BASF has introduced Haptex® 4.0, a 100% recyclable polyurethane solution for the production of synthetic leather. By employing an innovative formulation and recycling technical pathway, it is possible to recycle synthetic leather composed of Haptex 4.0 and polyethylene terephthalate (PET) fabric without the necessity of a layer peel-off process. This enables the materials to be repurposed.
The industry has been grappling with the challenge of reusing or recycling end-of-life synthetic leather for an extended period of time due to its composition of numerous raw materials, such as polyurethanes (PU) and PET. The bonding strength of each layer is exceedingly strong, rendering it challenging to separate them layer by layer. Historically, the reuse or recycling of synthetic leather has been a challenge due to its complexity. However, Haptex 4.0 has the potential to address this issue. Haptex 4.0 is also produced without any waste residue, which results in a more sustainable manufacturing process, due to its recyclability.
“Haptex 4.0 is a technical breakthrough and aligns with BASF's commitment to advancing circular economy principles and promoting the use of recyclable materials in various industries. With Haptex 4.0, BASF is setting a new benchmark in enabling the green transformation of our customers with sustainable, high-performance and durable materials.” said Silvia Mok, Vice President, Business Management Polyurethanes Systems, Performance Materials Asia Pacific, BASF.
Haptex 4.0, like its predecessors, ensures compliance with rigorous volatile organic compounds (VOC) regulations by eliminating the use of organic solvents during the manufacturing process. This substantially streamlines and expedites the synthetic leather manufacturing process.
Haptex 4.0 is an optimal choice for a diverse array of applications due to its affordability and durability, in addition to its environmental advantages. The exceptional anti-yellowing properties, heat resistance, and resilience under autoclave conditions of Haptex 4.0 have been demonstrated through rigorous testing. From footwear and fashion to automotive interiors and furniture, Haptex 4.0 offers exceptional quality and longevity, offering consumers a cost-effective and dependable alternative to traditional leather that does not compromise on performance or cost.
Haptex's initial generation was introduced in 2013 and has since been extensively implemented in various sectors, including automotive, apparel, footwear, and furniture.
