It is disclosed a plastic foam product having and exhibiting excellent temperature resistance, tear resistance, and flexibility properties produced from a blend comprising poly-1-butene, styrenic block copolymer, and/or an olefinic rubber, and optionally a non-elastomeric polyolefin. These foams are particularly useful in very high temperature applications such as pipe wrap in refrigerators and HVAC.
