Microporous material

Microporous materials that include thermoplastic organic polyolefin polymer (e.g., ultrahigh molecular weight polyolefin, such as polyethylene), particulate filler (e.g., precipitated silica), and a network of interconnecting pores, are described. The microporous materials of the present invention possess controlled volatile material transfer properties. The microporous materials can have a density of at least 0.8 g/cm.sup.3; and a volatile material transfer rate, from the volatile material contact surface to the vapor release surface of the microporous material, of from 0.04 to 0.6 mg/(hour*cm.sup.2). In addition, when volatile material is transferred from the volatile material contact surface to the vapor release surface, the vapor release surface is substantially free of volatile material in liquid form.

20200368798 · 2020-11-26 ·

A metal sheet having a low friction coefficient and a low waviness. Multiple round or roughly-round small pits are distributed on the surface of the metal sheet. The diameter of a single pit ranges from 30 m to 150 m, and the overlap between adjacent pits is lower than 10%. On the surface of the metal sheet where the pits are located, the proportion of the area of pits per square millimeter of surface area is greater than 30%, and the difference between the quantities of pits in any unit square millimeter is less than 20%. By means of the proper design of surface microstructure, the friction coefficient and the waviness can be effectively reduced, thereby improving the forming and painting performance of the material.
