Heat Ray Absorption grade
The SD POLYCA™ HA Series is a grade of polycarbonate that retains the high transparency and impact strength inherent to polycarbonate resin, while efficiently blocking heat rays (near-infrared rays). By balancing transparency with heat ray-cutting performance, this material is ideal for use in applications such as carport roofs, terrace roofing, and windows for special vehicles, allowing for natural light while suppressing the rise in indoor or in-vehicle temperatures caused by hot sunlight during summer.
This series provides a practical solution for environments that require both light transmission and heat control, making it particularly suitable for applications where maintaining a cooler interior is essential.
