Quality Automotive-Grade Foam
3M™ Rigid Pillar Foam is a two-part urethane material which foams in place (closed-cell foam). It can be applied to areas where OEMs recommend rigid foams such as pillars, sills, doors, floor pans, roof bows and other automotive body cavities. Use it wherever OEM rigid foam is found.
Easy to Work into Difficult Places
Our pillar foam is easy to use. It flows in and fills so that all cavities are filled without the need for technicians to work foam into hard-to-reach areas. It just effortlessly flows to fill challenging spots. Once in place, it expands 10 times its original volume to fill large cavities. You only need to use a small amount of material to fill a large area.
Replicates OEM Appearance
Use our foam for OEM replacement of rigid foams, closely mimicking OEM performance. Using our product helps to closely restore to “pre-accident condition”.
