Acrylic sheet features
Aug 25, 2018
1. Thickness Acrylic Tolerance: Acrylic sheet thickness has acrylic tolerance, so the control of acrylic tolerance is an important embodiment of quality management and production technology. Acrylic production has an international standard ISO7823 casting plate tolerance requirements: tolerance = ± (0.4 + 0.1 x thickness) tolerance requirements for extruded plates: tolerance = < 3 mm thickness: ± 10% > 3 mm thickness: ± 5% 3. Transparency/Whiteness: Strict raw material selection, advanced formula follow-up and modern production process ensure excellent transparency and whiteness of the board. After the flame is polished, it is crystal clear.
2. Hardness: Hardness is one of the parameters that best reflects the production process and technology of casting 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, and the average Dalhou hardness value is about 89 degrees.
