Light blue transparent polycarbonate (PC) sheet is a high-performance thermoplastic engineering plastic. It is widely used in modern industry, construction, automobile, medical and consumer electronics due to its excellent optical transparency, excellent impact strength, weather resistance and chemical resistance.
Polycarbonate (PC) is a polymer material synthesized by bisphenol A (BPA) and diphenyl carbonate (DPC) through polycondensation reaction. Its molecular chain contains aromatic ring structure, which gives the material high rigidity, high toughness and excellent thermal stability. Light blue transparent PC sheet is given a soft light blue appearance while maintaining high light transmittance by adding light scattering agents (such as TiO₂ or organic dyes), which has both aesthetic value and functionality.
The light transmittance of the sheet can reach 85%-90% (depending on thickness and additive formula), which is close to glass (92%), but the weight is only 1/2 of glass, the impact strength is 200-300 times that of ordinary glass, and it has self-extinguishing properties (UL94 V-0 fire rating), making it an ideal material to replace glass.
Product performance
Optical performance:
Light transmittance: 85%~90% (depending on thickness), light blue tint can filter some ultraviolet rays and glare, providing comfortable visual effects.
Low haze (<1%) ensures clear light transmission, suitable for applications with high optical quality requirements.
Mechanical properties:
Impact strength is 200 times that of ordinary glass and 30 times that of acrylic sheet, which can effectively prevent shattering
Bending strength ≥90 MPa, good rigidity, can withstand a certain load.
Thermal performance:
Temperature resistance range: -40℃ ~ +120℃, short-term resistance to 140℃, not easy to deform at high temperature.
Heat deformation temperature (HDT) ≥130℃ (1.82 MPa load).
Weather resistance:
UV-resistant coating (optional), effectively blocks 99% of ultraviolet rays (UV400), no yellowing or brittleness after long-term use.
Meets ISO 4892-2 aging test standard, outdoor service life of more than 10 years.
Chemical stability:
Resistant to weak acids, weak bases, greases and alcohol, but not resistant to strong bases and some organic solvents (such as acetone).
Flame retardancy:
Complies with UL94 V-0/V-2 standards (optional flame retardant grade), oxygen index ≥25%, self-extinguishing when away from fire.
Lightweight:
Density 1.2 g/cm³, only half the weight of glass, easy to transport and install.
Scope of application

Transportation:
High-speed rail/subway window shields, bus station anti-collision baffles.
Ship windows, aircraft interior translucent parts (must meet aviation standards).
Industrial protection:
Equipment observation windows, mechanical protective covers, explosion-proof mirrors.
Clean room panels, laboratory partitions (anti-chemical corrosion).
Special applications:
Translucent parts of medical equipment (such as X-ray protection screens).
Agricultural greenhouses (optimizing blue light bands to promote plant growth)
Conclusion
Light blue transparent PC sheet has an irreplaceable position in many industries due to its high light transmittance, ultra-high impact resistance, excellent chemical resistance and weather resistance, lightweight and processability. Its aesthetic and functional characteristics (light blue tone) further expand its application scenarios, from architectural lighting to medical equipment, from automotive lighting to electronic housing, all showing excellent performance.
