Acrylic (loanword)

Characteristics

1.Hardness

Hardness is more reflective of the cast acrylic sheet production process and technology, one of the parameters, is an important part of quality control. Hardness can reflect the raw material PMMA purity, sheet weathering and high temperature resistance. Hardness directly affects whether the sheet will shrink and bend and deform, whether the surface will chafe when processing, etc.. Hardness is one of the hardness indicators to judge the quality of acrylic sheet.

2. Thickness (acrylic tolerance)

Acrylic sheet thickness there is an acrylic tolerance, so the control of acrylic tolerance is an important embodiment of quality management and production technology. Acrylic production have an international standard ISO7823

Tolerance requirements for casting plate: tolerance = ± (0.4 + 0.1 x thickness)

Extruded sheet tolerance requirements: tolerance = < 3 mm thickness: ± 10 % > 3 mm thickness: ± 5 %.

3.Transparency/Whiteness

Strict selection of raw materials, advanced formula follow-up and modern production processes ensure the transparency and pure whiteness of the sheets. Flame polished and crystal clear.
