The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

An apparatus and method of closing a wide variety of thermoplastic tubes, in particular with Shore hardnesses of around 50 (A) to above 100 (A), where the tubes having inside diameters of 1.6 mm to 35 mm and/or wall thicknesses of 0.8 to 4.8 mm. The method involves use of a tube heater having at least one heating element. The heating element has at least four heatable regions which are movable with respect to one another. The tube heater is configured to enclose, in the applied state, at least 75% of the circumference of the tube while bearing against the latter over its circumference at at least four points which are spaced apart from one another. One of the key advantages is that, prior to compression, the tube can already have been heated at a plurality of points on the tube.

A thermoplastic laminate plank is described wherein the thermoplastic laminate plank includes a core, a print layer, and optionally an overlay. The core includes at least one thermoplastic material and has a top surface and bottom surface wherein a print layer is affixed to the top surface of the core and an overlay layer is affixed to the top surface of the print layer. An underlay layer can be located and affixed between the bottom surface of the print layer and the top surface of the core. In addition, a method of making the thermoplastic laminate plank is further described which involves extruding at least one thermoplastic material into the shape of the core and affixing a laminate on the core, wherein the laminate comprises an overlay affixed to the top surface of the print layer and optionally an underlay layer affixed to the bottom surface of the print layer.

Provided are multi-beam meltblowing apparatuses having a ridged collecting surface, methods for making multilayer meltblown composites using such apparatuses, and multilayer meltblown composites made therefrom. Also provided are a multilayer composite comprising an elastic layer and at least one ridged layer and a method for making the multilayer composite.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures. A method includes: placing a first polymeric part in contact with a second polymeric part; and plastically deforming the first polymeric part and the second polymeric part against each other to bond the first polymeric part to the second polymeric part. Additionally, during the plastic deformation, a temperature of the first polymeric part is less than a glass transition temperature of the first polymeric part and a temperature of the second polymeric part is less than a glass transition temperature of the second polymeric part.

A hollow structure for a face mask includes an inner wall, an outer wall spaced from the inner wall to define a hollow area between the inner wall and the outer wall, and a bottom wall that couples the inner wall to the outer wall. A first portion and a second portion together define a closable opening into the hollow area. The second portion is coupled to the outer wall by a bi-stable membrane that allows the second portion to move between (1) a first, opened position in which the second portion is spaced from the first portion to allow access to the hollow area through the opening, and (2) a second, closed position in which the second position abuts the first portion to close the opening.

A plastic component (100) with a substrate (130; 230) comprised of a plastic and at least one first fastening piece (110) that is embodied for a form-fitting engagement with a complementarily formed second fastening piece (210) and has at least one anchoring element (112; 212) for being embedded and fixed in position in the substrate (130; 230); the substrate (130; 230) is comprised of soft foam with a weight per unit volume of 120 kg/m3 to 300 kg/m3 and a Shore A hardness of 5 to 100 and the fastening element (110; 210) is comprised of a thermoplastic plastic.
