Nastro Xinst Polyimide, noto anche come nastro Kapton, commonly known as gold finger tape, is based on polyimide film and uses imported silicone pressure sensitive adhesive. It has high and low temperature resistance, acid and alkali resistance, solvent resistance, and electrical insulation ( Level H), radiation resistance and other properties. Through special processing of high temperature resistant insulating materials based on polyimide film materials, it has excellent insulating properties, durability, acid and alkali resistance, high temperature tape has excellent electrical properties, high insulation, high temperature resistance, low temperature , Acid and alkali resistance, low electrolysis, good mechanical properties, friction resistance, tear resistance, special adhesion treatment, strong adhesion, no residue is covered on the surface after tearing.

1. Characteristics and application of polyimide tape

1. In the electrical and electronic industry, it can be used for the insulation package of the H-level motor and transformer coils that require higher temperature, the coil end of the high-temperature resistance is fixed, the thermal resistance protection of the temperature measurement, the tangle of the capacitor and the wire, etc. Junction insulation.

2. It can be used as electronic protective glue in the circuit board manufacturing industry, especially for SMT temperature protection, electronic switches, PCB finger protection, electronic transformers, relays and other electronic components that need to withstand high temperature and moisture protection. And according to special process needs, use low static flame retardant polyimide tape! High temperature surface reinforcement protection, metal material high temperature spray paint, sandblasted coating shielding surface protection, high temperature spray paint baking, easy to peel off without residual glue. It has the advantages of high temperature resistance, high tensile strength, good chemical resistance, no residual glue, ROHS environmental protection and halogen-free.

Second, the identification method of xinst polyimide tape

1. Guarda i materiali

Il nastro adesivo in poliimmide è composto principalmente da due componenti principali: materiale di base e colla. Se si tratta di un nastro di poliimmide falso, sia la resistenza al calore che le prestazioni di isolamento sono di gran lunga inferiori rispetto al nastro di poliimmide reale.

2. Odore

Se il nastro in poliimmide ha un forte odore e acidità, il nastro in poliimmide potrebbe essere falso e la sua viscosità e ritenzione saranno molto scarse.

3. Prova ad alta temperatura

Il test effettivo ad alta temperatura viene eseguito su nastro di poliimmide. Dopo l'alta temperatura, controllare la forza di pelatura per vedere se ci sono residui di colla, restringimento e altri fenomeni. Perché il vero nastro di poliimmide di solito ha una resistenza al calore da 120 a 260 gradi.

4. Guarda

See the brightness of the surface of the polyimide tape. Generally speaking, the high-temperature tape has poor quality, a little dark color, and the possibility of breaking is very high, and the strength is poor. On the contrary, polyimide tape has good quality and good surface gloss.

5. Conduct material testing

When testing, please refer to the instructions of the polyimide tape. Due to the different types, some polyimide tapes have a strong viscosity after high temperature, some tear after high temperature without residual glue, and some are at high temperature after deformation, so it still depends on what your tape is

A large number of applications of polyimide high-temperature adhesive tape in welding protection, high-temperature insulation strapping of transformer coils; capacitor insulating materials, PCB board high-temperature spray shielding protection, cell phone lithium battery manufacturing strapping.
