1 Answers
The differences between PU and TPU materials for car wraps are as follows: 1. PU: The material used is polyurethane. Compared to PVC material, its advantage is increased toughness; the disadvantages are poor weather resistance, weak resistance to alkaline corrosion, gradual yellowing that cannot be repaired, and poor anti-fouling performance. 2. TPU: The material used is thermoplastic polyurethane. Its advantages include strong impact resistance, puncture resistance, and scratch resistance, stable thermal repair function, strong water repellency, excellent corrosion and stain resistance, high-temperature resistance, as well as low-temperature resistance, oil resistance, chemical resistance, etc. This material is recyclable and belongs to environmentally friendly materials. The disadvantage is complex processing and higher price.
