Acrylic sheetAlso known as polymethyl methacrylate (PMMA) sheet plexiglass, is a special process of plexiglass, acrylic sheet research and development, dating back more than one hundred years of history, in the past few years, acrylic sheet also entered the interior decoration of the house, so what are the advantages and disadvantages of acrylic sheet?
1. Hardness
The hardness of acrylic sheet is one of the important parameters that can well reflect the production process and technology, and it is also a part of quality control. The hardness can reflect the purity of raw material MMA, the weather resistance and high temperature resistance of the sheet. Hardness can directly determine whether the plate will shrink, bend and deform, and whether the surface will crack during processing. Hardness is one of the hardness indexes to judge the quality of acrylic plate. Imported cast acrylic plate has a higher hardness index of the same products in China, with an average Dallowell hardness value of about 89 degrees.
2. Thickness tolerance
What does thickness tolerance mean? That is to sayAcrylic sheetThe thickness of acrylic tolerance, the control of this tolerance is an important embodiment of quality management and production technology, imported material cast acrylic plate thickness of acrylic tolerance control within 0.2mm.
3. Weather resistance
The adaptability of yake plate is very good, and its adaptability to the natural environment is very strong. Even if it is exposed to sunlight, wind and rain for a long time, its performance will not change. It has good anti-aging performance and can be used outdoors with peace of mind.
4. Transparency
Strict selection of raw materials, advanced formula follow-up and modern production process. Ensure good transparency and pure whiteness of the plate, and crystal clear after flame polishing.
Of course,Acrylic sheetAlso has its shortcomings, acrylic sheet because the hardness is relatively low. Therefore, the heat resistance will be relatively poor, and then the elongation will be relatively low, which will lead to easy fragmentation and deformation. Then there is the color is not stable enough, in the use of the process is prone to fluffing phenomenon.
