Why use PC material as a dining table for high-speed rail/aircraft?

PC board performance:

1. Impact strength: The impact resistance of PC solid sheet is high, which is 250 times higher than that of traditional glass and 30 times higher than that of acrylic sheet. The impact strength of PC solid sheet is like “transparent steel plate”.
2. Good tensile strength, good heat resistance of PC solid sheet, even at 120℃, its tensile strength can still reach 350kgf/cm2. 3. Bending strength: PC solid sheet has good bending resistance, even if the bending angle reaches 90°, it will not break.
3. Creep resistance: The creep resistance of PC solid sheet is the best among thermoplastics. Creep is small even at high temperatures.
4. The surface hardness can reach 3H–4H
   (2) Thermal performance
5. Melting temperature: The melting temperature of PC solid sheet is 135℃, and its continuous use temperature reaches 120℃.
6. Linear expansion coefficient: The linear expansion coefficient is 7×10-5cm/cm/℃, which is relatively small in plastics.
7. Embrittlement temperature: The embrittlement temperature of PC solid sheet is -40°C, and the maximum continuous use temperature is -30°C, which is incomparable with general plastics. 4. Combustibility: PC solid sheet is one of the flame-retardant and self-extinguishing plastics. It does not produce toxic gases when heated at high temperatures.
8. Thermal conductivity: The thermal conductivity of PC solid sheet is not much different from that of general plastics. It is 1/4 of glass, 1/300 of iron, 1/1000 of aluminum and 1/2000 of copper. It is a material with excellent thermal insulation properties. one. 6. Light weight: the specific gravity is only half of that of glass, saving the cost of transportation, handling, installation and supporting the frame.
9. Flame retardant: The national standard GB50222-95 confirms that the PC board is a flame retardant grade 1, that is, B1 grade. The ignition point of the PC board is 580 degrees Celsius, and it will self-extinguish after leaving the fire. It will not produce toxic gas when burning, and will not contribute to the spread of the fire. Temperature adaptability: PC board will not be cold and brittle at -100 degrees Celsius, will not soften at 135 degrees Celsius, and its mechanics and mechanical properties will not change significantly in harsh environment

So choose PC to make the table board. At the same time can be produced with table-board-heavy-gauge-thermoforming-machine!
