Tape Selection Substrate

Polyimide film tape to polyimide film as the substrate, single-sided coated high-performance silicone pressure-sensitive adhesive, single-sided fluorine-free materials from composite or non-composite two types of materials. Coating high precision to ± 2.5um, no scratches, drawing and other phenomena., Good shear, easy-type die-cutting processing, with excellent high temperature resistance and solvent resistance!Tape

In the circuit board manufacturing industry can be used for electronic protection paste, especially for SMT temperature protection, electronic switches, PCB board finger protection, electronic transformers, relays and other high temperature and moisture protection to protect the electronic components. And according to the needs of a special process supporting a low static and flame retardant polyimide tape! High temperature surface reinforcement protection, metal materials, high temperature spray paint, sandblasting coating masking surface protection, high temperature paint baking, easy to peel without residual glue.Tape

In the electrical and electronic industry can be used for high requirements of the H-class motor and transformer coil insulation bandage, high temperature coil end banding fixed, thermal resistance protection, capacitance and wire entanglement and other under high temperature working conditions of the bonding insulation. PP film transparent tape material surface can be corona treatment or dichromate oxidation of the surface, and then coated with the surface coated with adhesive, the amount of coverage of about 20 to 50 grams per square meter (by dry volume ), While the back of the substrate is coated with a separating agent.Tape

This transparent tape material should have the following properties: transparent tape material edge tear strength should be less than 200 grams of force, preferably between 5-40 grams of force in order to facilitate the use of force to break, if more than 200 grams of force on Pulling up. The edge tear strength can be determined according to the JTSC 2318 standard method. Remove the splines along the longitudinal direction, suspend the specimen, and fix a weight, with a mysterious pendulum, and the determination of the tear strength at right angles is a heavier weight that refers to a certain height and falls from the mountain. The right-angled tear is the force at which 50% of the total number of specimens can be broken when the weight is free to fall. Test face Y20 ℃, the speed of 4.5 m / s under.Tape
