    摘要: A cellular thermoplastic polyolefin foam comprising at least one particulate additive in admixture with a polymer matrix is disclosed, along with a process and foamable gel for manufacturing the same, wherein the polyolefin matrix comprises at least one polymer resin graft-modified with at least one polar group selected from the group consisting of acid, acid ester, and acid anhydride, and salts thereof. The invention facilitates the manufacture of macrocellular foams useful for acoustic absorption having increased amounts of particulate additives that provide certain desired properties difficult to achieve without the particulate additives, such as improved flame retardancy.

    摘要: Foam a polymer blend of (a) a high melt strength polypropylene (HMS PP); (b) a linear or substantially linear polypropylene that has a melting point within ten degrees Celsius of (a), a melt flow rate that is significantly different than (a) and that is miscible with (a); and, optionally, (c) a polyethylene that is immiscible with (a) produces a polymeric foam having an average cell size of at least four millimeters and that has an inherent open-celled content of at least 40 percent. The HMS PP makes up 60 weight percent(wt %) or more and 90 wt % or less of the total combined weight of (a) and (b). Component (c) makes up 60 wt % or less of the total polymer blend weight.

    摘要: Foamable compositions and soft foams comprise at least an ethylene/α-olefin interpolymer. The soft foam has a density from about 10 to 150 kg/m3. The foamable compositions further comprise a blowing agent. The ethylene/α-olefin interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. Methods of making the foamable compositions and soft foams; and foam articles made from the soft foams are also described.
