Abstract: The invention relates to the use of a composition comprising linear low density polyethylene and an inorganic acid in health care applications. The inorganic acid may be selected from the group consisting of aluminum oxide, zinc oxide, calcium oxide, calcium hydroxide, magnesium oxide, magnesium hydroxide, hydrotalcites and any mixtures of any one of these inorganic acids. Furthermore, the composition may further comprise low density polyethylene, for example in a weight ratio of 10/90 to 50/50 with linear low density polyethylene.

Abstract: The invention is directed to a masterbatch comprising a nucleating organic compound which, on changing to the solid phase, forms crystals and which in its melt phase is soluble in the molten polyethylene and polyethylene. The ingredients of this masterbatch are applied as a nucleating agent masterbatch during the production of polyethylene foam.

Abstract: The invention is directed to a process for the addition of additives to ultra high molecular weight polyethylene. A master fluff comprising virgin ultra high molecular weight polyethylene and an additive is added to virgin ultra high molecular weight polyethylene in continuous mixing equipment. The additive may be a corrosion inhibitor, an acid scavenger, a (UV) stabiliser, an antioxidant, a lubricant, an antimicrobial agent, a colorant, a pigment, a whitener, a crosslinker, a filler, an antifogging agent, an antistatic and/or a flame retardant.

Abstract: The invention is directed to an ultra high molecular weight polyethylene powder composition comprising precipitated magnesium salt of a carboxylic acid. The process for the addition of the precipitated magnesium salt of a carboxylic acid to ultra high molecular weight polyethylene takes place by adding a master fluff comprising virgin ultra high molecular weight polyethylene and precipitated magnesium salt of a carboxylic acid to virgin ultra high molecular weight polyethylene. The precipitated magnesium salt of a carboxylic acid results in an improved corrosion behaviour and in improved colour characteristics. Furthermore the free flowing properties of the powder are positively influenced by this additive.

Abstract: The invention is directed to polyethylene foam based on a blend comprising 95.5-99.5% by weight low density polyethylene and 0.5-4.5% by weight high density polyethylene and a nucleating agent. The invention is also directed to a process for physical foaming of a blend comprising 95.5-99.5% by weight low density polyethylene and 0.5-4.5% by weight high density polyethylene in the presence of a physical blowing agent and a nucleating agent.
