二、颜色：白色或其它颜色。
Color: White or other color
三、电气特性：耐高低温，耐腐蚀性，低摩擦，耐磨损性，抗湿性，高绝缘。PTFE薄膜带经拉伸产生微孔，用它做导线绝缘层耐温等级高，柔软性好，屏蔽性能好，通讯频率高衰减低，热膨胀系数小。
Electrical characteristics: High and low temperature resistance, corrosion resistance, low friction, wears resistance, moisture resistance, high insulation. PTFE film tape produce micro porous by stretching, temperature resistance rating is high if use it as conductive wire insulation layer, good softness, good shielding property, low attenuation, high frequency communications, low coefficient of-thermal expansion.
四、分切及包装：分切最小宽度为5mm，内孔大小为52mm或76mm；收卷最大外径为800mm，纸箱包装。
Slitting and packaging: Slitting minimum width of 5mm, bore size of 52mm or 76mm; the winding maximum outer diameter of 800mm, carton packaging.
