It has crystal-like transparency, light transmittance above 92%, soft light, clear vision, and acrylic colored with dyes has a good color development effect. Acrylic packaging bottles have excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance.
Acrylic sheets have good processing properties, and can be thermoformed or mechanically processed. Transparent acrylic sheet has a light transmittance comparable to glass, but the density is only half that of glass. In addition, it is not as fragile as glass, and even if it is broken, it will not form sharp fragments like glass. The abrasion resistance of acrylic sheet is close to that of aluminum, and it has good stability and resistance to various chemicals. Acrylic packaging bottles have good printability and sprayability. The use of appropriate printing and spraying processes can give acrylic products an ideal surface decoration effect. Flammability: It is not spontaneously combustible but is flammable and does not have self-extinguishing property.
Hardness is one of the parameters that best reflects the production process and technology of cast acrylic packaging bottles, 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. 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 for cast plates: tolerance = ± (0.4 + 0.1 x thickness); tolerance requirements for extruded plates: tolerance = <3 mm thickness: ± 10 %> 3 mm thickness: ± 5 %; transparency/whiteness: strict The selection of raw materials, advanced formula follow-up and modern production technology ensure the excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.
