The invention relates to a component comprising an insert part and plastics jacketing composed of at least two plastics components, where the insert part is enclosed by a first plastics component A and there is a second plastics component B enclosing the first plastics component A, where the first plastics component A is composed of: A1: from 5 to 80% by weight, based on the total weight of components A1 and A2, of at least one polyester based on aliphatic and aromatic dicarboxylic acids and on aliphatic dihydroxy compounds; A2: from 20 to 95% by weight, based on the total weight of components A1 and A2, of at least one homo- or copolyester selected from the group consisting of polylactide (PLA), polycaprolactone, polyhydroxyalkanoates, and polyester derived from aliphatic dicarboxylic acids and from aliphatic diols; A3: from 0.05 to 15% by weight, based on the total weight of components A1 and A2, a) of a copolymer which contains epoxy groups and which is based on styrene, on acrylate, and/or on methacrylate, b) of a bisphenol A epoxide, or c) of a fatty acid amide or fatty acid ester, or natural oil containing epoxy groups; and the second plastics component B is composed of B1: from 50 to 100% by weight of at least one semicrystalline, thermoplastic polyester based on aromatic dicarboxylic acids and on aliphatic or aromatic dihydroxy compounds and B2: from 0 to 50% by weight of at least one thermoplastic styrene (co)polymer, in each case based on the polymer content of the second plastics component B.
摘要:
The invention relates to a process for the production of a component, comprising an insert part (1) sheathed by a plastics layer, by, in a first step, sheathing of at least one part of the insert part (1) with a plastics molding composition (2) with low viscosity and, in a second step, using a hard plastics component (3) for overmolding of the insert part with the sheathing, or by sheathing of the insert part (1) with a hard plastics component (3), regions of the insert part (1) here not being sheathed, and overmolding of the non-sheathed regions with a plastics molding composition (2) with low viscosity. The invention further relates to a component comprising an insert part and comprising plastics sheathing which is composed of at least two plastics components, where the first plastics component, which at least to some extent directly sheathes the insert part (1), is a plastics molding composition (2) with low viscosity, and the second plastics component is a hard plastics component (3).
