Besides the obvious difference between the base polymer, what is the difference bewtween polyolefin foams and polyurethane foams? In looking at the differences, the processing and therefore cost, appear different. If using as an air seal are there major difference to be aware of? All of my research leads me to believe that they wuld perform the same (at the same density). Thanks!
