二、顏色：白色或其它顏色。
Color: White or other color
三、電氣特性：耐高低溫，耐腐蝕性，低摩擦，耐磨損性，抗?jié)裥?，高絕緣。PTFE薄膜帶經(jīng)拉伸產(chǎn)生微孔，用它做導(dǎo)線絕緣層耐溫等級(jí)高，柔軟性好，屏蔽性能好，通訊頻率高衰減低，熱膨脹系數(shù)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、分切及包裝：分切最小寬度為5mm，內(nèi)孔大小為52mm或76mm；收卷最大外徑為800mm，紙箱包裝。
Slitting and packaging: Slitting minimum width of 5mm, bore size of 52mm or 76mm; the winding maximum outer diameter of 800mm, carton packaging.
