Abstract: The present invention relates to a polymer composition comprising (85-100 wt %) of a propylene copolymer based on the total amount of the polymer composition, wherein the comonomer in the propylene copolymer is selected from moiety derived from ethylene, an ?-olefin having (4) to (20) carbon atoms or a combination thereof, wherein the amount of the comonomer is in the range of (0.50 to 4.5) wt % based on the propylene copolymer, wherein the fraction of melted propylene copolymer in the temperature range from (116 to 151° C.) is in the range from (65 to 90) wt % based on the total weight of the propylene copolymer. The present invention also relates to expanded polypropylene (EPP) beads comprising said polymer composition. The invention further relates to the use of such EPP beads. The invention further relates to a process for preparing such EPP beads. The present invention also relates to an article made from said EPP beads. The invention further relates to the use of such article.

Abstract: The present invention relates to a polyethylene composition comprising a) a polyethylene blend comprising from 95.5% to 99.5 wt % low density polyethylene (LDPE) and from 0.5% to 4.5 wt % high density polyethylene (HDPE), wherein the wt % (% by weight) is based the total amount of low density polyethylene and high density polyethylene in the blend, and b) a mixture of glycerol-mono-stearate and glycerol-mono-palmitate.

Abstract: The present invention is directed to a polyolefin resin composition comprising polyolefin and a mixture comprising glycerol ester, primary aliphatic amide and secondary aliphatic amide. The invention relates to a polyolefin foam composition obtained by foaming said polyolefin resin composition in a physical foaming process in the presence of a physical blowing agent.

Abstract: The invention is directed to foamed film comprising a polyethylene foam obtained by physically foaming of a low density polyethylene copolymer with a density between 910 kg/m3 and 935 kg/m3 (according to ISO 1183) and a melt index between 0.10 and 100 dg/minute (according to ASTM D1133) wherein the low density polyethylene is obtained by a high pressure polymerization process of ethylene in the presence of a di- or higher functional monomer.

Abstract: The invention is directed to foamed caps and closure seals comprising as one of the layers polyethylene foam. The polyethylene foam is obtained by foaming of low density polyethylene copolymer obtained by a high pressure polymerization process in the presence of 1,4-butanediol dimethacrylate.

Abstract: A foamed material includes specific amounts of a polystyrene, an organophosphate ester, and a poly(phenylene ether) or a poly(phenylene ether)-polysiloxane block copolymer or a combination thereof. The material is foamed with a C3-C5 alkane blowing agent. The foamed material is useful as insulation in the construction of walls and ceilings.
