The present disclosure provides a low gloss sheet and a matte product prepared therefrom. The low gloss sheet includes a substrate and a low gloss layer disposed thereon. The low gloss layer includes polyester and a matting agent. A weight percentage of the matting agent is 4 wt % to 10 wt % based on the total weight of the low gloss layer. The matting agent includes a plurality of first particles and a plurality of second particles. An average particle diameter (d.sub.50) of the first particles and the second particles is 8 to 10 m and 3 to 6 m respectively. An oil absorption of the second particles is 30 to 100 ml/100 g. The matte product is prepared from the low gloss sheet by a forming technique.

A prefabricated tile-type coating, whose manufacture is based on the development of a polymeric composite including mainly recycled synthetic rubber obtained from the grinding of scrap automotive waste tires, virgin rubber, or a combination of both, using as a binder a novel cross-linkable acrylic resin with the ability to be processed by pultrusion. The upper layer of the tile is made of a resin with thermochromic effect that integrates an encapsulated pigment of thermochromic material with a transition temperature in the range of 20-35 C. which changes color from white under high-temperature conditions, i.e. C. or greater than dark in conditions of low temperature, that is, 20 C. or less. The tile of elastomeric character obtained has notable competitive advantages compared to other technologies in terms of thermal resistance, solar reflectance, and resistance to the impact caused by hail or other meteorological phenomena.

A packaging material film according to the present disclosure includes a first resin layer that contains a polyolefin resin and a porous filler. A ratio Y/X of an average particle size Y m of the porous filler to a thickness X m of the first resin layer is 0.02 to 3.5, and a content percentage of the porous filler in the first resin layer is 0.5 to 30 mass %. A packaging material according to the present disclosure includes a substrate and a packaging material film disposed on the substrate. In the packaging material, the packaging material film is formed of the above packaging material film, and a surface of the first resin layer of the packaging material film on a side opposite from the substrate is exposed.

Provided is a piezoelectric film capable of suppressing a decrease in sound pressure even in a case of long-term use or repeated use and having high durability. The piezoelectric film is a piezoelectric film including a piezoelectric layer consisting of a polymer-based piezoelectric composite material that contains piezoelectric particles in a matrix containing a polymer material, and electrode layers formed on both surfaces of the piezoelectric layer, in which a skewness Rsk of a roughness curve of at least one surface of the piezoelectric layer is in a range of 3.5 to 5.
