8.5 mil thickness series

The 8.5-mil thickness series represents the mid-to-high-end product line of DCL automotive transparent films, with a thickness of 8.5 mils (approximately 0.216 mm), offering an optimal balance between protective performance, application ease, and cost.

Material Properties and Protective Performance

The 8.5mil thick series employs aliphatic TPU substrate, which contains no benzene rings and has a density several times higher than aromatic TPU, providing superior protection. For basic protection, the 8.5mil thick body cover withstands 120J impact with only a 0.3mm dent and can endure impacts from 8mil gravel. Field tests on the Sichuan-Tibet Highway showed that after being struck by gravel, the white mark depth remained ≤0.5mm, demonstrating the product's "mobile fortress" durability. Regarding self-repair capability, the 8.5mil thick series utilizes thermal repair technology: after 1,000 scratches, it achieves a 92% recovery rate under 60°C hot air, with key scratch depth reduced by 80%.

Adaptability to special environments is a standout feature of the 8.5 mil thickness series. It maintains flexibility at 15°C, shows no rust spots after 720 hours of salt spray exposure, and demonstrates 28% enhanced UV resistance under敦煌-style intense sunlight. With tensile strength ≥15 MPa and elongation>400%, its peel strength reaches 700 N/m at room temperature after 72 hours, remaining stable after thermal aging, water immersion, and QUV accelerated aging tests. The puncture resistance improves by 37% compared to the 7.5 mil thickness variant, saving approximately ¥4,300 in paint repainting costs over five years.
