The reason why PVC door and window profiles have become the mainstream choice in modern architecture and stand out from many materials is their excellent comprehensive performance. Especially in dealing with impacts and ensuring long-term safety, PVC impact modifiers play a very important role.

Especially in low-temperature environments, its brittleness is more pronounced. If unmodified PVC is directly used for door and window profiles, a strong wind carrying debris or accidental collisions in daily life may cause them to crack or even break. The addition of PVC impact modifier fundamentally changes the microstructure of PVC.

And in the PVC melt processing, the addition of PVC impact modifier helps to improve the melt strength and flowability of the material, making the extrusion process more stable.

So PVC impact modifiers have laid a solid foundation for the excellent air tightness, impact resistance, and other aesthetic aspects of the final doors and windows.
