Hi Rene, bumpers are made of: >PP< polypropylene, TPO (THERMOPLASTIC OLEFINE),TPU (THERMOPLASTIC URETHANE,PU (POLYURETHANE)ALL OF THEM INJECTION MOLDED. And carbon fiber, glass fiber (tuning bumpers hand-made)to identify look in the back or invisible side  as installed, for a marking code. something like >tpu< or S.A.E code TPU.
