How does the composite sheet distinguish between acrylic and PC?
Do not know what you said PC is what, acrylic, well recognized ah, take a lighter, get one or two acrylic point, and burn nothing is acrylic, understand?
Nearly 90%, the naked eye is not easy to distinguish. But the two are, after all, two kinds of materials, the difference is four different:
Heat resistance, temperature, weather resistance: acrylic plate to 70 degrees easy to soften, and PC is 120 degrees, so PC more temperature and heat, working temperature wider application.
Impact resistance, resistance to drop, resistance to strength indicators: the same thickness, PC impact resistance is 30-50 times the acrylic plate, 6 mm start PC thick plate is bulletproof material, 3 mm PC board ordinary adult with a hammer also smashed not broken.
Flame retardant: PC is a flame retardant material, belonging to the B-class flame retardant (international UL94-V2 level), one of self-extinguishing plastic, not easy to burn, while the acrylic plate is not flame retardant.
Environmental protection: PC is environmentally friendly plastic, and some physical properties of the acrylic board can not reach, so some areas have been out of acrylic acrylic applications, the country will gradually spread, although China is the acrylic board power, but the production of high value-added acrylic sheet Rarely, are dependent on imports.
Find a small sample, nail nails, nails full density, easy to brittle is the acrylic, anti-stress burst is a good point of PC, PET the strongest.
Recommended under the new, times the special strength of the board, and acrylic (PMMA) than the impact of strong 30 times, not brittle, easy to transport processing. Compared with the PC, the performance is quite, but the toughness is stronger, not stress cracking, fracture and solvent melting, the price is cheaper. 3mm thickness of domestic PET engineering sheet made of domestic factories rarely, we are one of them. You need to be able to communicate under the words, contact the way in my / household / name.
