Teach you how to correctly identify gold finger high-temperature tape

One Instructions for Golden Finger Adhesive Tape

Adhesive tape is a commonly used item in daily production, andGolden Finger High Temperature Adhesive TapeIt is a relatively special type of adhesive tape, also known as Kapton tape or polyimide tape.

This tape is based on polyimide film and coated with high-performance silicone pressure-sensitive adhesive on one side. There are two types of materials: single-sided fluoroplastic release material composite or non composite. Coating with high precision up to ± 2.5um, no scratches, wire drawing or other phenomena, good shear performance, easy to punch die cutting processing, excellent high temperature resistance and solvent resistance. The storage conditions for gold finger tape are 10-30 ℃ and relative humidity of 40-70%; Avoid direct sunlight and high temperature (above 40 ℃) and high humidity (75% RH) environments.

II Characteristics of Golden Finger Adhesive Tape

Golden finger tape has properties such as high and low temperature resistance, acid and alkali resistance, electrical insulation, radiation resistance, high adhesion, soft adhesion, and no residue after tearing. When the golden finger tape is torn off after use, there will be no residue on the surface of the protected object.

III Application of Golden Finger Adhesive Tape

Coatings: Used as insulation paint for electromagnetic wires or as high-temperature resistant coatings.

Advanced composite materials: used for aerospace, aircraft, and rocket components. It is one of the most heat-resistant structural materials.

Fiber: Its elastic modulus is second only to carbon fiber, and it is used as a filtering material for high-temperature media and radioactive substances, as well as bulletproof and fireproof fabrics.

Foam plastic: used as high temperature resistant and heat insulating material.

Engineering plastics: There are thermosetting and thermoplastic types, and thermoplastic types can be molded by compression molding, injection molding, or transfer molding. Mainly used for self-lubricating, sealing, insulation, and structural materials.

Separation membrane: used for the separation of various gases, such as hydrogen/nitrogen, nitrogen/oxygen, carbon dioxide/nitrogen, or methane, to remove moisture from air hydrocarbon feed gases and alcohols. It can also be used as a pervaporation membrane and ultrafiltration membrane.

Photoresist: Some polyimides can also be used as photoresists. There are negative and positive adhesives, and the resolution can reach sub micron level. When combined with pigments or dyes, it can be used for color filter films, greatly simplifying the processing steps.

Application in microelectronic devices: used as a dielectric layer for interlayer insulation, and as a buffer layer to reduce stress and improve yield. As a protective layer, it can reduce the impact of the environment on the device and also act as a shield for alpha particles, reducing or eliminating soft errors in the device.

Polyimide, an alignment agent used in liquid crystal displays, plays a very important role in the materials of TN-LCD, SHN-LCD, TFT-LCD, and future ferroelectric liquid crystal displays.

Electro optical materials: used as passive or active waveguide materials, optical switch materials, etc. Fluorinated polyimides are transparent in the communication wavelength range, and using polyimide as a chromophore matrix can improve the stability of the material.

Moisture sensitive materials: The principle of linear expansion due to moisture absorption can be used to make humidity sensors.

4 Distinguishing the authenticity of gold finger high-temperature tape

With the increasing demand for high-temperature adhesive tape, manufacturers of golden finger high-temperature adhesive tape have emerged like mushrooms after rain. The increasing number of manufacturers in various regions has led to a discrepancy in the quality of the high-temperature adhesive tape sold on the market, making it difficult for many friends to distinguish between genuine and fake products. Here are a few methods that can teach you to distinguish the authenticity of gold finger high-temperature tape.

Method ❶: Look at the material

Golden finger high-temperature tape is mainly composed of two parts: substrate and adhesive. If it is a fake gold finger high-temperature tape, both its temperature resistance and insulation performance are far lower than real gold finger high-temperature tape.

Method ❷: Smell

If the smell of the golden finger high-temperature tape is strong and accompanied by a sour odor, then this type of golden finger high-temperature tape is highly likely to be fake, and its stickiness and retention will also be very poor.

Method ❸: Conduct high temperature testing

Conduct actual high-temperature testing on the gold finger high-temperature tape, and after passing through high temperature, check the peeling force for any residual adhesive, shrinkage, and other phenomena. Because the temperature resistance of real gold finger high-temperature tape is usually between 120 degrees and 260 degrees.

Method ❹: Look at the appearance

Judging from the brightness of the surface of the golden finger high-temperature tape, generally speaking, low-quality high-temperature tape has a slightly darker color and a very high probability of breakage, with poor strength. On the contrary, high-quality gold finger high-temperature adhesive tape has a relatively good surface gloss.

Method ❺: Observe the residues after combustion

You can first bake it with a lighter for 1 to 2 seconds, and then touch it with your hand. If it's ordinary, the glue will stick to your hands when touched after burning, but if it's real gold finger high-temperature tape, there won't be any glue on your hands.

Method ❻: Conduct material testing

When testing, it is important to refer to the instructions for the gold finger high-temperature tape. Due to different types, some gold finger high-temperature tapes have the same strong adhesion after high temperature resistance, some tear off without leaving any residue after high temperature resistance, and some do not deform after high temperature resistance. Therefore, the specific type of tape depends on what kind of tape you have.
