What is TPU Film?
TPU (Thermoplastic Polyurethane) PPF is a high-performance automotive paint protection film made from thermoplastic polyurethane elastomer rubber. It provides full-coverage physical protection for the original paint, combining defense, aesthetics, and functionality, making it a mainstream choice in the automotive detailing industry.
Core Features and Advantages
Outstanding Physical Protection
TPU material offers high toughness, abrasion resistance, and impact resistance, effectively shielding against daily scratches, stone chips, and other external damage to prevent damage to the original paint. With a tensile strength exceeding 50 MPa, it can tightly conform to complex body curves, ensuring seamless protection.Self-Healing Capability
Equipped with heat-sensitive molecular chain technology, the TPU film can automatically repair minor scratches (e.g., from car washing towels) when exposed to sunlight or warm water (above 40°C), with scratches typically disappearing within 10-20 minutes. This feature significantly extends the film’s lifespan.Weather Resistance and Stability
TPU base material exhibits excellent UV resistance, anti-yellowing, and chemical corrosion resistance, maintaining clarity and gloss even after long-term use. High-quality products, enhanced with antioxidants, ensure the self-healing function remains effective for up to 5 years.Environmental Friendliness and Installation Adaptability
TPU is recyclable and eco-friendly. Its high elongation (over 400%) supports custom data cutting for a perfect fit, with edges remaining tight and nearly invisible after installation.
Comparison with Other Materials
- VS PVC/TPH: Traditional PVC is prone to yellowing, cracking, and lacks self-healing, while TPH, an improved version of PVC, still falls short of TPU performance.
- VS PET: PET material is hard but lacks elasticity, making it unable to wrap complex curves effectively, resulting in limited protection.
Purchasing Tips
- Choose Aliphatic TPU: Opt for aliphatic-based (not aromatic) TPU, which has a denser molecular structure for superior hydrolysis and yellowing resistance.
- Focus on Coating Technology: Multi-layer coatings (e.g., nano-hydrophobic layers) enhance stain resistance, corrosion protection, and self-cleaning.
- Select Reputable Channels: Ensure products are factory-authorized to avoid low-quality materials masquerading as TPU, which could compromise performance.
