4mm transparent Makrolon polycarbonate panels imported from Bayer board PC board Features 1, light transmittance: good light. Solid sheet of light transmission rate up to 88%. 2, weather resistance: The surface layer co-extruded UV, can block sunlight ultraviolet rays pass through, thus the plate not aging yellow, with good weather resistance. 3, noise performance: good insulation properties, can effectively reduce the noise, highway sound barrier material of choice. 4. Impact: the impact strength of PC sheet is 250-300 times of the same thickness of ordinary glass, 30 times that of acrylic plates, glass 2 times, there is "no broken glass" reputation, is to create high-quality bullet-proof glass material . 5, flame retardant: GB GB8624-2006 test is a flame retardant B1 level, does not produce toxic gases when burned from the fire self-extinguishing, does not contribute to the spread of fire. 6, temperature: minus 40 degrees Celsius to 120 degrees Celsius, will not be deformed, mechanics and mechanical properties change significantly, such as quality degradation phenomena; 7. Portability: light weight, polycarbonate panels are generally only half the density of glass, thus saving transportation, moving unloading, installation, and the cost of the support frame and sheet can be cold, giving the architects a wider design space.
