摘要: The invention is a foam blend comprising polyethylene, polypropylene, and rubber component. has improved flexibility at sub-zero temperatures without sacrificing the desirable physical characteristics that are commonly associated with polypropylene foams. As result, particularly useful for producing articles require approaching below 0° F. In some embodiments, may have least 50 percent by weight up to about 45 polyethylene. component in be from 3 10 percent, 5 being useful. blends suitable variety of where it cold temperatures. application, used concrete expansion joint fillers or totes.
