In daily life, we can see all kinds of acrylic products everywhere, such as acrylic photo frames, acrylic display stands, etc. So what are the characteristics of acrylic products? Let me take you to understand it below.
One: 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 the cast plate: tolerance=±(0.4 + 0.1 x thickness)
Tolerance requirements of the extruded board: Tolerance=<3mm Thickness: ±10%> 3 mm Thickness: ±5%
Two: Transparency/Whiteness
Strict raw material selection, advanced formula follow-up and modern production technology production ensure excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.
Three: Hardness
Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheets, 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 crack during processing. Hardness is one of the hard indexes for judging the quality of acrylic sheet, and the average Dallow's hardness value is about 8 or 9 degrees.
The above are the main features of acrylic products, I hope it can help everyone.
