Abstract:
A patterned thermoplastic elastomer TPE film (10) for fabricating a liquid-filled blister, has a blister-sized cavity (15) in fluid communication with a microfluidic channel (16) via a gating region (14). The gating region is defined by a relief pattern that has at least one of the following: at least 5 separate compartments (20) defined by respective recesses in the first side, each of the recesses bounded by walls (22) that separate the compartments from each other, the recess, or the channel; at least 5 walls defined by the patterning of the first side, the walls separating a plurality of compartments from each other, the recess, or the channel, wherein the walls have a mean thickness that is less than a mean height, and each pair of walls has a mean separation greater than twice the mean thickness; an array of separate compartments bounded by walls defined by the patterning of the first side that collectively define a polygonal regular planar tiling with at least 50% of the surface area of the gating region being open spaces; and a focusing region (16a) in fluid communication with the cavity (15), and a seal region having at least one wall defined by patterning of the film, wherein the at least one wall separates the focusing region from the seal region, and a shape of the at least one wall tapers the focusing region towards the seal region.

Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von zumindest zweilagigen thermoplastischen Schaumstoffplatten durch symmetrisches Verbinden von mindestens zwei dünneren thermoplastischen Schaumstoffplatten (1,2) zu der zumindest zweilagigen thermoplastischen Schaumstoffplatte. Bei den thermoplastischen Schaumstoffplatten der vorliegenden Erfindung bzw. deren dünneren thermoplastischen Ausgangsplatten handelt es sich vorzugsweise um thermoplastische Extrusionsschaumstoffplatten. Das symmetrische Verbinden erfolgt vorzugsweise durch symmetrisches, thermisches Verschweißen. Weiterhin betrifft die vorliegende Erfindung die thermoplastischen Schaumstoffplatten als solche, die zumindest zweilagig sind.
Abstract:
An object of this invention is to provide a highly insulating film, which is excellent in the heat resistance and has increased breakdown voltage. This invention is a highly insulating film, which is characterized by comprising a biaxially stretched film containing a styrene polymer having a syndiotactic structure as a main component, containing a thermoplastic amorphous resin Y having a glass transition temperature Tg by DSC of 130°C or higher in an amount of 5% by mass or more and 48% by mass or less, and having a plane orientation coefficient (”P) represented by the following equation (1) of -0.027 or less. ”P=(Nx+Ny)/2-Nz (1) (Here, in the equation (1), Nx represents the minimum value of the refractive index in the plane direction of the film, Ny represents the refractive index in the direction perpendicular to Nx in the plane direction of the film, and Nz represents the refractive index in the thickness direction of the film.)
Abstract:
A method of sealing a container and a lid by melt adhesion by laser, wherein either the container or the lid comprises a thermoplastic resin that permits the laser beam to transmit through and the other one comprises a resin composition of the thermoplastic resin containing a heat-generating substance that generates heat upon absorbing the laser beam, the laser beam is capable of applying a rectangular beam having a uniform intensity distribution, the upper-limit of temperature that is elevated by the application of laser beam lies in a range of not lower than a melting point of the thermoplastic resin but lower than a thermal decomposition start temperature thereof in the melt adhesion interface between the container and the lid, and the temperature reaches the upper-limit in a heating time t (msec) represented by the following formula (1), t msec = L / S wherein L is the length (mm) of the rectangular beam in the scanning direction, and S is the rate of laser scanning (mm/msec) of not higher than 1.65 mm/msec. The sealing method makes it possible to reliably seal the container and the lid together in a short period of time without causing foaming in the resin that constitutes the container and the lid.
