Abstract
Official abstract text for this publication.
A composition, in particular for molding, including a mixture of a polyamide material, a powder made from airbag scraps, and optionally a reinforcing filler. Also described, is an article formed from the composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising a mixture of: a polyamide material; and a safety airbag residue powder, wherein said residue is based on a polyamide comprising a silicone coating, and wherein said powder is a micrometric powder having a particle size D50 of between 50 μm and 400 μm. 2. A molded article obtained by injection molding the composition of claim 1 . 3. The composition of claim 1 , wherein the powder comprises spherical or substantially spherical particles and/or fibrous particles. 4. The composition of claim 1 , wherein the mixture comprises 0.5% to 70% by weight of the safety airbag residue powder relative to the total weight of the composition. 5. The composition of claim 1 , wherein the polyamide material is in the form of virgin polyamide granules or in the form of granules of virgin polyamide comprising a reinforcing or bulking filler and another additive. 6. The composition of claim 1 , further comprising a reinforcing or bulking filler, wherein the reinforcing or bulking filler is selected from the group consisting of a fibrous filler and a non-fibrous mineral filler. 7. The composition of claim 6 , wherein when the filler is a fibrous filler, and the fibrous filler is a glass fiber, a carbon fiber or an aramid fiber. 8. The composition of claim 6 , wherein when the filler is a non-fibrous mineral filler, and the non-fibrous filler is a clay, a kaolin, a mica, a wollastonite or a silica. 9. The composition of claim 4 , wherein the mixture comprises 15% to 50% by weight of the safety airbag residue powder relative to the total weight of the composition.
