In turn, it is very resistive, making in almost armored. It may be bendy at times so we leave a safe margin of thickness to achieve a desired arrow of bending.
An interesting property of acrylic is its thermoinsulation and relatively low melting point (110 degrees celsius). It is also easy in grinding, polishing and milling, possessing good mechanical modifications possibilities.
