[Object] To provide a building material having excellent durability.

[Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.

A multi-layer packaging film structure is disclosed. This packaging film structure includes a barrier web made up of a barrier web core layer, a barrier web skin layer, and a packaging sealant layer. Each of the aforementioned film layers is biodegradable and/or compostable. At least one of the film layers is made up of at least 1 weight percent of poly(3-hydroxypropionate). The packaging film structure may also include a print web or a paperboard substrate.

A film for laminating glass includes a polyvinyl acetal, a plasticizer, inorganic particles, and a trioxane-based compound.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

Described herein are fire hoses incorporating new combinations of materials to increase the hose's resilience. Resilient hoses include those made with silicone-coated fabrics or with thermally-resistant fabrics or both.

A polishing article includes a polishing layer having a working surface including at least one multi-cell structure disposed on the working surface. The multi-cell structure includes three cells, defined as a first cell, a second cell and a third cell. Each of the three cells includes at least one sidewall defining a cell shape. The first cell and the second cell include a first common sidewall including a first channel, having a first channel length, allowing fluid communication between the first cell and the second cell, and a first axis perpendicular to the first channel length and substantially parallel to the working surface. Further, the second cell and the third cell include a second common sidewall including a second channel, having a second channel length, allowing fluid communication between the second cell and the third cell, and a second axis perpendicular to the second channel length and substantially parallel to the working surface. An included angle between the first axis and the second axis is from 0° to less than 180°.
