摘要:
The present invention relates to natural-colored and pigmented thermoplastic molding compositions and molded parts fabricated therefrom that are laser-absorbing at least in partial spectral regions of the wavelength range from 700 to 1200 nm and that can be welded by laser beam welding and to molded parts that are transparent or translucent to laser light.
摘要:
A method of connecting (fixedly joining/attaching) a shaped metal part and a shaped thermoplastics part together is disclosed. The method includes: (a) contacting a surface of the shaped metal part with a surface of the shaped thermoplastic part, thereby forming a contact region; and (b) melting a portion of the shaped thermoplastic part in the contact region by irradiating the shaped metal part with a laser (e.g., emitting a laser beam), thereby fixedly joining the shaped metal part and said shaped thermoplastic part together. Also disclosed is a plastic/metal composite article prepared by the method of the present invention.
摘要:
This invention relates to substance mixtures for thermoplastic molding compositions, comprising A) polyamide and/or copolyamide, B) copolymers of at least one olefin and of at least one acrylate of an aliphatic alcohol, C) additives with chain-extending effect and D) impact modifiers and optionally also E) other additives and/or F) fillers and reinforcing materials. The invention further relates to processes for producing molding compositions of the invention and molded products or semifinished products which are produced from the substance mixtures of the invention, preferably by means of extrusion or blow molding of the molding compositions to be produced from the substance mixtures.
摘要:
A multicomponent system is provided, composed of a thermoplastic component and of a rubber component, which comprises at least two different peroxidic crosslinking agents with specific decomposition temperatures, as also is a process for production of rubber-thermoplastic composite mouldings using the multicomponent system, and also the resultant rubber-thermoplastic composite mouldings.
