Why PPF be Self-Healing?


It is not all the PPF material are self-healing, but only TPU PPF, self-healing is a kind of material property.

TPU, thermoplastic polyurethanes, with excellent elasticity, elongation at break is above 50%, is a kind of polymer plastic material with good elastic recovery performance when external force withdrawing.

TPU PPF car paint film will be broken when suffer external force. TPU polymer material will be breaking elongating when external force withdrawing. High Temperature will accelerate and speed up the breaking elongation, to realize self-healing.

We POLYSAN supply excellent TPU PPF, TPU thermoplastic polyurethane elastomer from Lubrizol SMM301 base material, good self-healing, anti-yellowing.
