The company created this product by combining particular additives with resin that REFINVERSE Group, Inc., recycled by stripping silicone from airbag fabric scrap cuttings. and thereafter washed. The new offering will debut as Ecouse AMILAN™. Toray looks for that offering to accelerate the expansion of Ecouse (pronounced Eco-Use), a proprietary integrated brand for eco-friendly recycled materials and products that it rolled out worldwide in 2015.

The nylon 66 fabric of airbags can be silicone-coated or non-coated. Manufacturers normally recycle the scrap cuttings of non-coated fabrics. Recycling coated airbag fabric scrap cuttings requires removing the silicone. REFINVERSE was the first in Japan to achieve commercial-scale silicone-coated fabric recycling. 

Recycling through stripping and washing has typically left silicone traces, however, degrading the resin and contaminating molds during injection molding. Another issue has been that the high viscosity of airbag yarn limits applications in thin-wall and other injection molding processes in which high fluidity is vital.

Toray accordingly combined particular additives so residual silicone resin would not migrate to the surface of molded products. It also greatly reduced mold adhesion. That is why the flowability and mechanical properties of recycled nylon 66 with Toray’s technique are on par with those of virgin nylon 66.

Toray plans to start full-fledged sample work in April 2023 or later. It ultimately looks to procure recycled raw materials at its overseas sites to establish a global supply system. It will also explore commercializing recycled nylon 66 products made from airbags recovered from end-of-life vehicles.
