Acrylic, also known as PMMA or plexiglass, is derived from English acrylic (acrylic plastic) and its chemical name is polymethyl methacrylate.
It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance. It is widely used in the construction industry. Plexiglass products are generally classified into cast sheets, extruded sheets, and molding compounds.
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 sheet will shrink and bend, and whether the surface will be cracked during processing. Hardness is one of the hard and good indicators for judging the quality of acrylic sheets. The average Mohs hardness is about 8 or 9 degrees.
2. Thickness (acrylic tolerance)
Acrylic sheet thickness has acrylic tolerances, so the control of acrylic tolerance is an important manifestation of quality management and production technology.
3. Transparency / whiteness
Strict raw material selection, advanced formulation follow-up and modern production processes ensure excellent transparency and whiteness. After the flame is polished, it is crystal clear.
Acrylic sheet is divided into 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); , anti-UV board, ordinary board and special board such as high impact board, flame retardant board, frosted board, metal effect board, high wear board, light guide board, etc.
Acrylic is the best new material that can be used to make sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic has the following advantages in addition to unparalleled high brightness: good toughness and not easy to break; strong repairability, just use a soft foam to remove the toothpaste to wipe the sanitary ware; soft texture, winter There is no sense of cold and biting; the color is bright, which can satisfy the individual pursuit of different tastes. Acrylic basins, bathtubs and toilets are made of acrylic, which are not only beautiful in style, durable, but also environmentally friendly. Their radiation levels are similar to those of the human body.
