1. Hardness
Hardness is one of the parameters that can best reflect the production process and technology of cast acrylic panels, and is an important part of quality control. The hardness can reflect the purity of the raw material PMMA, the weather resistance of the plate and the high temperature resistance. The hardness directly affects whether the sheet will shrink and bend, and whether the surface will crack or the like during processing. Hardness is one of the indicators for judging the quality of acrylic boards, and the average Mohs hardness value is about 8 or 9 degrees.
2. Thickness (acrylic tolerance)
Acrylic sheet thickness has acrylic tolerance, so the control of acrylic tolerance is an important manifestation of quality management and production technology. Acrylic production has an international standard ISO7823
Tolerance requirements of pouring board: Tolerance = ± (0.4 + 0.1 x thickness)
Tolerance requirements for extruded sheet: tolerance = <3 mm thickness: ± 10%> 3 mm thickness: ± 5%
3. Transparency / Whiteness
Strict raw material matching and selection, advanced formula follow-up and modern production process production ensure the excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.
