Polyimide Coverlay
Film (White)
Polyimide coverlay film is a high-performance thermosetting
converlay. After the Thermosetting Converlay is attached to
the material which needs to be protected, a pressure of 5-10 MPa is
applied by using a quick press at 170-185°C for about 30 seconds ,
then complete the operation. Structure Features The product is easy
to use, only need a quick pressure, without curing later;
Has good adhesion to metal, PET, PVC and other plastics; Has
excellent electrical insulation.
Halogen free white Polyimide 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.
