Title
(EN) MULTICOMPONENT THERMOPLASTIC PRODUCT
(FR) PRODUIT THERMOPLASTIQUE À COMPOSANTS MULTIPLES
Abstract
(EN)
The present invention relates to a multicomponent plastic product comprising at least two different thermoplastic materials, wherein a first thermoplastic material comprises a first thermoplastic polymer, and a second thermoplastic material comprises at least a second thermoplastic polymer and at least one degrading enzyme able to degrade the first thermoplastic polymer. The second thermoplastic material has a transformation temperature (Tf) lower than the transformation temperature (Tf) of the first thermoplastic material, and the first and second plastic materials are at least partially adjacent in the multicomponent product.
(FR)
La présente invention concerne un produit plastique à composants multiples comprenant au moins deux matériaux thermoplastiques différents, un premier matériau thermoplastique comprenant un premier polymère thermoplastique, et un second matériau thermoplastique comprenant au moins un second polymère thermoplastique et au moins une enzyme de dégradation capable de dégrader le premier polymère thermoplastique. Le second matériau thermoplastique a une température de transformation (Tf) inférieure à la température de transformation (Tf) du premier matériau thermoplastique, et les premier et second matériaux plastiques sont au moins partiellement adjacents dans le produit à composants multiples.
