There has been a lot of talk about paint protection film, and now we should all know that to buy paint protection film, you should choose TPU material. TPU material is the most effective paint protection film material developed on the basis of PVC, TPH and other materials.
It is mainly divided into polyester type and polyether type, with a wide range of hardness (60ha-85hd), wear resistance, corrosion resistance, transparency and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields.
The paint protection film made of this material has excellent abrasion resistance, friction resistance, crushed stone sand erosion resistance and scratch resistance, good tensile and tensile properties greatly facilitate the construction needs, low initial viscosity and high holding viscosity are also very suitable for repeated construction.
However, this material can distinguish between high and low, and can be divided into aliphatic TPU and aromatic TPU, and has undergone a completely new change. At the beginning of TPU, due to technical limitations, the density of the topcoat was insufficient, and it was difficult to resist external invasion, and the yellowing phenomenon has always existed.
The second-generation TPU learned from the experience of the former, and on the basis of its research, the TPU matrix material was molecularly cross-linked, and the top coating was improved, using a nanoscale of less than 0.0001 millimeters.
It can improve the resistance to the invasion of foreign objects in almost all daily life environments, and ensure that the invisible car clothing remains clean and shiny for a long time.
TPU, plastic polyurethane, several types of polyurethane.
TPU (plastic polyurethane) has more repair ability than PU, and plastic polyurethane is divided into thermoplastic polyurethane (thermal repair ability) and self-plastic polyurethane (second repair ability).
At present, only the Nar PPF brand invisible car clothing on the market has developed a real meaning of second repair, and the difference between PU and TPU is that PU car clothing does not have the ability to automatically repair scratches.
