 1. The acrylic acrylic and methacrylic chemicals are meticulotics. Including monomers, sheets, pellets, resins, and composites, acrylic plates are polymerized by methyl alkacoate monomers (MMA), ie polymethyl methacrylate (PMMA) sheet organic glass, "organic Glass is derived from the trade name "OROGLAS" (a PMMA board), which is taken from "Organic Glass" (ie organic glass).

2, the acrylic plate is divided into three major categories according to the material classification: one is imported board; the other is the Taiwan-funded board; the third is domestic board. Their difference is the origin and (mma) purity of the raw materials employed. This is also the key to determining the quality and price of the sheet.

3, acrylic has high transparency, transmitted by 92%, with "plastic crystal". And have excellent weather resistance, especially for outdoor, raw to other plastic crops, and have good surface hardness and gloss, large processing plasticity, can be made into a variety of desired shapes and products. There are a variety of colors of the sheets (including translucent swatches), and the other feature is that the thick plate still maintains high transparency. .

4, hardness is one of the most artificial parameters of the production process and technology of pouring pouring brake board, is an important part of quality control. The hardness can reflect the purity, sheet weather resistance and high temperature resistance of the raw material MMA. The hardness directly affects whether the sheet will shrink the bending deformed, and the surface will occur when the surface is processed. Hardness is one of the quality of the acoustic plate quality. Imported material pouring diaphragms have the current highest hardness indicators in the same product in China. AverageRockwell hardnessThe value is around 89 degrees.

5, PMMA has the advantages of light, cheap, easy to form. Its molding method has cast, shot molding, machining, heat molding, etc. In particular, it is injected, which can be produced in large quantities, simple process, low cost. Therefore, its application is increasingly widely used in instrumentation parts, car lights, optical lenses, transparent pipelines, etc.
