Liquid ingredients mix in glass molds to form Cast Acrylic. Casting is more labor intensive, making it more expensive. Casting yields a harder, sturdier, and more homogenous product. Casting lends greater chemical resistance over extrusion, making it the preferred material for uses involving fragrance, lotions, or other solvents. Available in a broad range of standard and custom colors for a variety of applications, cast acrylic is more pliable than extruded, less likely to bend, chip, or melt during milling. Because extruded material is limited in thickness, cast acrylic is a better option for larger structures, installations, etc.
