The photochromic helmet visor includes a transparent piece, an adhesive layer attached to the transparent piece, a flexible base layer attached to the adhesive layer, a self-repairing layer attached to the flexible base layer, and a number of photochromic elements integrated with the flexible base layer or the self-repairing layer. The self-repairing layer includes a. PU layer and a. Siloxane layer attached to the PU layer. The photochromic elements are integrated with the flexible base layer or the self-repairing layer. The flexible base layer is made of PU, TPU, PVC, or PET, and may be tightly and smoothly joined to the transparent piece along with the adhesive layer. The self-repairing layer allows self-repairing to scratches or abrasions under a high temperature, thereby preventing the malfunction of the photochromic elements out of wear and usage and the resulted constant replacement, and enhancing the visor's durability.

An infrared stealth cloth includes a cloth substrate and an infrared light absorber located on the cloth substrate. The infrared light absorber includes a first drawn carbon nanotube film, a second drawn carbon nanotube film, and a third drawn carbon nanotube film stacked on each other. The first drawn carbon nanotube film includes a plurality of first carbon nanotubes substantially extending along a first direction. The second drawn carbon nanotube film includes a plurality of second carbon nanotubes substantially extending along a second direction. The third drawn carbon nanotube film includes a plurality of third carbon nanotubes substantially extending along a third direction. The first direction and the second direction form an angle of about 42 degrees to about 48 degrees, and the first direction and the third direction form an angle of about 84 degrees to about 96 degrees.

A method for making a layered structure without any defects, including a first support layer, a second support layer, and an adhesive intermediate layer interposed between the first layer and the second layer which is adapted to fix the layers on each other. The intermediate layer embeds operatively at least a three-dimensional macroscopic element being made of crystal glass or precious stones, and the intermediate layer is made of a thermoplastic resin having a melting temperature.

To provide a process for producing a film excellent in water vapor barrier property, tensile elongations, and transparency. A resin material containing polychlorotrifluoroethylene (PCTFE) is melted and extruded into a film from an extrusion die, the extruded product is brought into contact with a cooling roll having a surface temperature of at most 120° C. in a state such that the surface temperature of the extruded product is higher than the crystallization temperature of PCTFE to form a film web, and the film web is subjected to heat treatment at from 80 to 200° C. to obtain a film.

A laminated vehicle glazing with includes a first extraclear glass sheet forming an exterior glazing, a lamination interlayer and a second glass sheet forming an interior glazing with a traversing hole in these last two.

Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising, consisting essentially of, or consisting of low-density polyethylene, optionally linear, and at least about 80 wt. % of high-density polyethylene, as well as a second skin layer comprising either: (i) one or more low-density polyethylenes, any or all of them optionally being linear; or (ii) one or more polypropylene-based copolymers. The multilayer film may be oriented in at least one direction.

The present disclosure relates to a polyester resin blend, a polyester film and a preparation method of the same. The polyester resin blend is capable of providing a heat shrinkable label that is transparent and has excellent shrinkage even if it contains recycled polyethylene terephthalate as well as virgin polyethylene terephthalate. In addition, the heat shrinkable label can be reused while attached to a PET container, etc., and is expected to be useful for providing continuously usable plastics that have been recently attracting attention.

A freezing packaging film having transparency that produces a color difference (ΔE) of 30 or less on a surface of contents when subjected to frozen storage at −20° C. for 2 weeks, the contents being a reagent containing 0.14 mass % of methylene blue and having L* of 55 to 65, a* of 3 to 9 and b* of 45 to 55 in a L*a*b* color system.

A flexible display apparatus includes a first functional layer, a second functional layer above the first functional layer, a third functional layer above the second functional layer, a first adhesive layer between the first functional layer and the second functional layer, and having a first recovery rate, and a second adhesive layer between the second functional layer and the third functional layer, and having a second recovery rate that is lower than the first recovery rate.

A process for making a card includes the steps of forming a core layer having a first surface and a second surface, disposing an uncured decorative ceramic layer of ceramic particles disposed in a resin binder over the first surface of the core layer, such as by spray coating, and curing the uncured decorative ceramic layer to form a cured decorative ceramic layer. Card products of the process may have a core layer of metal, ceramic, or a combination thereof that form a bulk of the card.
