Victrex®PEEK™取代了等离子火炬绝缘的聚酰亚胺

ESAB焊接和切割产品，总部位于美国南卡罗来纳州，已转向Victrex®PEEK™聚合物用于血浆切割火炬中的电绝缘体。
Replacing a leading brand of polyimide, the polymer offers the same insulation and high temperature performance but provides more cost-effective processing and superior heat ageing and creep resistance.

血浆切割火炬用于切割和制造金属零件。他们利用非常高的电压电气放电来在电极（火炬体）和工件之间创建一个称为飞行弧的弧线。弧线通过喷嘴头的一个小孔，以及极高的温度气体（例如空气）的气温到金属部分。

A plasma cutting torch has typically two electrical potentials which must be insulated from each other. Stan Severance, Staff Engineer at ESAB explains: “The Victrex® PEEK™ polymer绝缘体位于火炬的头部，必须将电极电势与喷嘴电势分开。绝缘子必须在高频和极端温度下，尤其是在气冷火把下，最多可承受高达10,000伏的电压。”

ESAB tested a variety of different materials before switching toVictrex®PEEK™聚合物，可提供长期的操作可靠性和一致的处理性。
