ION EXCHANGE BODY AND PRODUCTION METHOD THEREFOR

摘要

Provided is an ion exchange body which has excellent electrical characteristics, has low electrical resistance, and furthermore has superior mechanical strength, while simultaneously having superior contamination resistance. The ion exchange body comprises a melt extrusion-formed body with a resin composition including ion exchange resin particles and a low melting point polyolefin resin having a melting point no higher than 170°C. The aforementioned melt extrusion-formed body is characterized by a) comprising the aforementioned ion exchange resin particles at a proportion of least 30% and less than 50% by weight, and having the aforementioned low melting point resin at a ratio of over 100 and no more than 150 parts per 100 parts of the aforementioned ion exchange resin particles by weight; b) having a melt flow index in the range of 1-5g / 10min when measured at 190°C; and c) having a moisture content of at least 30%.
