Solid polycarbonate sheet, like hollow polycarbonate sheet, has many different colors. Common colors are transparent, green, blue, milky white, brown and so on. Customers who use more will find that the colors of solid polycarbonate sheet produced by different manufacturers are actually the same, with large deviations.
Why does the color of some solid polycarbonate sheet look uneven, the surface is gray, and it feels dirty?
In fact, the uneven color of the solid polycarbonate sheet is mainly due to the following reasons:
1. The manufacturer chooses low-quality or recycled polycarbonate as the raw material for the solid polycarbonate sheet. The solid pc sheet is made of low-quality polycarbonate, which looks blurry or has some small spots, resulting in uneven color of the solid polycarbonate sheet;
2.The color masterbatch of solid polycarbonate sheet is unevenly dispersed during the extrusion process. The color masterbatch distribution of the PC solid sheet is not good during extrusion molding, which causes the endurance board extrusion port to show stripes;
3. Poor stability of polycarbonate sheets or masterbatch. In order to make the sheet have a uniform color, the manufacturer must strictly control the production conditions, and pay attention to the temperature, material and production cycle during the production process;
4. The shape and extrusion method of the solid polycarbonate sheet will also cause uneven color of the solid polycarbonate sheet. Sometimes, the shape or position of the PC solid sheet has a certain influence on the filling of the board, causing local color difference of the sheet;
5.The cooling rate of each part of the extruder is different. When extruding colored solid polycarbonate sheets, the cooling rate of each part of the machine should be as consistent as possible.
Therefore, the key to the color difference of PC solid sheet is to choose a formal and reliable large-scale endurance board manufacturer.
