Different Points Between Extruded Acrylic Sheet & Cast Acrylic Sheet
Extruded acrylic sheet and Cast acrylic sheet are all belongs to acrylic products. But there is still some different points because of the difference production menthod. Detailled different points between Extruded acrylic sheet and Cast acrylic sheet as follows:
1. Transparency :Cast acrylic sheet transparency is more than 98%, while the Extruded acrylic sheet is only around 92%
2. Property :Cast acrylic sheet has high molecular weight, excellent stiffness, strength and excellent chemical resistance. This feature is suitable for small quantity processing, there are unmatched flexibility in color and surface texture, and complete product specifications for a variety of special purposes.
Compared with the Cast acrylic sheet, the extrusion acrylic sheet has low molecular weight, weaker mechanical properties. However, this feature is conducive to bending and thermoforming process, fast plastic vacuum forming in dealing with the larger size sheet,.

3. Tolerance :Extruded acrylic sheet thickness tolerances is lower than cast acrylic sheet. Extrusion acrylic sheets is crowded high-volume automated production, the tolerances can be controlled at ± 0.1mm. Cast acrylic sheet tolerances is increasing based on the thickness (check the acrylic sheet tolerance chart), and the Extrusion
4. Color & thickness : the Extruded acrylic sheet color adjustment is inconvenience because of the big extrusion machine, so the product is limited by a certain color,normally only keep the clear color , also the thickness normally is under 8mm because of the extrusion technology. The cast acrylic is easy to make any color.

5. Exterior : Cast acrylic sheet is very transparent without dotting . For the Extruded acrylic sheet will be squeezed edge dotting. For the B-level board can see the edge is yellow and dark. For the A-level panel edge also seems a little dark.
6. SIZE : Extruded acrylic sheet will choose 1.83M * 1.22M and 2.44M * 1.22M, the width is notmally around 1.22m . While Cast acrylic sheet length and width can be customer chosen , (but not too wide, this will cause deformation and big tolerance, check on the cast acrylic specifation chart).
7. APPLICATION : EXTRUSION ACRYLIC sheet is normally used for LED products , light guide panel , diffuse panel and someplace need the small tolerance sheets. Cast acrylic sheet is used for the handcraft products or the bathroom, with the varity thickness and color. For the other place , both is ok.
