Method for forming a body comprising at least one through-going passage
A method is described for forming a body having at least one through-going passage, said method has the steps of: a) providing a mixture comprising particles and at least one liquid pocket inside a curable matrix, b) subjecting said mixture to a first alternating voltage having a first frequency to form a body in which said at least one liquid pocket extends from a first surface of said body to a second surface of said body thereby forming at least one through-going passage lacking curable matrix, and c) curing said curable matrix into a cured matrix, wherein at least some of said particles are located at an interface between said at least one through-going passage comprising liquid and said cured matrix.
Manufacturing a two-part elastomeric plunger
A technique of manufacturing an elastomeric container closure or plunger with embedded functional components to avoid thermal damage to the components is described. The technique includes molding a drug-contacting part from a first material at a first temperature and for a first length of time defining a first thermal exposure; after molding the drug-contacting part, inserting ancillary components into the drug-contacting part, where the ancillary components have an operational thermal budget less than the first thermal exposure; and overmolding the drug-contracting part and the ancillary components with a second material at a second temperature for a second length of time to form a non-drug-contacting part that mechanically connects the non-drug-contacting part and the drug-contacting part to form the elastomeric container closure and seals the ancillary components inside the elastomeric container closure. The overmolding defines a thermal exposure less than the operational thermal budget of the ancillary components.
Multi-layered films for use in airbags and footwear
Airsoles or bladders for articles of footwear comprising multi-layered films are provided herein. In one aspect, the airsoles or bladders comprise a first sheet and a second sheet, wherein a first side of the first sheet faces a second side of the second sheet, wherein the first sheet and the second sheet are bonded together to form an internal cavity in a space between the first side of the first sheet and the second side of the second sheet, forming a bladder capable of retaining a gas in the internal cavity at a pressure above atmospheric pressure, at atmospheric pressure, or below atmospheric pressure; and wherein each of the first sheet and the second sheet comprise a multi-layered film comprising: a core region comprising at least 20 gas barrier layers and a plurality of elastomeric layers, wherein the gas-barrier layers alternate with the elastomeric layers.
In-situ microfibrillated reinforced polymer composite heat-insulating foam material as well as preparation method and application thereof
The disclosure belongs to the technical field of heat insulation materials, and discloses an in-situ microfibrillated reinforced polymer composite heat insulation foam material as well as a preparation method and application thereof. This disclosure adopts a polypropylene matrix, a fiber-forming polymer, an elastomer and an antioxidant as a foam material. The foaming material is subjected to a primary melt blending process and a hot stretching process first, then subjected to a secondary melt blending process and cooling granulation and subjected to a pressing process, and a composite board is obtained. The composite board is subjected to supercritical fluid foaming process, and a composite heat insulation foam material is obtained.
Method for coding a container and coded container
The invention relates to a method for coding a dimensionally stable packaging container or an associated component made of a plastics-based and/or paper-based material composition, the packaging container being suitable for storing consumer goods such as food, washing agents, etc., wherein, during a shape-forming process for forming the three-dimensional packaging container or the associated component by means of a shaping tool mold, at least one outer and/or inner side undergoes, in at least one position, a shape-changing treatment acting on its first surface in order to produce at least one three-dimensional code.
Flame retardant rotomolded polyolefin
Polyolefin hollow articles prepared via a rotomolding process are provided flame retardancy by incorporating therein a phosphonate ester, an N-alkoxy hindered amine and melamine cyanurate.
Core-sheath filaments and methods of printing an adhesive
A core-sheath filament having a non-tacky sheath and a hot-melt processable adhesive core, the sheath exhibiting a melt flow index of less than 15 grams per 10 minutes, is provided. Methods of making the core-sheath filament and methods of using the core-sheath filament to print a hot-melt processable adhesive onto a primer-treated substrate surface to provide a structural bond are described.
