英文名稱(chēng):Polyterafluorethylene(PTFE)Skived Sheet Tape Film
>> 特征Features
聚四氟乙烯板、車(chē)削帶由聚四氟乙模壓毛坯車(chē)削加工制得,它具有優(yōu)良的介電性能,不老化,最好的耐化學(xué)腐蝕性能及廣闊的使用強(qiáng)度范圍。薄膜為不定向薄膜,不定向薄膜經(jīng)壓研制成定向和半定向薄膜。PTFE resin is first moulded into work-blank and then skived.The PTFE resin skived sheet & tape are highly dielectric.chemicaI resistant and not aging. They have a wide range ofoperation temperature.
