Black and black tape

· Product description:

Substrate: Polyester film
Adhesive: Polyacrylate
Color: Black
release material: transparent PET silicon release film
Specifications:(500mm) width (100M, 200M) length

· Product characteristics:

Excellent shading effect; The flexible substrate has good adhesion and followability, strong curved surface resistance and anti-warping performance, and also has a good bonding effect on fine edges. The PET release film with medium release degree is used for punching and rotary cutting. It has good processing performance, is not easy to break in high temperature and high speed operation, and does not overflow glue.

· Product Application:

Used for bonding and fixing of backlight modules of 3C products such as mobile phones and digital cameras; used when materials such as glass, metal and plastic parts require extremely thin thickness and shading characteristics.
