1. PMMA (acrylic) organic glass
Divided into extruded plates and cast plates, the identification of extruded plates is the transparency number. Using the most primitive identification method, the fire is burning, the flame is clear when burning, there is no smoke, there is air bubbles, and the filament can be drawn when the fire is extinguished.
The identification of the cast board is: higher transparency, no smoke, bubbles, squeaking sound when burning with fire, and no wire when extinguishing.
2. PC endurance board
The identification method is: high transparency, good impact resistance, not broken, burning with fire is basically not burning, flame retardant and will emit some black smoke.
3. PS organic board
PS organic board, the identification method is: the transparency is normal, there will be pitting when it is reflected.
It is brittle and easy to break. It will make a clicking sound when it hits the ground, and it will produce a lot of black smoke when burned with fire.
4. MS board
The identification method is: the transparency is normal, there will be pitting when it is reflected, and a large amount of black smoke will be produced when burning with fire.
It is basically close to PS board, but its flexibility and processing performance are better than PS board organic board.
