What are the differences between acrylic extruded and cast sheet?

We can know that acrylic sheet includes two types: acrylic casting sheet and acrylic extruded sheet. Acrylic cast sheets are produced by melting acrylic raw materials at high temperature and placing them in a mold. Acrylic extruded sheet is generally made by first melting the acrylic raw material, and then extruding it at high temperature through mechanical equipment. What are the differences between these two sheets manufactured by different production methods?

What are the advantages and disadvantages of acrylic casting panels?

Advantages of acrylic cast sheet:

①Pouring acrylic sheet has excellent rigidity. ("Rigidity" refers to the ability of a material or structure to resist elastic deformation when subjected to a force. The popular understanding is the ability of a material to resist external forces and maintain its original shape.)

② The chemical resistance of the acrylic cast sheet is excellent.

③ The specifications of the acrylic pouring sheet are very complete.

④ The acrylic cast sheet has very good transparency.

⑤ Acrylic cast sheet has unparalleled flexibility in color and surface texture.

Disadvantages of acrylic cast sheet

① Because it is cast, the thickness of the sheet has a large error (for example, a 20mm thick sheet may actually be only 18mm thick).

② A large amount of water is needed for cooling in the process of casting production, which is easy to produce industrial sewage and cause pollution to the environment.

③ The size of the entire sheet is fixed, and the flexibility of producing other specifications of sheets is poor, which is likely to cause waste of sheet scraps and increase the unit price of the product.

What are the advantages and disadvantages of acrylic extruded panels?

Advantages of acrylic extruded sheet:

① The thickness tolerance of acrylic extruded sheet is small.

② Acrylic extruded sheet is suitable for single-variety and mass production.

③The length of the plate can be adjusted, which can produce long plates.

④ Sheets are easy to bend and thermoform. When processing larger sheets, it is helpful for quick plastic vacuum forming.

⑤ Mass production of acrylic extruded sheets can reduce production costs, and has great advantages in production dimensions.

Disadvantages of acrylic extruded sheet

①The molecular weight of acrylic extruded sheet is low, and the mechanical properties are slightly weaker.

② Since the acrylic extruded sheet is mass-produced automatically, it is inconvenient to adjust the color, so the product is subject to certain color restrictions.

③ Cast board and extruded sheet belong to a kind of acrylic sheet, and the color of the sheet is similar (the common ones on the market are white, red, blue, green, etc.).

What are the differences between the two sheets?

The differences between acrylic cast sheet and acrylic extruded sheet:

1. The transparency of the acrylic cast sheet is above 98%, while the transparency of the acrylic extruded sheet is only above 92%.

2. There are no pits on the edge of the acrylic cast sheet, and the edge is very transparent; there will be pits on the edge of the acrylic extruded sheet, and the edge of the B-level board of the extruded sheet can be seen yellow and black, and the edge of the A-level sheet of the extruded sheet It will be darker.
