Whether the acrylic is formed by cast or extruded methods. The product is derivated from a chemical compound. Poly (methyl methacrylate) for short is PMMA. They were used as a close substitution for glass, with a lighter weight of up to 50% and better transparency.

The liquid material mixture is poured into a glass mold to form Cast Acrylic. Casting is more intensive, resulting in a higher price. The properties of cast acrylic are harder, sturdier, and more homogenous products. Casting acrylic stability is better than the extruded ones, making it the perfect choice for fragrances, lotions, or other solvents.

At Jinbao, we provide over 200 colors that you can pick from cast acrylic is more pliable than extruded. And is less prone to bend, chip, or melt during milling. Furthermore, extruded materials have limitations in thickness. Thus, cast acrylic is a better choice for large construction and installation.

Extrusion is a continuous manufacturing production method. Where acrylic monomers are heated and then fed through the barrels, in this step, a chemical process occurs. Thus, extruded acrylic is heterogeneous with properties that vary depending on the direction of the extrusion process.

Extruded acrylic costs less than cast is more dimensionally stable, meaning the thickness is more consistent. The extruded acrylic is much softer and has a lower melting point compared with cast acrylic. But it is easy to laser cut, rout, and polish, which is more cost-effective.

Both extruded and cast acrylics could be polished. To solve problems like scratches and to extend the durability of acrylic sheets. Find out more on the maintenance of acrylics.

Extruded acrylic is less responsive to dirt, lint, or particle contamination in the process of production. In addition, due to the lowering melting point, it is a suitable choice for cementing and thermoforming.
