Window Profiles

Calcium/Zinc Stabilizers (Ca/Zn) are commonly used in PVC window profiles as a safe and more sustainable alternative to lead-based systems. They provide excellent thermal stability, UV resistance, and color retention—key properties for exterior applications. Our Ca/Zn stabilizers are compatible with modern extrusion processes and help ensure a smooth surface and long-lasting performance. Their use supports compliance with international environmental standards such as RoHS and REACH, making them a preferred choice in many markets.
