PMMA is short for polymethyl methacrylate, which is nontoxic. The temperature at which polymethyl methacrylate starts to flow is about 160℃, and the temperature at which polymethyl methacrylate starts to decompose is higher than 270℃, so it has a wide processing temperature range. Usually, boiled water filled with plexiglass is not enough to reach this temperature, because it is non-toxic under normal circumstances.
Polymethyl methacrylate (PMMA) is an important thermoplastic developed earlier. PMMA can be divided into four types: colorless transparent, colored transparent, pearlescent and embossed PMMA.
Extended data:
First, the aesthetics of plexiglass: mirror effect, exquisite craftsmanship, no wrinkles and no seams;
Second, the visual effect of plexiglass: diverse colors and strong visual impact;
Third, the transmittance of plexiglass: the transmittance can reach 96%, the transmittance is excellent, and the light is soft;
Fourth, the impact resistance of plexiglass: it is more than 200 times that of ordinary glass products, and there is almost no risk of breakage;
5. Durability of plexiglass: the product has good protection for the built-in light source, which prolongs the service life of the light source product;
6. weatherability of plexiglass: it can be stored for a long time without fading, and the service life of good quality plates is as long as 6- 13 years;
7. Flame retardancy of plexiglass: spontaneous combustion and self-extinguishing will not occur;
