C endurance board (also known as polycarbonate solid board, PC bulletproof glass, PC solid board, polycarbonate board) is made of high-performance engineering plastics - polycarbonate (PC). Application: advertising road signs, light box advertisements, telephone booths, exhibitions, sound insulation screens of highways and elevated roads, agricultural greenhouses, ceilings, etc.
PC solid sheet has the following characteristics
Impact resistance: The impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic sheets of the same thickness, and 2-20 times that of tempered glass.
Light transmittance: The light transmittance of solid board can reach up to 89%, which can be beautiful with glass.
Flame retardancy: The national standard GB50222-95 confirms that the solid board is a flame retardant grade 1, that is, B1 grade. The ignition point of the PC board is 580 ℃, and it will self-extinguish after leaving the fire.
Bendability: It can be cold-formed and installed into arches, semi-circular roofs and windows. The minimum bending radius is 175 times the thickness of the plate, and it can also be hot bent.
Weather resistance: PC board does not become cold and brittle at -40 °C, and does not soften at 125 °C. The surface UV agent (anti-ultraviolet) has the ability to absorb ultraviolet rays and convert them into visible light, which can guarantee ten years of colorfastness outdoors.
