TPU PPF
TPU PPF Material Introduction
TPU (Thermoplastic Polyurethane) is a high-performance elastomer combining the flexibility of rubber with the durability of plastics. We exclusively use premium TPU raw materials from global chemical leaders like Lubrizol,BASF and Covestro, ensuring material purity and consistent performance from the source. The molecular structure of TPU delivers exceptional impact resistance, chemical corrosion resistance, and self-healing properties, making it the ideal base material for Paint Protection Film. Compared to traditional PVC or PU films, TPU PPF provides superior anti-yellowing performance, offering long-term protection against UV rays, acid rain, road debris, and other environmental hazards while preserving the original gloss of vehicle paint. We guarantee zero material substitution – every batch is certified under ISO 9001 and validated by third-party laboratories.
Multi-Layer Structure Breakdown
Hydrophobic Nano Topcoat
Patented nano-coating technology achieves a water contact angle >110°, effectively repelling water stains and oil residues for enhanced self-cleaning.
Self-Healing Functional Layer
Proprietary polyurethane self-healing coating automatically repairs micro-scratches (≤30μm) within 24 hours at room temperature; heat activation (60℃) accelerates recovery to 5-10 minutes for flawless surface restoration.
TPU Base Layer
High-purity TPU core with customizable thickness (6-10mil) and tensile strength >35MPa, providing puncture resistance and flexibility to conform seamlessly to complex contours.
Pressure-Sensitive Adhesive
Eco-friendly residue-free adhesive (SGS-certified) with bond strength >200g/25mm ensures secure attachment and clean removal without damaging OEM paint.
Release Liner Backing
Dual-layer protective film maintains adhesive integrity during storage/installation, enabling precision cutting and bubble-free application.
Key Advantages
✅ Self-Healing Technology: Micro-scratches vanish at room temperature; heat accelerates recovery (60℃±5℃).
✅ 10-Year Warranty: Anti-yellowing formula validated for 10+ years of outdoor durability in lab testing.
✅ Optical Clarity: 95%+ light transmission for invisible protection without altering paint texture.
✅ Eco-Friendly: Compliant with RoHS/REACH standards, zero VOC emissions.

-
*Yellowing Resistance (ΔE)**：Measured per ASTM G154 accelerated aging, lower ΔE indicates superior color stability (ΔE≤1.0 = visually undetectable).
-
Self-Healing：Room temperature recovery time noted; * denotes heat-activated acceleration (e.g., ULTRA-10 recovers in 2hrs at 60℃).
-
Mechanical Properties：Tensile strength (MPa) and elongation (%) reflect tear resistance and flexibility – higher values = stronger protection.
Applications
Luxury vehicle full/partial body protection
Motorcycle, yacht, and aircraft surface shielding
Scratch-resistant films for consumer electronics
