Voltoid HP-450

Description:

Voltoid HP-450 is a high density composite consisting of Aramid fiber, filler and polymer binders, It is designed to provide superior flame barrier properties and dimensional stability at elevated temperatures. It has outstanding electrical properties and mechanical properties intermediate to ceramic fiber and Aramid fiber materials. Voltoid HP-450 accepts varnish better than most Aramid papers. Voltoid sheet is available gauges from 0.015" to 0.125" without being laminated.
