invisible car clothing is made of thermoplastic polyurethane film

the material of the invisible car cover is thermoplastic polyurethane film (tpu).

thermoplastic polyurethane film is an (ab) n-type block linear polymer, a is a high molecular weight (1000~6000) polyester or polyether, b is a glycol containing 2~12 linear carbon atoms, ab the chemical structure between the segments is diisocyanate.

thermoplastic polyurethane rubber is cross-linked by hydrogen bonds between molecules or light cross-linking between macromolecular chains. as the temperature increases or decreases, these two cross-linked structures are reversible. in the molten state or solution state, the intermolecular forces weaken, but after cooling or the solvent evaporates, strong intermolecular forces connect them together, restoring the original solid properties. typical tpu such as spandex, etc.

features:

1. excellent ductility and super tensile strength; can be pasted on any arc surface.

2. anti-yellowing for more than 3 years and anti-aging for more than 5 years.

3. crystal-like transparency, integrated with the original car, without affecting the original color of the car paint; it can increase the gloss of the car paint by 5%-20%.

4. it can resist damage to the paint surface caused by oil, grease, weak alkali, sand, acid rain, etc.

5. super softness and memory, can resist general scratches and friction.

6. good uv resistance to prevent long-term damage to the car paint; protect the gloss of the original car paint.

7. good adhesiveness, no edges opening or cracking.

8. good pressure-sensitive adhesive properties ensure that it can be removed at any time without leaving any residual adhesive.

9. comply with environmental protection requirements.

10. the surface protective film is a transparent pe with a thickness of 3 wires, which can ensure that the base material will not be scratched during construction and can be stretched with the base material.
