The acrylic sheet is divided into a casting plate and a pressing plate according to the production process, and can be divided into a transparent plate and a translucent plate (including a transparent plate of the dyeing plate) according to the transmittance; the impact plate, the anti-UV plate and the color plate are classified according to the performance (including Black and white and color board), ordinary board and special board such as high impact board, flame retardant board, frosted board, metal effect board, high wear board, light guide board, etc.
A: Casting plate: high molecular weight, excellent stiffness, strength and excellent chemical resistance. Therefore, it is more suitable for processing large-sized signboards, which is relatively long in the softening process. This sheet is characterized by small batch processing, incomparable flexibility in color system and surface texture effects, and complete product specifications for a variety of special applications.
B: Extrusion plate: Compared with the cast plate, the extruded plate has a lower molecular weight, a slightly weaker mechanical property and a higher flexibility. However, this feature facilitates bending and thermoforming processes with a shorter softening time. When dealing with larger sheets, it is advantageous for a variety of rapid vacuum forming. At the same time, the thickness tolerance of the extruded plate is smaller than that of the cast plate. Since the extrusion plate is mass-produced in an automated manner, color and specifications are inconvenient to be conditioned, so the product specification diversity is limited.
