The component was to be used as part of a device to safely deliver a small current to non-planar surfaces. Our standard porous material is permeable and flexible, but hydrophobic, so a hydrophilic treatment was required. Once treated, the pores hold liquid, and the current passes through that liquid. A conductive material is also added, but only in a supporting role: the material itself does not conduct, and the part does not conduct in the dry state. The required shape was achieved by injection moulding.<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\" border=\"1\">\n<tbody>\n<tr>\n<td style=\"width: 50%;\">\n<h5>Background of challenges<\/h5>\n<ul>\n<li>Hydrophobic to hydrophilic<\/li>\n<li>Holding liquid in the pores so that current can pass<\/li>\n<li>Complex continuous protrusion shape<\/li>\n<\/ul>\n<\/td>\n<td style=\"width: 50%;\">\n<h5>Our solution and benefits<\/h5>\n<ul>\n<li>Hydrophilic treatment so that the pores hold liquid<\/li>\n<li>Conduction through the liquid, not through the material itself (no conduction when dry)<\/li>\n<li>Moulded by injection moulding for the complex shape<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<hr \/>\n<table style=\"width: 100%; border-collapse: collapse; background-color: #d90000;\" border=\"1\">\n<tbody>\n<tr style=\"height: 29px;\">\n<td style=\"width: 100%; height: 29px; text-align: center;\"><a href=\"https:\/\/yamahachi-chemical.co.jp\/en\/contact\/\"><span style=\"color: #ffffff;\"><strong>For further information or request, please CONTACT US<\/strong><\/span><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: right;\">\u00a0<\/p>\n\n\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"Article\",\n  \"headline\": \"Porous Parts That Conduct Through Liquid in the Pores\",\n  \"description\": \"Yamahachi Chemical's case study of a custom porous part that carries a small current through the liquid held in its pores.
