal for both industries. And in other industries, like apparel, opting for lightweight leather is a great way to make a product feel nicer to wear and carry.
