Name: PC, also known as: polycarbonate commonly known as: bullet-proof glass / shatterproof glass manufacturer: Gaelic German company sheet: thickness (10 ~ 50 mm) * width 600/500 mm * 1,000 mm long bars: ￠ 10 ~ ￠ 200 mm * 1000 mm Usage: In aviation, electronics, machinery industry, has been used as windshields, bulletproof glass, instrument of observation windows, wiring board governance, models. Features: low crystallinity polymer plastic, with a wide temperature range and super high impact, with toughness, creep resistance, mechanical strength and dimensional stability, with transparency, ductility, resistance to climate and temperature, for -150 to +120 ℃. Flame resistant to radiation resistance, good insulation, hard bold, good electrical insulation. Disadvantages: sensitive to the dent, stress, cracking of the gap on the hydrolysis reaction, chemical resistance is poor, prone to scratches, easy to polish and difficult long-term water immersion resistance arc dissolved in hydrogen chloride will be brittle / cracked by the erosion of aromatic keto acids .
