How is acrylic glass made?

The basic chemical production of acrylic glass is complicated and not important to the user - apart from the properties of acrylic glass. However, the further processing of the "raw material", from which acrylic glass is produced in the last steps, is of crucial importance in the choice of acrylic glass, which in individual cases must meet all desired requirements.

Acrylic glass manufacturing process

The price of acrylic glass has a marked difference between rolled and cast PMMA. Often the cheaper, rolled acrylic glass is equated with a lower grade quality. But that's not easy to explain. It is the individual requirements that determine whether rolled or cast acrylic is to be used.

Differences in longevity in temperature

The difference in longevity is particularly serious in boats and yachts, whose components are like acrylic glass hatches: boats and yachts are often on the move in warmer regions (Mediterranean, for example). At moorings in warmer regions, the longevity of cast acrylic is well above that of extruded acrylic, as there are rapid cracks.

Heat treatment (forming, bending) of acrylic glass

If you want to bend or shape colored acrylic glass (after heating), the rolled PMMA is more suitable because of its heterogeneous properties (cast acrylic is homogeneous). When cast acrylic glass, which is bent or deformed, the homogeneous structure must be abandoned. Therefore, colored acrylic that is cast may explicitly experience slight changes in color (in the bent or deformed area).
