Italian company Industrie Chimiche Forestali S.p.A (Forestali) has developed a new composite material for the leather goods industry using a special grade of thermoplastic polyurethane (TPU) from Huntsman (The Woodlands, TX, US). The composite material, which features a durable layer of TPU, is called TINTORETTO and is designed to improve the structural integrity of high-end leather goods such as designer handbags and belts.
Forestali wanted Huntsman’s help to develop a durable material that could be wrapped in leather to form structural components for bags, for example, weight-bearing handles and shoulder straps. Huntsman recommended the use of a polyester-based TPU from its IROGRAN family of products. Originally developed for hot melt calendaring applications, the IROGRAN grade in question is also suitable for multilayer extruding. The end result is a material that is reportedly easy to produce and can be cut in any direction without compromising dimensional stability.
Emiliano Bozzato, R&D manager at Forestali said; ‘The team at Huntsman very quickly understood where we wanted to get to with TINTORETTO and recommended a TPU that was perfect for the task in hand. We’ve worked with Huntsman over many years so we knew they would come up with a practical solution. Using IROGRAN TPU we’ve been able to create a hardwearing but flexible product that appeals to discerning decision makers across the global leather goods market.”
