Repairing Polypropylene,
TEO and TPO bumpers

These plastics are known as "thermoplastics". Thermoplastic parts are created by melting plastic and then injecting that melted plastic into the mold. After the plastic cools and resolidifies, the part can be removed from the mold.

Repairing these bumpers is very easy using the steps outlined in "The Book" of automotive plastic repair.
