Infrared (IR) reflective pigments are innovative solutions designed to address the bending problems in PVC window profiles caused by heat build-up. These issues arise due to the lower glass transition temperature (Tg) of PVC, which can lead to thermal deformation under intense sunlight.

Key Features and Benefits:

• Reduction in Heat Build-Up: IR reflective pigments reflect a significant portion of near-infrared radiation, reducing the surface temperature of PVC profiles even under direct sunlight. This minimizes the risk of thermal expansion and bending.

• Enhanced Dimensional Stability: By maintaining a lower surface temperature, these pigments help PVC profiles retain their shape and structural integrity over time, ensuring long-lasting performance.

• Improved Weather Resistance: IR reflective pigments also enhance the overall durability of PVC window profiles, protecting them against UV-induced degradation, fading, and chalking.

• Aesthetic Flexibility: These pigments are available in a wide range of colors, enabling manufacturers to produce visually appealing profiles without compromising thermal performance.
