Method of making a shaped article (5) comprising at least two parts (10, 15) wherein the first part comprises at least one projection (20) and the second part comprises at least one recess (22) by preparing said first part and said second part in a moulding process and joining the prepared first and second part together by engaging the at least one projection with the at least one recess to form said shaped article.

Described herein are resilient floor coverings produced by using digitally printed UV-cured inks and exhibiting high adhesion properties between an ink layer and a wear layer. Also described herein are methods for manufacturing same. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The present invention discloses a lithium replenishing diaphragm and a preparation method for the lithium replenishing diaphragm in the technical field of lithium batteries. The lithium replenishing diaphragm comprises in mass percentage: 50-60% of a halogen high-molecular polymer base material, 5-10% of a toughening agent, 5-10% of a flame retardant, and 20-40% of a lithium salt. During the preparation process, the proportioned raw materials are uniformly mixed and placed in a feeding device of a film blowing machine, a film is formed by means of film blowing of the film blowing machine, the film is baked in a drying oven and then wound, and the final lithium replenishing diaphragm is obtained. The present invention solves the defects of high cost, poor heat resistance and poor tensile strength of a diaphragm in the prior art, which can not only greatly reduce the corresponding cost, but also ensure a better thermal stability and a higher toughness of a final product.

The present invention is directed to a packaging material free from aluminium in the form of a continuous foil or film, comprising a layer of microfibrillated cellulose (MFC), wherein the layer comprising MFC has been laminated or coated on at least one side with a heat-sealable material. The MFC layer contains at least 60% by weight of microfibrillated cellulose. The present invention is also directed to a method for induction sealing, wherein a packaging material to be heat-sealed by induction is placed against an induction heating surface.

Compositions may further comprise other components, such as a curing agent and a blowing agent. Articles may include a polymer composition prepared from an ethylene vinyl acetate copolymer, a rubber, and a plasticizer. Methods may include mixing an ethylene vinyl acetate copolymer, a rubber, and a plasticizer; and extruding the mixture thereof.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A method of manufacturing a mat is provided. The method involves securing a first layer formed of a polymer within a base die, positioning an intermediate cushion layer on top of the first layer, securing a second layer formed of the polymer to the base die, and securing a perimeter of the first layer to a perimeter of the second layer by radio-frequency welding, so as to envelop the intermediate cushion layer within the first and second layers and thereby form the mat. The first layer has a first surface and an opposing second surface in contact with the base die. The intermediate cushion layer has a first surface and an opposing second surface in contact with the first surface of the first layer. The second layer has a first surface and an opposing second surface in contact with the first surface of the intermediate cushion layer.
