High-temperature-resistant double-sided silicon-free isolating membrane

一种耐高温的双面无硅隔离膜

Abstract

The utility model discloses a high-temperature-resistant double-sided silicon-free isolating membrane which takes a BOPP film as a base material, and is characterized in that a transparent polyester film is connected to one side of the BOPP film through an adhesive; and the other side of the BOPP film is connected with a flame retardant acrylic polymer coating. The high-temperature-resistant double-sided silicon-free isolating membrane disclosed by the utility model has the characteristics of flat and smooth surface, resistance to fold, tear, particles, bubbles, pinholes and foreign impurities, excellent physical and mechanical properties, high surface evenness, high high-temperature resistance, dimensional stability in press fit, double-sided release property and the like. The membrane is excellent in flame retardant property and filling property and is a high-end preferred material for PCB precise circuit press-fit isolation.
一种耐高温的双面无硅隔离膜,它以BOPP薄膜为基材,其特征是在BOPP薄膜的一面通过胶粘剂连接透明聚酯薄膜,BOPP薄膜的另一面连接阻燃性丙烯酸酯类聚合物涂层。本实用新型的特点是:薄膜表面平整光洁、无折皱、撕裂、颗粒、气泡、针孔和外来杂质,物理机械性能优良、表面平整度好、耐高温性好、压合时尺寸稳定及双面离型等特点,本产品阻燃性能和填充性能非常优秀,是高端PCB精密线路压合隔离的首选材料。
