ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE POWDER COMPOSITION
摘要
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.
