PC sheets precisely achieve “blocking ultraviolet rays while allowing visible light,” thanks to the wavelength-selective filtering of polycarbonate molecules.

Filtering Logic: Ultraviolet rays (wavelength 100-400nm) have extremely high energy and can directly damage the molecular chains of plastics. PC sheets, through a UV co-extruded coating, utilize ultraviolet absorbers to convert these high-energy rays into micro-heat, dissipating them with a blocking rate of over 99%.

Visible light (wavelength 400-700nm), required for plant photosynthesis, has lower energy and a longer wavelength. The PC molecular structure is almost “transparent” to this wavelength range, allowing approximately 82%-92% of visible light to pass through, ensuring plants receive sufficient “photosynthetic food.”

Greenhouse Value: This “light-heat separation” characteristic not only protects plants from scorching ultraviolet rays but also utilizes the greenhouse effect to lock in long-wave infrared rays (heat energy), achieving a cooler indoor environment in summer and a warmer indoor environment in winter.

When installing, please make sure the UV-resistant coating side faces outwards to prevent the board from yellowing from the inside.
