NachTek paint protection Film factory frequently Asked Questions

Product-Related Questions

Q1: What materials are NachTek TPU PPF products made of? Are they environmentally friendly?
A1: All NachTek TPU PPF products are made of 100% high-quality TPU (polyurethane) raw materials from well-known global suppliers such as BASF and Covestro. The products have passed EU REACH and RoHS certifications, do not contain harmful substances such as heavy metals and phthalates, and are safe and environmentally friendly, complying with global environmental protection standards.

Q2: What is the difference between 6.5mil, 8mil and 10mil PPF? How to choose the right thickness?
A2: The main difference lies in the protection strength and thickness: 6.5mil is suitable for daily light protection needs, with good flexibility and easy installation; 8mil is the most popular specification, balancing protection performance and installation experience, suitable for most passenger cars; 10mil has super wear resistance and impact resistance, suitable for off-road vehicles or areas with harsh road conditions. We recommend choosing according to your target market's usage scenarios and customer needs.

Q3: Do your PPF products have self-healing function? How does the self-healing work?

Minor scratches (depth ≤ 0.03mm) and marks can be automatically repaired within 3-5 minutes at room temperature (25℃) or under sunlight. The principle is that the special polymer material in the coating has thermal responsiveness, which can restore the surface flatness when heated.

After verification, if it is confirmed to be a product quality problem, we will provide solutions such as free replacement, return and refund, or compensation, depending on the actual situation, to protect the legitimate rights and interests of our customers. A real-world example: In 2023, a North American customer received a bulk shipment of matte paint protection film and found that 10 rolls had frayed edges, affecting installation and use. The customer immediately contacted our after-sales team via WhatsApp and sent photos of the product problem and the batch number. After verifying the relevant information, our after-sales team confirmed that it was an accidental quality issue during the slitting process.  That same day, we provided the customer with a solution: we would send them 10 rolls of brand-new products free of charge and cover the shipping costs for the replacement.  We also offered an unconditional return for the 10 defective rolls, and we covered the return shipping costs as well. Ultimately, the replacement products were delivered to the customer within 5 business days, and the entire problem resolution process took only 8 business days.
