Acura Bumper Material and Bumper Repair

Polyurethane (PUR), Reaction Injection Molding (RIM), Reinforced reaction injection molding (RRIM), Thermoset polyurethane — Most common on domestic vehicles. Yellow or grey in color. Bubbles and smokes when you attempt to melt. Thermo-set PUR sands powdery and can be smoothed with a grinder as long as you don’t use high pressure or high speed that causes the plastic to liquefy.

PUR and most thermo-set plastics are repaired by heat fusing and grinding a “V” groove and filling with urethane filler material and structural support (stainless steel screen) to the backside of the cracked material.

Thermoplastic Olefin (TPO), Thermo-Elastic Olefin (TEO)— TPO and TEO are a combination of polypropylene, an elastomer or rubber, and a mineral filler such as calcium carbonate or talc.

TPO bumper material sands in chunks melts like butter with high-speed grinders, feels like wax and gets stringy when hot, so keep this in mind when trying sand or grind a TPO bumper cover.

TPO bumper covers are the most difficult to repair because they contain 3% to 5% wax-based mold release within the material. The embedded wax makes it difficult for filler, adhesive, primer and paint to stick. Body shops prefer to discard a TPO bumper because the repair is so difficult

However, TPO IS repairable as long as you know how to prepare it. You must use a cleaner and adhesion promoter prior to adding any filler material.

Thermoplastic Poly Propylene— PP is semi-flexible, melts & smears when grinding, waxy or greasy feel. Repaired by heat fusing and grinding a “V” groove and filling with polypropylene filler material and structural support (stainless steel screen) to the backside of the cracked material.
