金屬化聚酯膜
Metallized PET(polyethylenetherephtalate) films
◆ 特點Feature
金屬化薄膜是在真空狀態(tài)下,將鋁或鋅鋁蒸鍍到薄膜的表面。該材料介電常數(shù)大,絕
緣電阻高,耐熱性能好,抗拉伸性能好,適用于制作金屬化聚酯薄膜電容器。
The AL or ZN-AL layer deposited by evaporation under vacuum,big dielectric constant and
insulation resistance,and excellent shrinkage and tensile strength.Widely used in Metallized
PET film capacitors.
