Abstract: The present invention relates to a polymer composition, which is a silanol condensation catalyst masterbatch, comprises a matrix, comprising a silane containing drying agent, and at least one silanol condensation catalyst, wherein each catalyst has a water content which is 0.

Abstract: The invention relates to a foamable ethylene polymer composition comprising at least one antioxidant, at least one process aid and at least 80 wt % of a peroxide-treated ethylene polymer composition. The foamable ethylene polymer composition has melt strength of at least 2 cN, a density of 940 to 970 kg/m3, and dissipation factor measured at 1.9 GHz of 50-80?10?6. The invention further relates to a process for making such a foamable ethylene polymer composition, and use of the foamable ethylene polymer composition in a foamed cable insulation.

Abstract: This invention relates to silane moisture curable polymer composition and more particularly, to such a polymer composition that is highly diluted by a non-silane containing component, while retaining good high temperatures properties. The invention is a polymer composition comprising a base resin comprising less than 59 wt % of a silane crosslinkable polyethylene (A), an thermoplastic polyolefin free from silane groups (B) wherein the polymer composition comprise a filler with a BET Nitrogen Surface Area larger than 3 m2/g (C). The invention also relates to a cable layer of such polymer composition suitably a semiconducting layer of a power cable.

Abstract: A polyethylene composition comprising a polyethylene comprising hydrolysable silane groups and a silanol condensation catalyst that can be crosslinked. The crosslinkable polyethylene comprises trimethoxy silane and/or triethoxy silane groups and the silanol condensation catalyst comprises an inorganic tin compound in which a tin atom has no covalent bond to a carbon atom. The crosslinked composition can be used in a cable, such as an insulation layer.
