(A) mechanical properties
1. Impact strength: PC resistance plate impact resistance is excellent, its impact resistance is 250 times the same thickness of glass, is 30 times the acrylic sheet.
The impact strength of the Pc endurance plate has the name "transparent steel plate".
2. Tensile strength is good, PC resistance plate heat resistance is good, even at 120 ℃, its tensile strength can still reach 350kgf/cm2.
3. Bending strength: PC resistance plate bending resistance is good, even if the bending angle of 90 °, still does not break.
4. Fatigue and creep resistance: PC resistance to creep in the thermoplastic is the best. Even at high temperatures, its creep is still very small.

(B) thermal properties
1. The melting temperature: PC resistance plate melting temperature 135 ℃, the continuous use of temperature up to 120 ℃.,
2. Coefficient of linear expansion: coefficient of linear expansion of 7 × 10-5cm / cm / ℃ in the plastic is small.
3. Mbrittlement temperature: PC brittle board temperature of -40 ℃, the minimum continuous use temperature of -30 ℃, is the general plastic incomparable.
4. Combustibility: PC endurance board is one of the flame-retardant self-extinguishing plastic, which does not produce toxic gases when heated at high temperatures.

(D) sound insulation
The sound insulation effect of PC resistant panel is 3-4DB higher than that of glass
Sunlight panel is the trade name of polycarbonate transparent panel, referred to as PC panel, which is a new decorative material with high strength, light transmission, sound insulation and energy saving commonly used internationally. It has excellent performance of light weight, weather resistance, super strength, flame retardant and sound insulation, and is widely recognized by architectural design, decoration engineering, environmental engineering and advertising industry. The sales volume of sunlight panels in the international market is growing at a rate of 20% per year. With the gradual upgrading of domestic buildings, a number of key national construction projects have taken the lead in adopting sunlight panels, which has accumulated valuable experience in design, construction and daily maintenance for the promotion of this material in China.
