Main Classifications Of Acrylic Sheets

Acrylic casting board: high molecular weight, excellent rigidity, strength, and excellent chemical resistance. The characteristics of this type of board are small batch processing, unparalleled flexibility in color system and surface texture effect, and complete product specifications, suitable for various special purposes.
Acrylic extruded sheet: Compared with cast sheet, extruded sheet has a lower molecular weight and slightly weaker mechanical properties. However, this feature is beneficial for bending and thermoforming processing, and is advantageous for rapid vacuum forming when dealing with large-sized sheets. Meanwhile, the thickness tolerance of extruded plates is smaller than that of cast plates. Due to the large-scale automated production of extruded boards, it is inconvenient to adjust colors and specifications, which limits the diversity of product specifications.
Acrylic board materials are mainly classified into three categories in China: first, imported boards; The second is the Taiwan funded board; The third is domestically produced boards. Their difference lies in the origin of the raw materials used and the purity of MMA. This is also the key to determining the quality and price of the board.
There are two brands of acrylic sheets imported domestically: Mitsubishi (Mitsubishi Chemical) from Japan and Degussa from Germany.
The so-called Taiwan funded board refers to a board made from pure MMA raw materials from the UK and Taiwan's technology and processes. Most of the molds used for producing sheet metal are made in the UK and Germany. The produced acrylic sheets have uniform color, no water marks, and small thickness errors;
Domestic board refers to the raw materials used in the production of boards, which are either domestically produced or produced through secondary processing of recycled materials (PMMA) from various acrylic boards. But the disadvantage is that the surface has obvious water marks, uneven thickness, and is prone to yellowing. It is not suitable for vacuum forming and is only suitable for carving. The advantage is the low price. After experimental verification on a tablet machine. The spraying effect has a certain gap compared to the imported one.
