What is sunshine board?

Sunshine board is the general name of the polycarbonate hollow board, also called the PC sun board, Capron board, etc., which is processed and produced from high-performance engineering plastic polycarbonate resin. It has high transparency, lightweight, impact resistance, The characteristics of sound insulation, isolation thermique, ignifuge, anti-aging, easy processing, etc. are a kind of high-tech, comprehensive performance of the best energy-saving and environmentally friendly plastic sheet of all plastic sheets.
Polycarbonate hollow solar panel is an industrial engineering plastic with excellent comprehensive performance. It has outstanding physical, mechanical, electrical, and thermal properties; therefore, it is known as the "King of Plastics" and has good impact resistance, isolation thermique, and sound insulation. Daylighting, protection UV, natural resistance, etc. It has a wide range of uses and is currently the most ideal industrial engineering plastic board material in the world.
traits: lightweight, impact resistance, sound insulation, easy processing
Widely used in: building roof lighting, railway station high-speed rail ceiling, airport hangar ceiling, shelf display partition, server partition, stadium swimming pool roof, corridor ceiling security protection
Color classification: W white, BU color, T brown, G green, R red absolutely, Y yellow, B bright, O orange, others can be customized
Polycarbonate (PC for short) is a molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, and aliphatic aromatics.


The name of the polycarbonate, the English name of Polycarbonate, is also known as PC plastic. The chemical formula is 2,2'-bis(4-hydroxyphenyl) propane polycarbonate. Polycarbonate is a tough thermoplastic resin whose name comes from its internal CO3 base
group. Can be synthesized by bisphenol A and carbon oxychloride (COCI2). The most commonly used method is melt transesterification (bisphenol A and diphenyl carbonate are synthesized through transesterification and polycondensation). Reaction principle of bisphenol A and diphenyl carbonate: polycarbonate
Ester is an almost colorless glassy amorphous polymer with good optical properties. PC molecular weight resin has high toughness, the Izod notch impact strength is 600~900J/m, and the heat distortion temperature of unfilled grades is about 130°C. After glass fiber reinforcement, this value can be increased by 10°C.
The flexural modulus of the sunshine board can reach more than 2400MPa, and the resin can be processed into large rigid products.
Main advantages:
1. It has high strength and elasticity coefficient, high impact strength, and wide temperature range;
2. High transparency and free dyeability;
3. Low forming shrinkage and good dimensional stability;
4. Bonne résistance aux intempéries;
5. Excellent electrical characteristics;
6. Tasteless and odorless, harmless to the human body, in line with hygiene and safety.
Main performance
a. Mechanical properties: high strength, fatigue resistance, dimensional stability, and small creep (very few changes under high-temperature conditions);
b. Heat aging resistance: the enhanced UL temperature index reaches 120~140°C (long-term outdoor aging is also very good);
C. Solvent resistance: no stress cracking;
e. Electrical performance: 1. Insulation performance: excellent (it can maintain stable electrical performance even under humidity and high temperature, it is an ideal material for manufacturing electronic and gas parts); 2. Dielectric coefficient: 3.0-3.2; 3. Arc resistance: 120s; f, molding processability: ordinary equipment injection molding or extrusion.
