摘要:
A resin coated metal sheet 1 includes a metal sheet 2, a resin coating layer 3 formed on the front side of the metal sheet 2, and a resin coating layer 4 formed on the back side of the metal sheet 2. The resin coating layer 3 and the resin coating layer 4 are positioned outside and inside a metal container after forming, respectively. The resin coating layer 3 is formed of a resin material whose difference between the heat quantity of crystallization and the heat quantity of fusion after being laminated to the metal sheet is within a range of 0 J/g or more and 20 J/g or less on a unit weight basis. It is preferable that the resin coating layers 3 and 4 are formed of a resin material containing 90 mol% or more ethylene terephthalate unit and that the melting point of the resin coating layer 3 is within a range of 240°C or more and 254°C or less.

摘要:
The present disclosure provides a thermosetting resin composition including a polymaleimide prepolymer and a poly (arylene ether) prepolymer characterized in that a resultant cured product formed by curing the thermosetting resin composition possesses high heat resistance and low dielectric loss at high frequency. The thermosetting resin composition is especially suited for use in high speed printed circuit boards, semiconductor devices and radome composites for aerospace applications.
摘要:
A barrier packaging material containing a composite which comprises i) a cellulosic layer; ii) at least one metal layer which will dissolve under alkaline conditions; and iii) at least one polymer layer, in which the polymer is hydrolysable under alkaline conditions. The invention also relates to articles comprising the barrier packaging material. Further, the invention concerns the use of a polymer, which is hydrolysable under alkaline conditions, as a protective layer in barrier packaging products. In addition the present application is also concerned with a method for recycling the aforementioned barrier packaging products. Specifically the barrier packaging products are initially taken in an aqueous wastepaper suspension which is either pulped in an alkaline medium and/or treated in an alkaline medium in a deinking process and in which the metal and polymer are then separated from the cellulosic fibres contained in the cellulosic layer.
摘要:
A metal sheet, inclusive of a metal strip, having a front side and a back side, both the front side and the back side comprising a first coating having an average thickness in the range from 0.5 to 10 mum, wherein the first coating of the front side contains particles, which release divalent or multivalent metal ions upon the action of an acid, in such an amount that a self-depositing coating agent forms, upon contact with the front side, a second coating thereon, whereas this is not the case for the first coating of the back side. The first coating of the front side can be overcoated with a self-depositing coating agent. Cut edges that do not have a first coating can be covered with the self-depositing coating agent. Correspondingly coated metal sheets, as well as a method for the manufacture thereof, are furthermore within the scope of the invention.
