特征:
聚四氟乙烯薄膜,车削带由聚四氟乙烯悬浮树脂经模压,烧结后车削而成。定向膜是将车削膜再经压延机定向而成,它具有优良的电器绝缘性能、不老化及广阔的使用温度范围。
Characteristic:
Polytetra-fluoro-ethyiene thin membrane,pass through cut tie by
poly-4 fluorous second fluidized resiny extrude,after sinter cut but
succeed,direct membrane transfusives membrane transfusive membrane
mangler direct but succeed again,It has undiniable electrical equipment
insulate behavioural,non-ageing and extensive use temperature limt.
