Lightweight, structurally reinforced thermoplastic objects comprising at least one reinforcement zone are manufactured by providing a heatable rigid forming chamber with a chamber volume. At a temperature below the thermoplastic softening temperature, the chamber is loaded with a plurality of thermoplastic lofting bodies and a plurality of thermoplastic reinforcement bodies wherein the lofting bodies are heat-loftable bodies comprising a thermoplastic matrix containing an elastically compressed assembly of reinforcement fibers embedded therein, lofty non-woven bodies comprising an elastically compressible assembly of reinforcement fibers and thermoplastic fibers. Upon closing the chamber, lofting bodies of lofty non-wovens are elastically compressed, producing an internal pressure. After heating the chamber above softening temperature, reinforcement bodies and lofting bodies are ow thermoplastically formable, and lofting bodies configured as heat-loftable bodies produce a second internal pressure. After a predetermined processing time, the chamber is cooled yielding a structurally reinforced object.

An ultrasonic transducer includes: a laminate in which a plurality of acoustic members is laminated; and an adhesive layer that includes a silane coupling agent and an adhesive, the adhesive layer joining any two of the plurality of acoustic members to each other, wherein the silane coupling agent has a structure represented by general formula (1):

##STR00001##

wherein R.sub.1s each independently represent a methoxy group or an ethoxy group, R.sub.2 represents a methoxy group, an ethoxy group, or a hydrogen atom, X represents a linear or branched organic chain having 4 or more continuous carbon atoms, and A represents a reactive functional group.

Oxygen scavenging polymeric compositions that possess an improved oxygen scavenging capability and can be formed into transparent/translucent thin films are disclosed. A composition can include iron powder, ferrous sulfate heptahydrate (FeSO.sub.4.7H.sub.2O) and glycerol dispersed in polyethylene. Such compositions are useful for creating packaging films with improved oxygen scavenging capability.

A refrigerator is disclosed for improved food storage capability. The refrigerator comprises an internal cavity having a membrane that at least partially covers a portion of the walls of the internal cavity.

A light blocking composite film and preparation method and use thereof. The light blocking composite film comprises a middle non-woven fabric layer, and at least one light-reflective layer and at least one light-absorptive layer alternately arranged on each side of the non-woven fabric layer, wherein the light-reflective layer is made of a resin containing light-reflective particles, and the light-absorptive layer is made of a resin containing light-absorptive particles. The light blocking composite film of the present invention has the advantages of good blocking, not easy to curl, good durability, light-weight structure, beautiful color and the like.

An information security paper is provided. The information security paper includes a first paper layer, a second paper layer, a sensing unit, and a plastic reinforcement layer. The sensing unit and the plastic reinforcement layer are both disposed between the first paper layer and the second paper layer, and the plastic reinforcement layer is located at one side of the sensing unit.

A household appliance liner includes a first polymeric capping layer and a polymeric base layer. The first polymeric capping layer includes a first pigment additive. The polymeric base layer is coupled to the first polymeric capping layer. The polymeric base layer includes one or more polymers, a second pigment additive, and a natural fiber. The natural fiber can be present at a concentration of at least 50% by weight of the polymeric base layer. Methods of producing the household appliance liner are also disclosed.

An ultra-fast marine-biodegradable composite film can include at least one water-soluble layer, and at least one marine-biodegradable layer disposed in contact with the at least one water-soluble layer. The composite film can include a plurality of the water-soluble layer, and a plurality of the marine-biodegradable layer interspaced between the marine-biodegradable layers. The composite film may be used for packaging, including food packaging. Methods of preparing an ultra-fast marine-biodegradable composite film are also disclosed.

A thermal insulating surface structure of a cushion for automobiles and motorcycles is provided. The thermal insulating surface structure includes a main body layer. The main body layer is formed from a polyvinyl chloride resin composition. The polyvinyl chloride resin composition includes polyvinyl chloride and a metal complex. Based on a total weight of the polyvinyl chloride resin composition being 100 wt %, an amount of the metal complex ranges from 3 wt % to 20 wt %.

A protective fabric which includes at least one structural layer and a ceramic composite material layer fixed to the at least one structural layer, is provided. The structural layer can include a non-woven material made from or containing synthetic fibers. The ceramic composite material layer is formed of ceramic composite material powder which includes a ceramic carrier, and iron-silver crystals containing zero-valent iron and zero-valent silver supported on the ceramic carrier. The protective fabric is effective for removing VOCs, suppressing bacterial growth, and filtering or inactivating virus, such as SARS-CoV-2 virus. Protective products or articles incorporating the protective fabric are also provided.
