What is a sunshine board?
Sunshine plate It is a general designation of polycarbonate hollow panel, also known as PC sunshine board and Kaplan board. It is made of high-performance engineering plastic polycarbonate resin. It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, fire resistance, aging resistance and easy processing. It is a kind of high-tech, energy-saving and environment-friendly plastic with the best comprehensive performance for all plastic panels at present board.
Polycarbonate hollow Sunshine plate It is a kind of industrial engineering plastic with excellent comprehensive performance, which has outstanding physical, mechanical, electrical and thermal properties. Therefore, it has the reputation of "king of plastics", with good impact resistance, heat insulation, sound insulation, daylighting, ultraviolet protection, and flame resistance, and has a wide range of uses. It is the most ideal industrial engineering plastic plate material in the world.

Polycarbonate (PC) is a kind of polymer with carbonate group in the molecular chain. According to the structure of ester group, PC can be divided into aliphatic, aromatic, aliphatic aromatic and other types.
Polycarbonate, also known as PC plastic, has the chemical formula of 2,2 '- bis (4-hydroxyphenyl) propane polycarbonate. Polycarbonate is a kind of strong and tough thermoplastic resin, and its name comes from its internal CO3 group. It can be synthesized from CoCl2 and CoCl2. The most commonly used method is melt transesterification (Synthesis of bisphenol A and diphenyl carbonate by transesterification and polycondensation). Reaction principle of bisphenol A and diphenyl carbonate: polycarbonate is an almost colorless amorphous polymer in glass state with good optical properties. PC high molecular weight resin has high toughness. The notched impact strength of the cantilever beam is 600 ~ 900j / m. the hot deformation temperature of unfilled grade is about 130 ° C. This value can be increased by 10 ° C after glass fiber reinforcement.
The bending modulus of sunlight board can reach 2400mpa or more, and the resin can be processed into large rigid products.
1. High elastic strength, high temperature and impact strength;
2. High transparency and free staining
3. It has low shrinkage and good dimensional stability;
4. Good weather resistance
5. Excellent electrical characteristics
6. Tasteless and odorless, harmless to human body, in line with health and safety.
A. mechanical properties: high strength, fatigue resistance, dimensional stability and small creep (little change under high temperature conditions);
B. heat aging resistance: the temperature index of UL is 120 ~ 140 ℃ (outdoor long-term aging is also good);
C. solvent resistance: no stress cracking;
E. electrical performance: 1. Insulation performance: excellent (humidity and high temperature can also keep electrical performance stable, which is an ideal material for manufacturing electronic and electrical parts); 2. Dielectric coefficient: 3.0-3.2; 3. Arc resistance: 120s; F. molding processability: ordinary equipment injection molding or extrusion molding.
