1. The acrylic sheet is divided into the casting board and extrusion board according to the production process. According to the transmittance, it can be divided into transparent board, translucent board (including transparent board of dyeing board), color board (including black and white and color board); Impact plate, anti-ultraviolet plate, ordinary plate and special plate…
1, hardness Hardness is one of the parameters that best reflects the production process and technology of the acrylic sheet, and is an important part of quality control. The hardness can reflect the purity of the raw material PMMA, the weather resistance of the sheet, and the high-temperature resistance. The hardness directly affects whether the…
Pp plastic molding, pp is an engineering material with excellent comprehensive performance, its material performance density is small, strength stiffness, hardness and heat resistance are better than low-pressure polyethylene, with good electrical properties and high-frequency insulation are not affected by humidity However, it becomes brittle at low temperature, does not wear and is easy to…
