The characteristics of Cosmetic Acrylic bottles , hardness is one of the parameters that can best reflect the production process and technology of cast acrylic sheets, and it 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 plate will shrink and bend and whether the surface will crack during processing. Hardness is one of the hardness indicators for judging the quality of acrylic sheets, and the average Da Rockwell 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 casting plate tolerance requirements: tolerance = ± (0.4 + 0.1 x thickness) extrusion plate tolerance requirements: tolerance = 3 mm thickness: ± 5% 3, raw materials with strict transparency/whiteness Matching, advanced formula follow-up and modern production technology ensure excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.

With crystal-like transparency, the light transmittance is above 92%, the light is soft, the vision is clear, and the acrylic colored with dyes has a good color development effect. Acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high-temperature performance. Acrylic sheets have good processing properties and can be either thermoformed or mechanically processed. A transparent acrylic sheet has light transmittance comparable to glass, but the density is only half of the glass. In addition, it is not as brittle as glass, and even if broken, it will not form sharp shards like glass. The wear resistance of acrylic sheets is close to that of aluminum, with good stability and corrosion resistance to various chemicals. Acrylic sheets have good printability and sprayability, and proper printing and spraying processes can give acrylic products an ideal surface decoration effect. Flame resistance: It is not self-igniting but is flammable, and does not have self-extinguishing properties.
