Title (EN) THERMOPLASTIC ELASTOMERS DERIVED FROM DE-VULCANIZED RUBBER
(FR) ÉLASTOMÈRES THERMOPLASTIQUES DÉRIVÉS DE CAOUTCHOUC DÉVULCANISÉ
Abstract:
(EN) A thermoplastic copolymer is made by first de-vulcanizing a sulfur-crosslinked elastomeric material to produce a liquid phase component. The liquid phase component is subsequently mixed with a compatible thermoplastic polymer at a temperature above its melting point thereof, and the resulting mixture is cooled to produce a solid product.
(FR) Un copolymère thermoplastique est obtenu par dévulcanisation d'un matériau élastomère réticulé au soufre pour produire un composant en phase liquide. Le composant en phase liquide est ensuite mélangé avec un polymère thermoplastique compatible à une température supérieure à son point de fusion, et le mélange obtenu est refroidi pour produire un produit solide.
