This infrared light shielding laminate includes: an ITO particle-containing layer; and an overcoat layer which covers an upper surface of the ITO particle-containing layer, wherein core shell particles are present in a state of being in contact with each other in the ITO particle-containing layer, and the core shell particle includes an ITO particle serving as a core and an insulating material serving as a shell that covers the core.

A reinforced insulation assembly is disclosed. The assembly includes insulation, a reinforcement layer, and an adhesive for attaching the reinforcement layer to a surface of the insulation. The reinforced layer is fully immersed within the adhesive and penetrates the surface of the insulation.

Described in this disclosure is a surface configured to break down deposits thereon. The surface may include breakdown structures, oleophilic structures, and hydrophilic structures. The oleophilic structures and hydrophilic structures are configured to disperse a deposit, such as fingerprint residue, to the breakdown structures. This dispersion increases the surface area of the deposit with respect to the breakdown structures, increasing the contact area between the two. The breakdown structures modify the deposit physically, chemically, or both, such that fragments are distributed into the ambient environment. The surface may be applied to portable electronic devices.

The invention discloses a high performance plastic magnetic material, comprising a low surface energy layer, a magnetic layer and a printable layer, wherein the magnetic layer and the printable layer are arranged successively on a first side of the low surface energy layer; the low surface energy layer is an organic silicon pressure sensitive adhesive layer. The invention further discloses a preparation method, comprising the following steps: pretreating a magnetic powder with a coupling agent; mixing the pretreated magnetic powder with matrix components and auxiliaries to gain a mixture; extrusion compositing the gained mixture with a printable layer to gain composite paper having the printable layer and a magnetic layer; and applying a low surface energy layer on a side of the magnetic layer, opposite the printable layer. As no UV layer and no adhesive residue, the material of the invention is environmentally friendly and highly reliable.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
