摘要:
A process for the production of polyester-polyamide block polymers by precondensing a polyamide-forming starting mixture until a relative viscosity of at least 1.2 is attained, and adding a polyester, the dicarboxylic acid units of which are derived to at least 50% from dicarboxylic acids having at least 17 carbon atoms.
摘要:
Thermoplastically polyamide moulding compositions produced from at least 70% by weight of polyamide, a long-chain polyester, polyether or hydrocarbon polyol and at most 5% by weight of a polyanhydride or polyepoxide.
摘要:
Easily flowable, impact resistant polyamide moulding composition containing from 0.5 to 10%, by weight, of polyethers preferably modified with (meth)acrylate or primary amino end groups or of polyesters preferably containing (meth)acrylate end groups.
摘要:
A composition comprising 96-99.9% by weight of a highly flame-resistant base oil such as an aromatic phosphate ester or a polychlorinated aromatic compound and a polyester of molecular weight, 20,000 to 300,000, derived from polytetramethylene glycol, for instance. The composition has an improved viscosity index and is especially useful as a HSD lubricant. It is also useful as a hydraulic fluid and/or heat transfer liquid. By addition of such a polyester to such base oil, the viscosity index of the base oil is considerably improved.
摘要:
A halogen-free, phosphorus-free, flame-resistant wrapping foil of polyolefin, comprising carbon black and metal hydroxide, the wrapping foil having an FMVSS 302 horizontal-sample flame spread rate below 200 mm/min, preferably below 100 mm/min, and being in particular self-extinguishing under the test conditions specified in FMVSS 302.
摘要:
Flame-retardant, halogen-free winding film comprising at least one polypropylene copolymer, at least one inorganic flame retardant, and 1 to 30 phr, preferably 5 to 15 phr, of at least one polymer which is incompatible with the polypropylene copolymer.
摘要:
A method of producing a film adhesive tape, characterized in that a composite comprising at least one extruded backing film layer and a pressure sensitive adhesive layer on one side of the backing film layer is biaxially drawn.
摘要:
Halogen-free, flame-retardant winding film made of polypropylene copolymers, useful for wrapping ventilation lines in air conditioning units, wires or cables and for bundling, insulating, marking, sealing or protecting.
摘要:
A data storage medium includes an optical information carrier comprising a spiral-wound polymer film. The central area of the data storage medium is provided with a recess whose periphery is formed by the innermost winding of the polymer film.
摘要:
A data storage medium includes an information carrier wound onto a winding core in a spiral manner for optically readable information units. The winding core is configured in a spiral manner on its outer contour and has a step. The height of the step is matched to the thickness of the information carrier. The inner end of the information carrier rests on the winding core at the step or in the area of the step.
