<p>PURPOSE:To obtain a fire-resistant penetrating member, consisting of a heat insulating and heat conductive material mixture having different specific gravities and curing type material separating and curing into a heat insulating layer and heat transfer layer during curing, capable of exhibiting both heat insulating and transfer actions and suitable for fireproofing and fire-resisting works for electric wires, cables, etc. CONSTITUTION:The aimed member, consisting of a curing type material prepared by blending two or more kinds of (A) a heat insulating material having a high specific gravity (preferred example; silicic acid compound, such as calcium silicate powder) and (B) a heat conductive material having a small specific gravity (preferred example; metal-containing plastic, such as copper powder-containing PE foam) and capable of separating and curing into a heat insulating and heat conductive layers during curing.</p> |
