When sourcing pleated (accordion) retractable window screens, distributors often ask: "Should we choose Polyester (PET) or Polypropylene (PP) for pleated screen mesh? What are their differences in UV resistance and lifespan?" As a professional pleated mesh manufacturer, Ji'an Screen Mesh provides a comprehensive breakdown of the three mainstream materials.
1. Comparison of 3 Mainstream Pleated Mesh Materials
| Material Type | Structure & Focus | Advantages & Ideal Applications | Drawbacks & Precautions |
|---|---|---|---|
| 1. Polyester / Coated Mesh | Multi-strand + PVC/Polymer Coating Extreme Durability | Superior UV resistance, long lifespan, compatible with all frame systems. Ideal for balconies with intense western sun exposure. | Slightly thicker wire diameter with minor visual obstruction. |
| 2. PP Mesh | Mono-filament Heat-set High Transparency & Aesthetics | Ultra-clear, superior ventilation, virtually invisible. Ideal for shaded windows and bedrooms requiring maximum airflow. | Sensitive to prolonged intense UV; must be paired with PET monofilament cords to prevent hole expansion and sagging. |
| 3. PET Mesh | Mono-filament Polyester Rigid Texture & Form Retention | High visual clarity with shape-memory recovery after light impacts. | Stiff texture; oversized screens may deform during folding over time, causing friction. |
2. Sourcing FAQ
