Casted plexiglass tubes have better properties and parameters than extruded tubes. How are they made? The production of casted plexiglass tubes differs considerably from how extruded tubes are produced. Consequently, their physical properties are different as well. Casted tubes are made through the polymerising of PMMA and cooling it down. This process allows us to select any colour, length or thickness of our casted tubes. Also, it takes more time to produce casted tubes than extruded ones. The production process of the former does not go as smoothly as the production of the latter. As a result, casted tubes are more expensive than extruded ones.
Casted tubes can be used at slightly higher temperatures (up to 80 degrees Celsius) than extruded ones. Also, casted tubes are easier to machine mechanically, which is of great significance. They have better tension and compression parameters, thanks to which it is safe to make various kinds of cuts and holes in them. In order to do so, we need to use tools and power tools with fine teeth, and the tubes have to be placed horizontally on a hard basis. Unlike extruded plexiglass items, casted plexiglass objects can be etched into with a laser. What is more, casted tubes are by far more resistant to scratching and injurious chemicals. Plexiglass plates make perfect shop windows as well as roofs of car parks, garages, carports, terraces and winter gardens. Plexiglass objects are fully transparent; they allow over 90% of light to pass through them, and they do not turn yellow with time, which enables us to install them outdoors.
