What are OEM bumpers made of?!

I am contemplating on buying an M3 replica bumper for my 335i and saw vendors that sold them in polypropylene and polyurethane. Both claiming it is the same material as OEM.

Ok, I have gone through the search and google for this question.

I have read threads and sites where they claim that oem bumpers are made of polypropylene, and then I came across sites that claim they are made of polyurethane.

So my question is:


Thanks =)

I always thought OEM bumpers were made from ABS plastic.

However I can tell you that polypropylene is a great alternative. My front bumper as well as my sideskirts are both made out of it and I couldn't be happier after dealing with so many fiberglass parts over the years. Avoid fiberglass, it cracks easily because it's so rigid. Polypropylene feels like OEM and it's sturdy, strong, and flexible.

it would be either polypropylene or urethane.
