Material Difference for Car Paint Protection Film

March 10th ,2019

There are many different materials for car paint masks, but the most common ones on the market are only two: PVC and TPU.

1.PVC material

PVC is what we commonly call polyvinyl chloride, which is simply the same material as the plastic bags we use to shop in supermarkets. PVC film is generally thick, poor weather resistance, hard and embrittlement at low temperature, easy to soften and relax at high temperature; After the auxiliaries are precipitated, the film surface absorbs dust and affects the light transmission. Not only has limited protection for automotive paint, but also the glue remains on the paint when it is removed, damaging the original car paint.

2.TPU material

TPU, is called thermoplastic polyurethane elastomer, single particle structure, physical properties, chemical stability is excellent, with excellent high tension, high tension, toughness and aging resistance characteristics, is a mature environmental protection material, the paint mask of this material can be used for up to 5 years or more.

Among them, polycaprolactone TPU has the best performance, good comprehensive performance, excellent mechanical strength, oil resistance, chemical resistance, wear resistance and tear strength, good flexibility, superior low temperature performance, and there is no ester group that is relatively easy to hydrolysis, and good hydrolysis resistance. Aliphatic TPU has high brightness, good elasticity, more stable, and does not change color or yellow under ultraviolet irradiation.
