TPU Film for Automotive Paint Protection Film (PPF)
TPU Film for Automotive Paint Protection Film (PPF)
Overview
TPU (Thermoplastic Polyurethane) film is widely recognized as the core substrate for premium automotive paint protection films (PPF). Its superior flexibility, optical clarity, self-healing, and weather resistance make it the ideal material to protect vehicle surfaces from scratches, stone chips, UV exposure, and environmental damage.
Key Features
-
Excellent optical clarity and gloss retention
-
Self-healing when exposed to heat or sunlight
-
Outstanding scratch, impact, and abrasion resistance
-
Superior UV resistance and anti-yellowing performance
-
High flexibility for complex car body curves
-
Hydrophobic, stain-resistant, and easy to clean surface (after coating)
Application Process
Huanlong supplies stable-quality aliphatic TPU base film for PPF applications. The film is coated with hard coating, adhesive, and liner by converters and OEMs to produce the finished paint protection film used on car exteriors.
Comparison: TPU vs. PVC vs. PET for PPF
| Property | TPU Film | PVC Film | PET Film |
|---|---|---|---|
| Clarity & Gloss | Excellent | Good | Good |
| Self-Healing | Excellent (heat) | None | None |
| Flexibility | Excellent | Low | Moderate |
| Weather Resistance | Excellent (non-yellowing) | Poor (yellowing) | Moderate (yellowing) |
| Abrasion Resistance | Excellent | Good | Moderate |
| Environmental Impact | Recyclable, plasticizer-free | Contains plasticizers | Recyclable |
| Comfort & Aesthetic | Soft-touch, smooth | Hard, less aesthetic | Hard, less aesthetic |
Conclusion
TPU film is the industry-preferred substrate for automotive PPF, offering unmatched self-healing, clarity, flexibility, and long-term weather resistance compared to traditional PVC or PET films.
