What is high temperature insulating tape?

by:CROWN     2022-01-21

High temperature tape, that is, adhesive tape used in high temperature working environment. Mainly used in the electronics industry, the temperature resistance is usually between 120 ℃ ~ 260 ℃, often used for painting, baking varnish leather processing, painting and masking and fixing in the process of electronic parts, printed circuit boards and high temperature treatment masking. High temperature tape includes KAPTON high temperature tape. Teflon high temperature tape. High temperature masking tape. PET green high temperature tape. High temperature double-sided tape, etc.

Features

Teflon high temperature tape has the following characteristics:

1. Not sticky;

2. High and low temperature resistance, the product can withstand temperature up to 260℃ for long-term use;

3. Corrosion resistance;

4. Low friction. Wear resistance;

5. Moisture resistance. High insulation;

Conventional product thickness is 0.08MM, 0.13MM, 0.18MM (thickness can be customized), the color is brown and white.

Teflon high temperature tape is mainly used for:

1. Insulation cladding for wire and cable industry;

2. Insulation lining for electro-oxygen industry;

3. The surface cladding of the storage tank roller and the lining of the friction surface of the guide rail can be directly attached to various large planes and regular curved surfaces (such as rollers). The operation is simple, eliminating the need for professional equipment for spraying PTFE materials. Special process and must be transported to a professional spraying factory for processing;

4. Used in textile, food, medicine, wood processing and other departments as insulating high temperature materials;

5. Color printing and packaging machine. Microwave drying of plastic weaving and drawing machine. Various conveyor belts and various bag-making machines in the clothing industry of hot-sticking, sealing and pressing, and hot-pressing sealing end faces of sealing machines.

High temperature PET green tape has the following characteristics:

1. Initial adhesion. Excellent adhesion;

2. No glue residue after baking. No edge warping. No falling off;

3. Solvent resistance;

4. Acid and alkali resistance;

5. Long-term temperature resistance 200℃.

The thickness of the high temperature PET green tape is: 0.055mm.0.060mm.0.070mm.0.080mm.0.10mm.0.12mm.0.13mm (the thickness can be customized). Colors are: light green. Grass green. Dark green. Dark green. Yellow. Blue. Sky blue. Black. Transparent (customizable colors).

High temperature PET green tape is mainly used in:

1. Chassis. Tempered cups and other high temperature spray powder shielding;

2. High temperature shielding of PCB board;

3. PCB board baking tin. Gold-plated shielding;

4. LED dot matrix block, digital tube, electrical LED display panel and other high temperature glue-filled shielding;

Identification method

Distinguish high temperature tape. Polyimide high temperature tape:

(1). Appearance. Taste;

(2). Residue after ignition and combustion;

(3). Actual high temperature test, over 260° high temperature, check whether there is residual glue, shrinkage and other phenomena.

Polyimide high temperature tape can be customized according to customer's withstand voltage requirements. The specially treated high temperature resistant insulating material polyimide film is the base material, which has excellent insulation, wear resistance, acid and alkali resistance, can withstand high temperature of 300 ℃ / 10 minutes, and can be used for a long time at 180 ℃. The length of the product specification is 33M, and the width can be arbitrarily cut into different shades of amber series.

High temperature tape This product has excellent electrical properties, high insulation, high temperature resistance, low temperature, acid and alkali resistance, low electrolysis, good mechanical properties, abrasion resistance, tear resistance, special adhesive treatment, strong adhesion, tearing No glue residue is left on the masked surface after removal.

Polyimide high temperature tape is widely used in anti-soldering protection, high temperature insulation bundling of transformer coils; capacitor insulation material, high temperature spraying shielding protection of PCB gold fingers, and manufacturing and bundling of mobile phone lithium batteries. Purpose: To protect the polyimide high temperature tape insulation tape produced by Goldfinger Company, it is made of polyimide film as the base material and coated with high temperature resistant silica gel. Finger protection.

Storage method

1. The tape should be stored in the warehouse to avoid sunlight and rain; it is forbidden to contact with acid-base oil and organic solvents, keep it clean and dry, 1m away from the discovery device, and the room temperature is between -15℃~40℃;

2. The tape should be placed in rolls, not folded, and should be turned over once a quarter when the storage time is too long;

3. When loading and unloading the conveyor belt, it is best to use a crane, and use a rigging with a beam to hoist it smoothly to avoid damage to the edge of the belt.

4. The type and specification of the tape should be reasonably selected according to the use needs and specific conditions;

5. It is not allowed to connect (match) tapes of different varieties, specifications, models, strengths and layers of cloth together for use;

6. It is best to use hot vulcanized glue for conveyor belt joints to improve reliability and maintain high effective strength;

7. The diameter of the conveying roller of the conveyor and the minimum diameter of the pulley of the conveying belt shall comply with the relevant regulations;

8. Do not make the tape meander or creep, keep the drag roller, the vertical roller flexible, and the tension should be moderate;

9. When the conveyor is equipped with baffles and cleaning devices, the abrasion of the belt should be avoided;

10. Cleanliness is the basic condition for the good operation of the tape, foreign matter will affect the tape eccentricity, tension difference, and even breakage;

11. When the tape is found to be damaged at an early stage during use, the cause should be found and repaired in time to avoid adverse consequences.
