What is Leidu 8.5mil PCU PPF

Our 8.5mil PCU paint protection film is made of polycarbonate urethane, a high-performance PCDL system polyurethane material. Different from common aliphatic TPU, this formula focuses on resisting hydrolysis and yellowing under long-term UV, heat and chemical exposure. The glossy transparent layer keeps the original paint color bright while providing full surface protection for cars. It is widely stocked by film shops, distributors and export wholesalers.

PCU vs Regular Aliphatic TPU PPF

Both PCU and aliphatic TPU belong to polyurethane paint protection film. The core difference lies in the raw material system.
PCU uses PCDL (polycarbonate diol) as raw material, which has better molecular stability. It performs much better in anti-hydrolysis and anti-yellowing, especially in high-temperature, rainy and coastal humid areas.
Ordinary aliphatic TPU is cost-effective and stable in mild climates, but its aging speed will accelerate under continuous hot and humid conditions.
If your target market is tropical, coastal or high UV regions, PCU PPF is a better long-term choice for your customers.
