產(chǎn)品介紹 - 無(wú)鹵白色覆蓋膜

Product introduction- White coverlay
無(wú)鹵白色覆蓋膜(CVL)是由聚酰亞胺薄膜涂覆高性能熱固性環(huán)氧樹(shù)脂接著劑,以離型紙做隔離層,在聚酰亞胺薄膜表面涂覆高性能白色油墨,經(jīng)高溫固化后形成的絕緣耐熱膠膜。具有優(yōu)良的柔軟性,耐黃變,耐高溫,高反光率等性能。適用于高檔LED系列產(chǎn)品,如汽車(chē)尾燈、轉(zhuǎn)向燈,背光源…

No halogen white coverlay is made of polyimide film coated high performance thermosetting epoxy resin adhesive, release paper as isolation layer, coating on the surface of the polyimide film with high performance white ink, curing at high temperature to form the heat insulation film. With excellent flexibility, yellowing resistance, high temperature resistance, high reflection rate and other properties. This series of products are suitable for high grade LED products,such as car taillights, steering lights, backlight and so on.
