What Are the Differences Between Extruded Acrylic and Cast Acrylic Sheets

Acrylic is a particularly versatile materials which is utilized in a variety of environments. acrylic solid surface sheet factory sheeting is accessible in an enormous vary of variations, together with; clear, colored, mirrored, frosted and even with a brushed aluminium impact.

Extruded acrylic and solid acrylic are the 2 foremost forms of sheet acrylic you’ll come throughout. Though they might initially look comparable, the 2 have fairly completely different properties and one can also be far more costly than the opposite.

You will need to pay attention to the variations between the 2 so you possibly can decide the sort most fitted on your wants.

Extruded and solid acrylic sheets differ primarily of their thermal and chemical properties that are brought on by the manufacturing course of. There are additionally a number of different variations as outlined under which you will want to take into account when selecting acrylic sheet on your dwelling DIY challenge.

Key variations you ought to be conscious of when working with acrylic sheets:

Thickness variations

As a result of means the sheets are made solid acrylic are likely to have slight variations within the thickness of the sheet whereas extruded sheets are far more uniform, with subsequent to no variation. This makes extruded acrylic ultimate for vacuum forming or conditions the place extra detailed exact shapes are wanted.

Temperature response

Solid acrylic has an isotropic response to temperature which means there’s a most shrinkage of two% in all instructions. It could be necessary to notice that acrylic expands and contracts at a a lot larger price than glass. Extruded acrylic, however, exhibits variations in shrinkage relying on the thickness and course of extrusion.

Advantages of Extruded sheets


  • Diminished mechanical properties imply course of benefits over solid acrylic when bending, heating and vacuum forming
  • Higher thickness tolerances
  • Decrease viscosity when scorching means it’s extra ductile than solid acrylic


Advantages of Solid acrylic sheets


  • Higher thermal stability
  • Increased resistance to crazing (when a community of very small cracks type) when uncovered to solvents
  • Wider thermoforming vary than extruded acrylic
  • Higher means to be reworked scorching
  • Superior floor end and optical properties


Each forms of acrylic profit from being sturdy and lengthy lasting, exhibiting glorious resistance to pure ageing. Most manufactures will assure towards noticeable yellowing for roughly 10 years.

Typically it will not be made apparent which kind of acrylic you’re shopping for, particularly on-line. Solid acrylic will be as a lot as double the worth of extruded acrylic so if nothing is talked about and it appears low-cost, the probabilities are it’s extruded acrylic.
