TPU (thermoplastic polyurethane) material PPF (paint protection film) has become the preferred choice for high-end car clothing due to its unique self-healing and thermal repair properties.
Self healing performance
Principle: Màng TPU PPF molecular chains undergo displacement when subjected to external forces. When the temperature reaches 40 ℃ or above (such as exposure to sunlight or wiping with warm water), the molecular chains rearrange and the scratches automatically disappear
Repair ability: Can repair scratches with a width of ≤ 0.2mm, repair minor scratches in 3 seconds at room temperature, and repair deeper damage at high temperature
Technological upgrade: Some brands (such as HERZI) have improved repair efficiency to 98% through honeycomb microstructure and thermosensitive polymer coating
Thermal repair performance
Condition: Requires an environment of 40-60 ℃ (such as exposure to sunlight or hot water rinsing), with repair time ranging from a few minutes to several hours.
Durability: High quality TPU film with anti UV formula ensures that the repair ability does not significantly decrease within 5 years
