2024-06-26
Polyimide tape is a very eye-catching in the appearance of the special tape varieties, gold finger tape has another name is polyimide tape, the use of imported silicone adhesive, so it has excellent high and low temperature resistance, can be used in the temperature range of -60 ~ +280℃. Single side coated with high performance silicone pressure sensitive adhesive, there are single side fluorine plastic release material composite or non-composite two kinds of materials.
Polyimide tape is mainly based on polyimide film as the substrate, using imported silicone pressure sensitive adhesive, rubber system silicone, color is amber, category for electronic products with high temperature tape. Polyimide TAPE is commonly known as gold finger tape, KAPTON TAPE, the international trade name KAPTON tape.
Characteristics of polyimide tape:
1, with high and low temperature resistance, acid and alkali resistance, solvent resistance, electrical insulation (H class), radiation resistance and other properties.
2. Polyimide tape has high insulation grade, high and low temperature resistance, acid and alkali resistance, solvent resistance and radiation resistance.
Main uses of polyimide tape:
1, suitable for mobile phone battery, coil insulation and electronic circuit board wave soldering shield, other high temperature shield.
2. The tape is based on polyimide film and coated with high-performance silicone pressure sensitive adhesive on one side. It has the advantages of high temperature resistance, high tensile strength, good chemical resistance, no residual glue, and RoHS environmental protection and halogen-free in electronic and electrical industry and circuit board manufacturing industry.
3, suitable for electronic circuit board wave soldering shield, protective finger and high-grade electrical insulation, motor insulation, as well as lithium battery positive and negative and ear fixing.
4, used in high-grade electrical insulation and lithium battery positive and negative ear fixing, as well as suitable for circuit board (PCB) over wave soldering, to protect the gold finger parts, easy to tear, not easy to break, no residue after tearing.
Product Features Features:
Polyimide tape because of the functional characteristics of the product nature, the product is mainly used in high-grade electronic insulation materials and auxiliary fixed use in a variety of high temperature environment, such as flexible circuit board production, high temperature bonding of electronic components; On the other hand, it is especially suitable for fixing the soft circuit board patch with the tool after reflow welding.
Characteristic 1: high temperature tape polyimide high temperature insulation tape is suitable for electronic circuit board peak soldering shielding, protective gold finger, high-grade electrical insulation, motor insulation, lithium battery positive and negative electrode fixing and high temperature plating, painting, spraying and other electronic parts of high temperature shielding protection.
Characteristics 2: high temperature tape polyimide high temperature insulation tape is widely used in welding protection, transformer coil high temperature insulation bundling; Capacitor insulation material, PCB gold finger high temperature spray shielding protection, mobile phone lithium battery manufacturing strapping.
Characteristic 3: high temperature resistant tape polyimide high temperature resistant insulation tape specifications: length 33M, 66M, maximum width 500mm (can be small size cutting), total thickness: 0. 06mm, 0. 07mm, 0. 08mm, 0. 1mm, 0. 12mm, at the same time can be punching molding according to customer requirements.
Special four: polyimide double-sided tape, also known as double-sided tape, is 0. 025MM polyimide film as the base material, double-sided coating imported organic silicone, the total thickness is 0. 1MM. Can be single-sided or double-sided composite PET fluoroplastic release film.
This product has excellent electrical performance, high insulation, high temperature resistance, low temperature, acid and alkali resistance, low electrolysis, good mechanical properties, friction resistance, tear resistance, special adhesive treatment, strong adhesion, no residual glue is left on the shielded surface after tearing, used in high-grade electrical insulation and lithium battery positive and negative ear fixing function, and PCB gold finger high temperature spraying shielding protection, easy to tear off. It is not easy to break, leaving no trace after tearing.
Product use:
Polyimide tape has the properties of high and low temperature resistance, acid and alkali resistance, electrical insulation, radiation protection, high adhesion, soft adhesion and retear no residual glue. It is suitable for coil, wire entanglement insulation, capacitor and other electronic products. Has been widely used in electronic industry, printed circuit board gold-plated fingers, hot air tin hole processing and tin furnace in various stages of shielding protection; It is also commonly used for coil, transformer motor, capacitor and wire entanglement, and fixation of lithium battery pole ears. Heating process protection of electronic products and various high temperature shielding protection. The biggest advantage is that when you tear off the goldfinger tape after use, there will be no residual glue on the surface of the protected object.
Polyimide tape, also known as Kapton tape, commonly known as golden finger tape, is based on polyimide film as the substrate, the use of imported silicone pressure sensitive adhesive, with high and low temperature resistance, acid and alkali resistance, solvent resistance, electrical insulation (H class), radiation resistance and other properties. Suitable for electronic circuit board wave soldering shielding, protective finger and high-grade electrical insulation, motor insulation, and lithium battery positive and negative and ear fixing.
Polyimide tape has one side fluorine plastic release material composite or non-composite two kinds of materials. Coating accuracy up to ±2. 5um, no scratches, wire drawing and other phenomena. Good shear, easy punching die cutting, with excellent high temperature resistance and solvent resistance!
In the electronic and electrical industry, circuit board manufacturing industry has the advantages of high temperature resistance, high tensile strength, good chemical resistance, no residual glue, in line with RoHS environmental protection halogen-free.
In the circuit board manufacturing industry can be used for electronic protection paste, especially suitable for SMT temperature protection, electronic switches, PCB gold finger protection, electronic transformers, relays and other need high temperature and moisture protection of electronic components. And according to the needs of the special process with low static electricity and flame retardant polyimide tape! High temperature surface reinforcement protection, metal material high temperature paint, sand blasting coating shield surface protection, high temperature paint baking, easy to peel without leaving residual glue.
In the electronic and electrical industry can be used for higher requirements of the H class motor and transformer coil insulation, high temperature coil end bandage fixed, temperature resistance protection, capacitance and wire entanglement and other adhesive insulation under high temperature working conditions.
