Stahl Launches Next-Generation Solutions For Lightweight Automotive Leather

Waalwijk, The Netherlands – Stahl, an active proponent of responsible chemistry, has launched a range of next-generation solutions that enable tanners to produce lightweight automotive leathers without compromising on quality.

The new Stahlite® range is designed for use in the re-tanning and fat-liquoring stages of the wet-end leather production process and replaces conventional re-tanning and softening agents with specialty polymers. These polymers penetrate more thoroughly into the leather fiber structure to coat the fiber bundles and fibrils with a smooth layer.

The result is a lightweight automotive leather that, compared with traditional leather, delivers weight savings of 7 kg to 8 kg – or up to 30% – in a luxury car with a full leather interior. This reduces the weight premium associated with a traditional leather interior and contributes to reduced fuel consumption in fossil fuel vehicles and extended range in EVs. Lightweight automotive leather also reduces CO2 emissions by 0.4 g/km to 0.5 g/km compared with a conventional leather interior.

Lightweight leather with superior technical specifications

Stahlite® lightweight leather feels thick, luxurious, and soft, while retaining the durability and long life-expectancy automotive manufacturers and their customers expect. Leather made with Stahlite® maintains good grain tightness, plus the stability and tear strength are the same as standard leather. Leather made with Stahlite® also withstands the effects of heat and oxidation better than a traditionally retanned and fatliquored leather, and it is extremely low-odor and low-VOC as well.

Low environmental impact, high efficiency

With the Stahlite® range, tanners can shorten their retanning time by up to 40% compared with the traditional process. The exact gains depend on the raw material and the final article to be produced. Stahlite® also has a lower impact on the environment. Along with fewer chemicals, it requires less water and energy to produce leather made with Stahlite®, and using Stahlite® creates less wastewater. In concrete terms, the Stahlite® range can reduce COD by up to 40-50% and reduce BOD5 by 60-70% in like-for-like comparisons.

The Stahlite® range is part of Stahl’s Stahl Neo® portfolio of low-impact leather chemicals and complies with the Zero Discharge of Hazardous Chemicals (ZDHC) Manufacturing Restricted Substance List (MRSL).

Stahl’s leather finishing portfolio helps leather manufacturers achieve a range of high-quality finishes in a safe and responsible way. Stahl’s chemicals meet international safety and environmental requirements, including the Zero Discharge of Hazardous Chemicals (ZDHC) Manufacturing Restricted Substances List (MRSL). Many of Stahl’s leather finishing solutions are included in the above-mentioned low-impact Stahl Neo® portfolio.
