High Voltage Insulator

タイトルまたは説明

Excellent processing properties and could meet various kinds of technical requirements for both molding and injection. It also has very good insulation properties, hydrophobility, housing tracking, erosion and fire resistance. It is suitable for making high voltage and power transmission equipment such as surge arrester, insulator and casing pipe for railway and city light-train and ***** 　T1、C1、D1、E1 are suitable for molding and T2、C2、D2、E2 are suitable for injection or extrusion. Comparing with common silicone rubber, this product has better tensile strength, elongation at breakage, tear strength properties. It is suitable for those molding product which require high physical and mechanical properties.
