Durability Comparison of Steel Plate Protective Films
1. Material Types
PET Protective Film
Stable chemical properties with strong anti-aging and UV resistance. Maintains clarity without yellowing/brittleness. High surface hardness (excellent scratch resistance).
Modified PE Film
Enhanced with antioxidants/UV absorbers for improved weather resistance. Performs well in extreme temperature variations.
PVC Protective Film
Cost-effective but less durable. May release harmful substances at high temperatures. Not recommended for long-term use.
2. Process & Structure
• Special coatings (hardening/antistatic) improve wear resistance
• Multi-layer composites (PET+adhesive+scratch-resistant layer) enhance tear resistance
• Surface treatments determine dustproof effectiveness
• Multi-layer composites (PET+adhesive+scratch-resistant layer) enhance tear resistance
• Surface treatments determine dustproof effectiveness
3. Key Performance Metrics
Temperature Range: -30℃ to 80℃ without softening/brittleness
UV Protection: ≥40 UV factor for outdoor applications
Adhesion: 1kg load at 60℃ for 24h without detachment
4. Recommended Options
PET Fluorine Film
Fluorine coating provides ≥3H hardness. Superior weather resistance for outdoor protection (5+ years).
Thickened Anti-aging PE
>0.15mm thickness with additives for 2-3 year durability. Cost-effective with clean removal.
