How to distinguish between different types of sheet materials?
Currently, there are many plastic sheets that are reasonably sought after in the market, and plastic sheets represent a very broad industry. The popular plastic sheets in the market include acrylic sheets, PC sheets, and PS sheets, which are all very similar, especially the transparent sheets. How can we compare these sheets?
First: Acrylic (PMMA) can be divided into: extruded sheets and cast sheets. The identification of extruded sheets is that they have good transparency, and the initial identification method involves burning; when burned, the flame is clear, there is no smoke, there are bubbles, and it can produce long threads. The identification of cast sheets is that they have even higher transparency, when burned, there is no smoke, there are bubbles, and a sizzling sound, and they do not produce threads when heated.
Second: PC sheets, the identification method is: high transparency, good impact resistance, unbreakable, and when burned, they do not catch fire easily, are flame-retardant, and may emit some black smoke.
Third: PS organic sheets, the identification method is: average transparency, and they appear to have speckles when reflecting light. They are more brittle and prone to cracking. When dropped on the ground, they make a cracking sound. When burned, they produce significant black smoke.
