1. Very high-wear resistance, seven times wear resistance than steel, four times than PTFE.2. Very high-inadhesion resistance, the surface of product hardly affixes other material.3. Good low temperature resistance, in liquefied nitrogen (- 196), it still has the prolongation.4. Non-toxic and clean property, UHMW-PE, which is the material that Food and Drug Administration (FDA) and United States Department of Agriculture (ASDA) permit to apply in food and medicine fields.5.

For yours the big paint chips missing is probably more what would cause me to not consider this. That and the white paint probably act as a higher contrast. I'd think the crack on mine is one 6th or 8th the length of yours total. Once I got it off the car and cleaned it actually went pretty smoothly soldering it, I did practice on some spare plastic first but it didn't take long will I was moving along fairly quickly. Still think doing a longer section like on yours would have only added about an hour of time to prep and solder. However if you were going to then sand and paint, probably need a bit more time to go over it all again on the outside to fill in the outer crack prior to sanding.
The bumper will usually have printed on it somewhere what material it is, often part of the mold itself so inside will have raised marking, in my case PP signifying polypropylene which seems common for bumpers. In my case, I had a spare body part for a different car that was PP too, so I shaved off strips from it to use. You can also just buy sticks of it which are meant for even more specialized soldering tips. Search for "plastic welding rod" on amazon or elsewhere and they're available in a variety of materials. For example this listing has ABS, PP, PVC, and PE.
